The rotating body insertion portion 113 and the engaging portion 117 are formed to have a size that can be inserted almost exactly into the shaft shaft support hole 85 of the rotating body 80 from above. At that time, the engaging portion 117 is inserted into the vertical guide groove 89.

  The click plate 140 is formed by forming an elastic metal plate into a ring shape, and projects a pair of rectangular mounting portions 141 from the outer periphery of a position opposed to 180 °, and has a tongue-like shape formed in each mounting portion 141. The locking piece 143 is configured to be bent upward. An arc-shaped portion between the two mounting portions 141 is an arm portion 145, and both end portions thereof are bent and inclined downward, and a central portion thereof is an elastic contact portion 147 projecting downward.

  The upper case 150 is configured by forming a metal plate in a substantially rectangular shape, and a rotating body shaft support portion 151 that protrudes upward in a cylindrical shape is provided at the center of the upper case 150, and downward from a pair of opposite sides. The attachment piece 153 and the other member attachment piece 155 are protruded toward the end. The outer dimension shape of the upper case 150 is substantially the same as the outer dimension shape of the lower case 10, and the lower case mounting portion is formed of a small hole into which the locking projection 27 of the lower case 10 is inserted. 157 is provided, and a locking piece mounting portion 159 made of a small hole for press-fitting them is provided at a position facing each locking piece 143 of the click plate 140.

  Next, a method for assembling the rotary electronic component 1 will be described. First, the slider 70 is previously brought into contact with the slider mounting surface 105 of the rotating body 80, and at that time, each slider mounting portion 107 of the rotating body 80 is inserted into each mounting portion 73 of the slider 70. The tip of the moving element mounting portion 107 is caulked. On the other hand, the upper surface of the click plate 140 is brought into contact with the lower surface of the upper case 150 so that the pair of locking pieces 143 of the click plate 140 are press-fitted into the pair of locking piece mounting portions 159 of the upper case 150 and temporarily fixed. .

  Then, the rotating body insertion portion 113 of the shaft 110 is inserted into the shaft support hole 85 of the rotating body 80 from above. 3 and 4 show a state after the shaft 110 is completely attached to the rotating body 80, and therefore, the direction of the engaging portion 117 of the shaft 110 and the vertical guide groove of the rotating body 80 are shown. Although the direction of 89 does not correspond, at the time of insertion, either the shaft 110 or the rotary body 80 shown in FIGS. 3 and 4 is rotated 90 degrees. That is, the pair of engaging portions 117 of the shaft 110 are inserted while being engaged with the pair of vertical guide grooves 89 of the rotating body 80. FIG. 10 is an explanatory view of an attaching method for attaching the shaft 110 to the rotating body 80, and shows a state after the shaft 110 is completely attached to the rotating body 80. FIG. However, the illustration of the slider 70 is omitted for convenience of illustration. As described above, when the rotating body insertion portion 113 of the shaft 110 is inserted into the shaft support hole 85 of the rotating body 80, the pair of engaging portions 117 of the shaft 110 are inserted into the pair of vertical guide grooves 89 of the rotating body 80. And the whole is exposed (point E shown in FIG. 10). When the lower surface of the shaft main body 111 of the shaft 110 is brought into contact with the upper surface of the shaft portion 83 of the rotating body 80 (that is, when the rotating body insertion portion 113 is lowered most with respect to the rotating body 80), the engaging portion 117 is engaged. Is located below the lower surface 93a of the engaging portion passage portion 93 of the rotating body 80 and above the lower surface 95a of the stopper portion 95. Therefore, the engaging portion 117 does not move to the stopper portion 95 side. Next, the engaging portion 117 at the point E is rotated in the direction of the arrow A1 shown in FIG. 10 to pass through the engaging portion passing portion 93 to reach a position just below the terminating vertical guide groove 91 (point F). The movement of the engaging portion 117 is surely stopped at the point F when the engaging portion 117 contacts the other stopper portion 95.

  When the engaging portion 117 passes through the engaging portion passing portion 93, the outer peripheral surface of the engaging portion 117 comes into contact with the rotation preventing portion 100 provided on the inner peripheral surface of the rotating body 80 and slides on the surface. Since the rotation prevention unit 100 gradually increases its protruding height as the engagement portion 117 rotates toward the vertical guide groove 91 with a terminal end, the rotating body 80 has an outer diameter (especially the shaft portion 83). The outer diameter is gradually elastically deformed in the increasing direction. As described above, in the rotating body 80, the concave portion 833 is provided on the outer peripheral surface of the shaft portion 83 where the rotation preventing portion 100 of the side wall portion 831 is provided, whereby the thickness of the side wall portion 831 where the concave portion 833 is provided. Therefore, the side wall portion 831 can be given elasticity toward the outer side in the radial direction, and the elastic deformation can be easily and smoothly performed. If the material of the rotating body 80 is made of a material softer than the material of the shaft 110 (for example, the shaft 110 is made of polycarbonate resin and the rotating body 80 is made of POM resin), the rotating body 80 can be more easily given elasticity. it can. If the entire engaging portion 117 passes through the rotation preventing portion 100 (the rotation preventing side 103), the engaging portion 117 is positioned at a position immediately below the vertical guide groove 91 with a terminal end (point F), and at the same time, the rotating body 80 ( In particular, the elastic deformation of the shaft 83) is released and returns to its original shape. That is, the engagement portion 117 reaches the point F by so-called snap-in engagement. Then, when the shaft 110 is raised with respect to the rotating body 80, the engaging portion 117 is inserted into the terminal guide vertical guide groove 91 as shown in FIG. In the state shown in FIG. 10, when the shaft 110 is moved down most with respect to the rotating body 80, the engaging portion 117 is exposed below the vertical guide groove 91 with a terminal. That is, the upper surface of the engaging portion 117 is positioned below the lower surface 93 a of the engaging portion passing portion 93 of the rotating body 80. At this time, since the rotation preventing part 100 is installed on the engaging part passing part 93 side of the engaging part 117, the engaging part 117 is reversed to the engaging part passing part 93 side (moves in the direction opposite to the arrow A1 direction). ) Never to.

  Next, the movable contact body 50 and the reverse body 60 are housed in the switch housing protrusion 31 of the lower case 10. At this time, the lower surface of the contact portion 51 of the movable contact body 50 contacts the second switch pattern 23.

  Then, a rotating body 80 to which the slider 70 and the shaft 110 are attached is installed on the lower surface side of the upper case 150 to which the click plate 140 is attached. It is inserted into the rotating body shaft support 151. Next, the lower case 10 to which the movable contact body 50 and the reversing body 60 are attached is arranged below the rotating body 80 to which the slider 70 is attached, and the lower surface of the upper case 150 is applied to the upper surface of the lower case 10. Touch. At this time, each locking projection 27 of the lower case 10 is inserted into each lower case mounting portion 157 of the upper case 150 and positioned, and at the same time, each mounting portion 141 of the click plate 140 is inserted into each locking recess 29 of the lower case 10. Insert and position. And if each attachment piece 153 of the upper case 150 is bent to the bottom face side of the lower case 10, the assembly of the rotary electronic component 1 is completed. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

  As described above, the rotary electronic component 1 includes the upper and lower cases 150, 10, the rotating body 80 that is rotatably housed in the upper and lower cases 150, 10, and the shaft shaft support hole 85 provided at the lower portion of the rotating body 80. The shaft 110 is attached to the upper case 150 and protrudes from the upper surface of the upper case 150, and the engaging portion 117 provided on the outer periphery of the lower portion of the shaft 110 is provided in the vertical direction provided above and below the inner peripheral surface of the shaft support hole 85. Inserted into the guide groove 89 from the upper part of the shaft support hole 85, exposed to the lower part of the shaft support hole 85, rotated by a predetermined angle, and further provided with an end provided on the inner peripheral surface of the shaft support hole 85 of the rotating body 80. By inserting the engaging portion 117 upward in the vertical guide groove 91, the shaft 110 can be rotated integrally with the rotating body 80 and can move up and down by a predetermined stroke within the rotating body 80. It is constructed attached such that.

  When the shaft 110 is rotated, the engaging portion 117 and the vertical guide groove 91 with the terminal end are engaged with each other. Therefore, the rotating body 80 also rotates with the shaft 110, and the sliding booklet 71 of the slider 70 becomes the substrate 15. The on / off output of the rotary switch is output to each terminal 17. Here, the slider 70 and the third switch pattern 25 constitute detection means (first detection means).

  On the other hand, if the shaft 110 is pressed directly downward, the pressing portion 63 of the reversing body 60 is pressed by the switch pressing portion 115 of the shaft 100 and descends while generating a click sensation, and the contact pressing portion 65 on the lower surface thereof is moved to the movable contact body. 50 movable contact portions 53 are pressed and lowered, and the lower surface of the movable contact portion 53 comes into contact with the first switch pattern 21 of the substrate 15, thereby conducting between the first and second switch patterns 21 and 23. The ON state of the push switch is output to the terminal 19. When the pressure on the shaft 110 is released, the elastic contact force to return the movable contact portion 53 and the reversing body 60 to the original shape automatically causes the shaft 110 to return to the original position. At the same time, the push-type switch is turned off. Here, the reversing body 60, the movable contact body 50, and the first and second switch patterns 21 and 23 constitute detection means (second detection means).

  In the case of the rotary electronic component 1, the shaft 110 has a long vertical stroke, so that the shaft 110 is at the lowest position (that is, until the lower surface of the shaft main body 111 is in contact with the upper surface of the shaft portion 83. 10), the engaging portion 117 of the shaft 110 shown in FIG. 10 is exposed below the end-equipped vertical guide groove 91 (that is, the upper surface of the engaging portion 117 is the engaging portion passing portion 93 of the rotating body 80). And located below the lower surface 93a and above the lower surface 95a of the stopper portion 95). At this time, as described above, since the rotation prevention unit 100 is installed on the engagement portion passage portion 93 side of the engagement portion 117, the engagement portion 117 is reversed to the engagement portion passage portion 93 side (in the direction of arrow A1). Will not move in the opposite direction).

  In other words, since the rotation preventing portion 100 is provided that prevents the engaging portion 117 of the shaft 110 from being inverted toward the vertical guide groove 89 when exposed downward from the vertical guide groove 91 with a terminal end. The pressing stroke of the shaft 110 can be easily and reliably increased without increasing the length of the vertical guide groove 91 with a terminal end (that is, without increasing the height dimension of the rotary electronic component).

  Further, the rotation preventing unit 100 is inserted into the inner peripheral surface of the rotating body 80 facing the outer peripheral surface of the engaging portion 117 when the engaging portion 117 that is inserted into the vertical guide groove 89 and exposed from the lower portion is rotated. It is configured by providing a protruding portion that protrudes in the direction, and the engagement portion 117 rotates while getting over the rotation prevention portion 100 to prevent the engagement portion 117 from reversing toward the vertical guide groove 89 side. Therefore, the shaft 110 and the rotating body 80 can be coupled by the same easy mounting method as the conventional mounting method. In particular, the rotation preventing portion 100 has a shape in which the protruding height is gradually increased from the vertical guide groove 89 side toward the terminally ended vertical guide groove 91 side. The rotation of the shaft 110 can be performed easily and smoothly.
