Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a shift lever positioning device for an automatic transmission.

[Prior Art] For example, as shown in FIGS. 4 and 5, a conventional shift lever positioning device for an automatic transmission has a positioning device for positioning a shift lever 103 in the vicinity of a shift lever 103 that is movable in the direction of the arrow with a lever shaft 101 as a fulcrum. A position plate 105 is arranged. This position plate 105 has a guide groove 10 having each position such as parking, reverse, neutral, and running.
7 and an uneven positioning groove 109 are provided respectively, an engaging pin 111 protruding from the lever body of the shift lever 103 faces the guide groove 107, and an engaging pin 111 that is incorporated in the connecting member 113 of the shift lever 103 faces the positioning groove 109. It has a structure in which the ball 115 makes elastic contact. Something with this kind of structure,
For example, there is one described in Japanese Utility Model Application Publication No. 56-95713.

[Problems to be solved by the invention] In such a structure, the ball 1 of the connecting portion 113
15 comes into elastic contact with the positioning groove 109, a sense of moderation can be obtained, and the shift lever 103 can be positioned at each position.

Therefore, the ball 115 is located in the positioning groove 109.
Ball 1 is required to make correct contact with ball 1.
The positioning groove 109 with which the ball 15 comes into elastic contact is only as wide as the thickness of the position plate 105, and it is necessary to assemble the ball 115, which is biased by a spring, so that it hits the positioning groove 109 correctly. The work becomes very troublesome. Also, if an assembly error or machining error occurs, the ball 11
5 and the positioning groove 109, this is not desirable in terms of assemblability and workability, such as requiring high assembly accuracy and processing accuracy.

Therefore, the object of this invention is to provide a positioning device for a shift lever for an automatic transmission that facilitates assembly work and provides reliable positioning and a sense of moderation.

[Means for Solving the Problems] In order to achieve the above object, in this invention, in a shift lever that is operated to shift to each position using a lever shaft as a fulcrum, there is provided a shift lever that is attached to either the shift lever or the base plate on the vehicle body side. , a check plate having a continuous uneven locking portion formed along the movement locus of the shift lever is attached, and a pressing body that is capable of elastically contacting and releasing the locking portion from both sides so as to sandwich the locking portion; There is a configuration with a .

[Function] In such a shift lever positioning device,
The locking portions are releasably brought into elastic contact with each other from both sides by the pressing body, so that reliable positioning and a sense of moderation can be obtained. Further, since the check plate is held between both sides by the pressing members, no trouble occurs during assembly, and the assembly can be easily performed.

[Embodiment] Hereinafter, an embodiment of this invention will be described in detail with reference to the drawings of FIGS. 1 to 3.

In the figure, reference numeral 1 indicates a shift lever that is rotatable about a lever shaft 3 as a fulcrum. A handle portion 7 having an operation knob 5 is attached to the upper end of the shift lever 1, and a base end portion serving as a lower end is rotatably supported by a base plate 9 via a lever shaft 3. Further, an arm 13 is integrally connected to the sleeve 11 of the shift lever 1, and a control wire 15 connected to an automatic transmission (not shown) is connected to the arm 13.

The lever body 1a of the shift lever 1 has a position plate 1 that protrudes from the elongated hole 17 of the main body 1a.
A pin-shaped engaging body 23 facing into the guide groove 21 of 9 is provided, and the engaging body 23 is interlocked with the operation knob 5 of the handle portion 7 via an actuation mechanism (not shown). Thereby, by pressing the operation knob 5, for example, the engaging body located in the travel lane is pushed down to the switching lane. As a result, switching to each position becomes possible.

Note that the position plate 19 is fixed to the base plate 9.

The base plate 9 has locking parts 25, 2 on both sides.
One end of the check plate 27 having a
8 and the other end is a free end. The locking portion 25 of the check plate 27 is formed in a continuous uneven shape along the movement locus of the shift lever 1 (arrow in FIG. 1), and a pressing member 29 is in elastic contact with the locking portion 25.

The pressing body 29 consists of a synthetic resin guide part 31 acting on both sides of the locking part 25 and a biasing part 33 such as a bumper rubber that biases the guide part 31, and is a holding case having plate through holes 35a at the front and rear. 3
5 and are assembled facing each other. This holding case 35 is screwed 39 to a bracket 37 extending from the lever body 1a.

In the shift lever positioning device configured in this way, the free end of the check plate 27 is forcibly inserted into the pressing bodies 29, 29 to be held, so that it is difficult to attach it to the base plate 9. Easy to do.

Next, when the shift lever 1 is operated against the urging resistance of the pressing bodies 29, 29, the guide portion 31 of the pressing body 29 slides over the convex portion of the locking portion 25. Therefore, the shift operation of the shift lever 1 can be performed without any problem. Furthermore, when the left and right pressing bodies 29 that come into elastic contact with the locking part 25 get over the convex part, a sense of moderation is obtained and the positioning is ensured. In this case, since the check plate 27 is held between the pressing bodies 29, 29 from both sides, no bending load is applied to the check plate 27, which has the advantage of being able to reduce the plate thickness, contributing to weight reduction. Note that it is also possible to provide the pressing body 29 on the base plate 9 side and the check plate 27 on the shift lever 1 side.

[Effects of the invention] As explained above, according to the shift lever positioning device of this invention, since the check plate is sandwiched from both sides by the pressing body, it can be easily assembled without trouble. I can do it. In addition, since a balanced force acts on the check plate, the check plate has the advantage of being thinner, contributing to weight reduction, and providing a reliable shift lever positioning function and a sense of moderation.
