ン軸５の先端にナツト７止めされた指針である。 An example of a measuring instrument will be explained based on FIG. This example relates to a so-called cooking scale, with reference numeral 1 being an exterior case in which a scale mechanism (not shown) having a measuring spring, a roberval mechanism, etc. is disposed. Reference numeral 2 denotes a weighing pan that is supported by the scale mechanism so as to be movable up and down; 3 is a weighing scale plate disposed within the display window 4 of the case 1; and 5 is a weighing pan that is supported by the scale mechanism and is attached to the weighing pan 2. A pinion shaft 6 that rotates in conjunction with the vertical movement is a pointer fixed to the tip of the pinion shaft 5 with a nut 7.

することができないものである。 In the above configuration, conventionally, a washer is used to prevent the nut 7 from loosening so that the pointer 6 does not rotate on the pinion shaft 5 without permission, but this increases the number of parts and increases the assembly process. In addition, washers cannot sufficiently prevent the nut 7 from loosening.
そこで本考案はかかる問題点を解消した計量器
の指針構造を提供するものである。 Therefore, the present invention provides a pointer structure for a measuring instrument that eliminates such problems.

に向けて若干折り曲げて突出させてある。 An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. That is, U-shaped notches 9 are formed at the upper and lower portions of the outer periphery of the pinion shaft fitting hole 8 of the pointer 6 that fits into the pointer fitting portion 5a of the pinion shaft 5, which has a square cross section. A pointer fixing nut 7 screws each small piece portion 6a formed by the portion 9 into the threaded portion 5b of the pinion shaft 5.
It is slightly bent and protrudes towards the .

止されるものである。 In the above configuration, when attaching the pointer 6 to the pinion shaft 5, as shown in FIG. 7 is screwed onto the threaded portion 5b of the pinion shaft 5, and the nut 7 is pressed against the small piece portion 6a of the pointer 6. If the material of the nut 7 is somewhat softer than the material of the pointer 6, such as brass or synthetic resin, the tips of the small pieces 6a will sink into the bottom of the nut 7, preventing the nut 7 from loosening. It is something that can be prevented. Further, if the material of the nut 7 is harder than the material of the pointer 6, such as steel, each small piece 6a is stretched by the nut 7, and the resulting repulsive force of each small piece 6a loosens the nut 7. is to be prevented.

may be formed.

ゆるみが十分に防止されるものである。 As described above, according to the pointer structure of the measuring instrument of the present invention, the outer periphery of the pinion shaft fitting hole of the pointer is made to protrude at an appropriate position toward the pointer fixing nut that is screwed into the threaded portion of the pinion shaft. Therefore, the washer for preventing nut loosening, which was necessary in the past, is no longer necessary, and the number of parts and assembly steps can be reduced. In addition, if the material of the nut is softer than that of the pointer, the tip of the protruding part will sink into the bottom of the nut, sufficiently preventing the nut from loosening, and if the material of the nut is harder than that of the pointer. In this case, the protrusion is pressed, and the resulting repulsive force of the protrusion sufficiently prevents the nut from loosening.
