- the operation unit 21 is in the direction of the first operation axis X and the rotation direction R (the direction of rotation around the axis perpendicular to the plane constituted by both operation axes X and Y). Positioning with respect to the housing 12 is performed with high accuracy. Therefore, when positioning the operation unit 21, it is only necessary to adjust the direction of the first operation axis X. This makes positioning easier and improves positioning accuracy than the operation switch structure (see FIG. 7) of the comparative example without the protrusion 23 and the guide pin 26.
- the guide pin 26 does not hinder the rotation of the protrusion 23 around the first operation axis X and the second operation axis Y. Therefore, a decrease in operability of the operation unit 21 is suppressed.
- the portion of the projecting portion 23 that contacts the guide pin 26 by rotating about the first operating axis X is preferably a smooth curved surface such as a cylinder.
- the operation unit 21 smoothly swings around the first operation axis X, so that the force necessary to swing around the first operation axis X and the second operation axis Y is uniform. become. In this way, a decrease in operability of the operation unit 21 is further suppressed.

It preferably extends along an axis A different from the operation axis Y. The straight line A passes through the intersection of the first operation axis X and the second operation axis Y. As described above, since the pair of arm portions 24 are positioned on the same axis A, there is an advantage that the operation portion 21 is easily swung.
- the arm portion 24 extends along an axis A different from the first operation axis X and the second operation axis Y, so that the operation unit 21 is made to have the first operation axis X and the second operation axis.

- FIG. On the other hand, in the molding method such as injection molding, since the parts are integrally manufactured, the size and shape cannot be confirmed for each operation unit 21 and arm unit 24, and the size and shape of the operation unit 21 and arm unit 24 cannot be confirmed. It is easy for variations to occur. Therefore, it is more preferable that the operation switch structure 20 of the present invention is applied to the operation portion 21, the arm portion 24, the protruding portion 23, and the like manufactured by a molding method such as a resin.
