In other respects, the configuration is the same as that of the first embodiment. In the configuration of the present embodiment, the pressing body 45 and the contact 47 are formed continuously and integrally, and the spring piece 45g for urging the contact 47 downward is also continuous. Since they are formed integrally, there is an advantage that the number of components is reduced.

(Embodiment 5) This embodiment has the structure shown in FIG. 9, and is different from the structure of Embodiment 4 in that a protrusion 45i, a spring piece 45g, and a contact 47 are formed integrally and continuously. ,
The difference is that the holding plate 45 is a separate member. That is, in the configuration of the fourth embodiment, since the pressing body 45 is a molded product made of a synthetic resin and is formed continuously and integrally with the spring piece 45g that requires flexibility, the peripheral portion of the holding opening 45a is formed. In order to restrict the movement of the movable body 40 with
5 was required to be formed relatively thick, but in this embodiment, the pressing body 45, which requires mechanical strength, and the spring piece 45g, which requires flexibility, are separated, so that the structure shown in FIG.
As shown in FIG. 3, a thin material having high mechanical strength can be used for the pressing body 45.
Actually, the mechanical strength is improved by using a sheet metal as the pressing body 45, and the integrated body of the contact 47 and the spring piece 45g is formed of a synthetic resin molded article having excellent lubricity and elasticity. Here, if the material is selected so that the spring constant of the spring piece 45g can be set small, the change in the operation feeling can be reduced even if there is some dimensional error. Other configurations are the same as in the fourth embodiment.

(Reference Example) FIG. 11 shows another configuration as a reference example. This configuration is different from the second embodiment in that the shape of the pressing body 45 is changed. That is, the pressing body 45 is formed in a cylindrical shape having a vertical center line, and the fixing pieces 45e are provided at two places on the outer peripheral surface.
Is formed of a synthetic resin molded product in a shape having Therefore, as shown in FIG. 12, the lower edge of the pressing body 45 becomes the holding opening 45a. Here, holding body 4
5 has a cylindrical shape having a center line in the vertical direction, so that a large mechanical strength for restricting the upward movement of the movable body 40 can be obtained. The spring piece 45b is formed of sheet metal,
One end is fixed to the base 12 together with the pressing body 45 by a fixing screw 46 for fixing the pressing body 45 to the base 12.

In the structure shown in FIG . 11, the mechanical strength of the holding member 45 is ensured to reliably restrict the upward movement of the movable member 40, and the spring constant of the spring piece 45b is reduced to reduce the movable member due to a dimensional error. It is possible to reduce the change in the operational feeling of the contact 40 and to use a material excellent in lubricity and wear resistance for the contact 47. The other configuration is the same as that of the first embodiment, and the description is omitted.
