Two through holes 20 are provided at positions corresponding to both side surfaces. Further, on the side surface of the switch case 12 on the inner side when viewed from the flange portion 16, as shown in FIGS. 1 and 2, there are four recesses 22 communicating with each through hole 20 (only two on one side in FIG. 1). (Shown) is provided.

  As shown in FIG. 2, the terminal base 24 has a substantially H-shaped longitudinal section, and is housed and fixed in the switch case 12. A pair of fixed contacts 28, 28 constituting a part of the contact mechanism are provided on the bottom surface of the box-shaped storage recess 26 opened on the outside of the vehicle. The fixed contacts 28, 28 are formed by exposing a part of a terminal terminal (not shown) insert-molded to the terminal base 24 to the outside, and this terminal terminal is a concave portion on the side opposite to the storage concave portion 26. It is in a state where it can be electrically connected to the outside by a conducting wire 32 which is led out from 30 and connected by soldering. And in order to protect the connection part of this conducting wire 32 and to prevent the intrusion of water droplets into the switch case 12, an adhesive material 34 such as a bond is filled in the opening part of the switch case 12 inside the vehicle.

  As shown in FIG. 2, the operation member 36 is disposed so as to be able to advance and retreat in the housing recess 26, and the operation portion 38 processed into an arc shape protrudes from the opening 2 of the door panel 1 to the outside of the vehicle. Is to be placed. Specifically, the operation member 36 has a rectangular parallelepiped shape that can be accommodated in the accommodation recess 26, and the operation portion 38 at the tip thereof has an arc shape.

  The contact mechanism is actuated by the movement of the operation member 36, and includes fixed contacts 28, 28 disposed on the bottom of the housing recess 26 and an elastic member 42. The elastic member 42 is made of rubber and has a dome shape. A metal movable contact 46 for short-circuiting the pair of fixed contacts 28 and 28 is disposed on the bottom of the base 44 inside.

  The waterproof cover 48 covers the opening end 14 on the vehicle exterior side of the switch case 12 and prevents water droplets from entering the switch case 12. This waterproof cover 48 is insert-molded integrally with the opening end portion 14 of the switch case 12 by an elastic resin such as an elastomer, and as shown in FIGS. 2, 3, and 4, the flange of the switch case 12 is formed.

It is possible to prevent the burr from interfering with the door panel 1 when the switch device 10 is attached.

  Next, the mounting operation of the switch device 10 will be described.

  The opening 2 of the door panel 1 is formed to be slightly larger than the outer shape of the switch device 10 so that the switch device 10 can be easily mounted. The switch device 10 is inserted and pushed in from the outside of the opening 2 of the door panel 1. Then, the elastic arm 13 is engaged with the edge of the opening 2 of the door panel 1 and elastically deformed inward. Further, when the switch device 10 is inserted, the edge of the opening 2 of the door panel 1 comes into contact with the inclined portion 52 of the press-fit rib 50, and the press-fit rib 50 is compressed inward in the beginning. When the flange portion 16 of the switch device 10 comes to a position where the flange portion 16 comes into contact with the surface around the opening 2 of the door panel 1, the elastic arm portion 13 is elastically restored and its tip engages with the edge of the opening 2 of the door panel 1. Then, the switch device 10 is fixed to the door panel 1.

  In this fixed state, the four press-fitting ribs 50 are compressed between the opening 2 of the door panel 1 and the switch device 10. There is no rattling and no abnormal noise is generated by vibration.

  Moreover, since the height of the press-fit rib 50 can be increased by providing the press-fit rib 50 in the recess 22 of the switch device 10, the deformation capacity of the press-fit rib 50 can be increased. Furthermore, since the deformation of the press-fit rib 50 is received by the concave portion 22, the press-fit rib 50 is further easily deformed, and the deformation capacity can be further increased. As a result, even when the tolerance of the opening 2 of the door panel 1 is large, play between the opening 2 of the door panel 1 and the switch device 10 can be reliably absorbed, so that the play of the switch device 10 can be reliably prevented. Further, the switch device 10 can be easily attached.

  The mounting structure of the switch device of the present invention is not limited to the configuration of the above embodiment, and various modifications can be made.

  For example, in the present embodiment, the waterproof cover 48 is formed integrally with the switch case 12, but the present invention is not limited to this. For example, a separate rubber waterproof cover is used as the opening end 14 of the switch case 12. You may make it fix to an adhesive material or a fixing member. Further, the number of press-fitting ribs 50 is not limited to four and can be changed as appropriate.
