A plurality of bosses 15 are protruded from the back surface of the front plate 14, and the bosses 15 extend from the bottom of the recess 13 to the frame 1.
One end of a joint 17 inserted through a through hole 16 penetrating the interior surface of the vehicle is coupled to the boss 15 . The other end of the joint 17 faces the indoor surface of the stile 1, into which a screw 18 is screwed. The through hole 16 has a large diameter at one end on the indoor side, and a stepped portion 19 is formed therein, and the washer 20 inserted through the screw 18 is locked to the stepped portion 19. . Therefore, the front plate 14
is held in the frame 1 by a screw 18 screwed into the frame 1 from the indoor side. At this time, screw 1
The head of the frame 8 is housed in the through hole 16 and does not protrude to the interior side of the stile 1. Incidentally, an insertion hole 21 is formed at a position corresponding to the operation button 12 protruding to the rear surface of the switch unit 11, penetrating from the bottom surface of the recess 13 to the indoor surface of the stile 1.
The operation shaft 5 of the operation push button 6 attached to the cover plate 4 attached to the indoor surface of the stile 1 is inserted into the insertion hole 21 . The cover plate 4 is removably attached to cover almost the entire surface of the indoor side of the frame 1, and is attached to the indoor side surface of the frame 1 in order to accommodate the wiring drawn out from the electric lock and switch unit 11. A concave groove 3 formed along its longitudinal direction is covered by a cover plate 4. This allows for an excellent appearance without exposing the wiring. Furthermore, since the cover plate 4 is removable, the wiring can be easily inspected by removing the cover plate 4. As shown in FIG. 4, the operation push button 6 includes an operation shaft 5 made of synthetic resin molding,
a compression spring 9 that biases the operating shaft 5 in the return direction;
A mounting plate 7 for holding a compression spring 9 between the operating shaft 5 and the head 8 and fixing the operating shaft 5 to the cover plate 4, an E ring 22 for preventing the operating shaft 5 from coming off from the mounting plate 7, etc. It consists of
