Problems solved by technology

But on the other hand, because must increase two parts of shaft 204 and fall-off prevention part 205, the number of parts is increased, and because very small fall-off prevention part 205 such as washer must be installed on one end of shaft 204 and occurred. Problems that reduce assembly efficiency

Abstract

The invention provides a turn signal switch device. Even if a control lever driven force is set with required strength, there's nothing to worry about the control lever base portion desquamation from a holder, assembly efficiency is fine and component amount can be reduced. When the turn signal switch device is assembled, a base portion (3a) of the control lever (3) is inserted into an opening (9a) of the holder (9), and a shaft (21) is inserted into a shaft hole (3c) of the base portion (3a) and a bearing hole (9e) of a side plate (9d) of the holder (9) so as to be retained. Then, the control lever (3) and the holder (9) are rotatably connected. Further, a ring-shaped groove (21b) is provided at the end of the shaft (21) opposite a head (21a), and a flexible engagement piece (9g) is provided on the side plate (9d) of the holder (9), the flexible engagement piece (9g) extending inward in the radial direction of the bearing hole (9e) so as to be engaged with the ring-shaped concave groove (21b). The flexible engagement piece (9g) is pressed and deflected by the leading end of the shaft (21) in the middle of attachment. Further, when the leading end passes through the flexible engagement piece (9g), the shaft (21) is snapped to the holder (9).

Description

technical field [0001] The present invention relates to a turn signal switch device attached to a steering column of an automobile and used as a direction indicator. Background technique [0002] In the turn signal switch device of an automobile, the base of the operating lever is pivotally supported by a bracket and can be tilted along a plane, and the bracket is pivotally supported by a housing fixed to a steering column, etc., so that the bracket and the operating lever are integrated and can be tilted along a plane The other plane, which is roughly orthogonal to the above-mentioned one plane, is poured. Then, if the rod portion of the operating lever is tilted from the neutral position to any one of the left and right direction indication positions along the above-mentioned other planes, the left turn or right turn light will flash. In addition, if the rod portion of the operating lever is tilted along the above-mentioned one plane, the light beam switching or overtakin...
