VEHICLE TURN SIGNAL SWITCH DEVICE

Disclosed is a vehicle turn signal switch device whereby the production of knocking sounds by a cancellation pin (42) when a steering wheel (11) is turned in the direction of a turn signal is suppressed. A turn signal switch (16) comprises a fixed member (21) and a movable plate (22. The cancellation pin (42), which is supported by the fixed member (21) and the movable plate (22) such that the cancellation pin can swing and move forward and backward relative to a cancellation cam (41), comprises a sliding-contact surface (51) that is in sliding contact with the fixed member (21). The cancellation pin (42) is biased by a return spring (45) in the direction (A1) of the cancellation cam (41) and in the direction (A2) of the sliding contact of the sliding-contact surface (51) with the fixed member (21).
