Title: MULTIFUNCTION SWITCH UNIT FOR VEHICLE
Abstract:
The purpose of the present invention is to provide a multi-function switch unit for a vehicle which can reduce an occurrence of noise due to a collision between parts when a return function is operated after a turn signal operation. The multi-function switch unit for a vehicle according to the present invention comprises: a housing coupled to a steering column side; a lever switch mounted to protrude from one side of the housing and rotating for a predetermined interval; a moving block disposed inside the housing, rotating together with the lever switch, and having a latch block on one side thereof; a guide bush installed on the steering column side so as to rotate together with a steering wheel; and a cancel cam for returning, to the original position, the moving block which is operated, rotated, and moved by the guide bush according to the operating state of the steering wheel. The cancel cam comprises: a cam body rotatably coupled to the housing so that one side thereof can contact an engaging block; and a buffer rib which is provided to be resilient-deformable in the cam body so as to be able to buffer an impact caused by a collision with the engaging block by contacting the engaging block before the cam body when the cam body rotates.
