Patent ID: 7038580

Claim:
A turn signal switch device comprising a housing having a cam surface, an operating lever rotatably supported to the housing, a driving unit for maintaining the operating lever to be in a neutral position and an operating position in cooperation with the cam, a first lever for rotating while abutting on a canceling protrusion of a handle, a first elastic member for elastically forcing the first lever toward a rotation orbit of the canceling protrusion, and a second lever for returning the operating lever from the operating position to the neutral position by interlocking with the rotation of the first lever, wherein the first lever recedes outside the rotation orbit of the canceling protrusion against the elastic force of the first elastic member by the operating lever when the operating lever is in the neutral position, and the first lever enters the rotation orbit of the canceling protrusion by the force applied by the first elastic member when the operating lever is in the operating position, wherein first and second shafts are formed in the housing, wherein the first lever is provided in the first shaft to be rotatable, and to proceed to and recede from the rotation orbit of the canceling protrusion, wherein the second lever is rotatably provided in the second shaft, wherein the first lever and the second lever are rotatably connected to each other, wherein the second elastic member is provided in the housing together with the first elastic member, and wherein, when the operating lever is in the neutral position, the first lever is maintained in the rotation neutral position by the first elastic member, and the second lever is maintained in the rotation neutral position by the second elastic member.
