Turn signal switch device

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 surface, a first lever rotating while abutting on a canceling protrusion of a handle, an 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 elastic member by the operating lever when the operating lever is in the neutral position, and the first lever enter the rotation orbit of the canceling protrusion by the force applied by the elastic member when the operating lever is in the operating position,

• wherein an intermediate support member is provided in the housing,
• wherein an opening and first and second shafts are formed in the intermediate support member,
• wherein, in a state where the cam portion protruding from the first lever, passes through and is inserted into the opening on one surface of the intermediate support member, the first lever is axially supported to the first shaft to rotate and slide, and a connecting pin protruding from the second lever is connected to the first lever, such that the first lever can rotate and slide with respect to the connecting pin,
• wherein the second lever is rotatably and axially supported to the second shaft,
• wherein the holder having the cam portion driven by the operating lever, is arranged on the other surface of the intermediate support member, and
• wherein the cam portion of the holder is engaged with the cam portion of the first lever passing through and is inserted into the opening.
