Abstract:
A canceling structure of a combination switch rotatably holding a swing block for supporting a control lever on a fixing side, in which when the control lever is rotated from a neutral position, a cancel cam moves into the path of a cancel pin with the rotation of the swing block, and the cancel cam biases the swing block with the movement of the cancel pin in the opposite direction from the operating direction of the control lever, thereby returning the control lever to the neutral position, wherein:said cancel cam comprises a shaft to be guided by a long hole provided on the fixing side in parallel with the direction to move into the path of said cancel pin; pressure contact surfaces are provided at positions on the peripheral surface of the shaft, closer to a steering shaft than to said control lever; and when said cancel pin moves in the same direction as the operating direction of the control lever, the end thereof is pushed by the cancel pin, and allowed to rotate around said shaft; an elastic contact material having pressure surfaces that can be brought into contact with said pressure contact surfaces of the cancel cam is biased along a guide in the moving direction of said cancel cam; and when the cancel cam rotates, the side end of said pressure contact surface is pushed by said pressure surface of the elastic contact material, and when released from the cancel pin, the cancel pin returns to a position before rotation by the pressure from the elastic contact material.
