A motor vehicle turn signal cancelling device operated by a turn signal cancelling member projecting from the steering wheel includes a frame structure and a mounting member attached thereto. A fixture having a central portion positioned between oppositely extending first and second arms is pivotally mounted to the mounting member at the central portion to move the first and second arms into the path of movement of the cancelling member. The device further includes a turn signal activating lever pivotally mounted between its ends to the frame structure. A cancellation arm is pivotally mounted to the mounting member and defines a slot near its distal end. An engagement post associated with the lever is received in the slot defined in the cancellation arm. The engagement post and the slot are positioned between the pivotal axis of the turn signal activating lever and the pivotal axis of the cancellation arm.
