Abstract
A turn signal apparatus for returning a turn lever to its neutral position by the rotation of a steering shaft in a return direction as the turn lever is rotated at the time of making a change in the forward direction of a vehicle. A ratchet which is brought into a rotating path of a cancellation cam of the steering shaft by the manipulation of a turn lever is interposed between the turn lever and the steering shaft. The ratchet and a pair of arms are oppositely urged by an urging spring. The ratchet which is rotated by the cancellation cam at the time of rotation of the steering shaft in the returning direction imparts its rotating force to the turn lever via one of the arms urged by the urging spring. Since the arm boosts the rotating force of the ratchet in transmitting the rotating force to the turn lever, a steering shaft rotating force required for returning the turn lever is minimized.
