ABSTRACT:
A turn signal switch device capable of setting angles (release angles) in case a first lever member deviates from an outer peripheral face of a canceling projection and advances into a rotational locus at the time of right-turn operation and left-turn operation to the same angle is provided. A bent portion that is bent toward a rotational locus of a canceling projection is formed on the side of a free end of a first arm portion that protrudes linearly from a winding portion of a torsion coil spring, and when a distal end of a first lever member is dragged by the rotation of the canceling projection, and rotates in a direction away from the winding portion of the torsion coil spring, a resilient force is given to the first lever member from the bent portion of the first arm portion and a distal end on the side of the free end.
