摘要： A turning direction indicator device includes an actuator that rotates by an operation of the operating lever, a cam body that shifts in a rearward direction approaching a cancel cam. The cam body is rotatable about a rotation axis, and shifts in the rearward direction when the actuator rotates. The cam body includes a rear wall surface opposite to the cancel cam. The rear wall surface has two end parts symmetrical to each other with respect to the longitudinal axis. A spring elastically contacts the end parts to urge the cam body in the rearward direction. The spring also urges the cam body in a rotating direction about the rotation axis when the longitudinal axis of the cam body rotates. The turning direction indicator device suppresses a hitting noise produced by the cam body and a release element with such a simple structure, and operates reliably.
