Patent ID: 8552319

Claim:
A turning direction indicator device used with a cancel cam rotating in accordance with a rotation of a steering shaft, the turning direction indicator device comprising: an operating lever; an actuator that rotates by an operation of the operating lever so as to be positioned at a neutral position and a first operational position; a switch contact part that performs electrical connection and disconnection and outputs a turning direction indicating signal in accordance with a rotation of the actuator; a cam body that is rotatable about a rotation axis, and that shifts in a rearward direction approaching the cancel cam when the actuator rotates from the neutral position to the first operational position; an urging spring that urges the cam body; and a release element that includes a coupling part, a first release projecting part projecting from the coupling part in the rearward direction, and a second release projecting part projecting from the coupling part in the rearward direction, the release element rotating together with the actuator, wherein the cam body includes: a base part; a rear cam part that projects from the base part in a direction approaching the cancel cam along a longitudinal axis; a front cam part that projects from the base part in a direction opposite to the direction in which the front cam part projects from the base part along the longitudinal axis; and a rear wall surface that has a first end part and a second end part which are symmetrical to each other with respect to the longitudinal axis, and that opens in a direction away from the cancel cam, the front cam part of the cam body is located between the first release projecting part and the second release projecting part of the release element, the urging spring is configured to: elastically contact the first end part and the second end part of the rear wall surface of the cam body to urge the cam body in the rearward direction, and urge the cam body in a rotating direction about the rotation axis when the longitudinal axis of the cam body rotates about the rotation axis, and the rear wall surface is provided with a recess between the first end part and the second end part, and the recess has a bottom located away from the urging spring.
