PROBLEM TO BE SOLVED: To provide a switch mechanism capable of surely returning a switch to a reference position by reversely turning a rotor after the rotor is turned beyond a fixed angle. SOLUTION: A pair of projection parts 60 are projectingly formed axially on a sleeve 58 turning together with a steering wheel, and when a cancel lever 42 is in a protrusive state, the cancel lever 42 is situated between the pair of projection parts 60 along the turning direction of the sleeve 58. When the sleeve 58 turns together with the steering wheel, one projection part 60 presses an end part of the cancel lever 42 in the opposite direction to the turning direction and thereby rocks the cancel lever 42, and when the steering wheel is reversely turned. the other projection part 60 nearest to the end part of the cancel lever 42 presses the end part of the cancel lever 42 in the opposite direction to the reversely turning direction.
