ABSTRACT:
A direction-indicating device for use in a vehicle, in which at least one of engaging Portions at both end portions of a ratchet includes: a first surface, which is shoved by a cam-protruding portion located on a canceling cam, when a bracket remains pivoted to either a counterclockwise position or a clockwise position, and further the canceling cam is turned in the same direction as the bracket; a second surface, against which the cam-protruding portion scrapes when the cam-protruding portion is driven into further movement in the orientation of the bracket after passing over the first surface upon movement of the ratchet due to thrusting of the cam-protruding portion at the first surface; and, a third surface, with which the cam-protruding portion is moved into engagement when the bracket remains pivoted to either the counterclockwise position or the clockwise position while the canceling cam is turned in a direction opposite to that of the bracket, the bracket being pivoted to the neutral position because of engagement between the cam-protruding portion and the third surface. Each of the first surface through the third surface forms a different angle with a reference line which extends between a central point of the canceling cam and the neutral position of said detent mechanism.
