ABSTRACT:
In a turn signal control device for a vehicle having an automatic canceling function, a switch operating element is carried on a pivot shaft mounted in a fixed switch case so that the switch operating element can be returned and pushed-in between a returned position and a pushed-in position. The switch operating element is swingable at the returned position between a neutral position and a left-turn indicating position and a right-turn indicating position. The switch operating element is pushed-in to the pushed-in position by push-in operation at the returned position. The switch operating element is resiliently urged toward the neutral position and there turned position. A winker switch is operatively connected to the switch operating element so as to break the connection of a left-turn indicating means or a right-turn indicating means to a flasher unit in response to push-in of the switch operating element to the pushed-in position. Thus, a switch and an electric circuit for manual canceling are not required to improve reliability.
