Claims (1)

[Scope of utility model registration request] A pair of steering angle sensors that output pulse signals according to the amount and direction of rotation of the steering wheel, and a pair that receives signals from the steering angle sensor and allows only pulse signals in the opposite direction generated when the steering wheel is turned back to pass. When the number of pulse signals input from the gate circuit and sent when the steering wheel is turned back exceeds a preset value, a reset signal is issued and the turn signal relay is deenergized. 1. An electronic turn signal auto canceller comprising a comparison circuit for changing the set value, wherein the comparison circuit includes variable operation means for arbitrarily changing the set value.
