PURPOSE:To make it possible to cancell winkering of motor cycle or the like at a suitable time, by providing a handle swing angle sensor with a switch whose swing angle is zero and with a set value based on the relation between a car speed, a swing angle and a traveled distance. CONSTITUTION:When a winker switch 5 is connected to any one of contacts 5a, 5b, transistors 8, 50 are made off, and then when cornering is started with this state, a handle swing angle results in to turn off a switch 24, then a transistor 43 is made conductive in accordance with the degree of the swing angle to make 46 off, a condenser 45 is charged in proportion to the traveled distance during the cornering and the degree of the swing angle, and the electric potential V1 is gradually lowered to make the output of a differential amplifir 53 to be L. When the cornering is terminated, the switch 24 is turned on, then the transistor 46 is turned on to discharge the condenser 45, the output of the differential amplifier 53 is changed to H, and a solenoid 6 is excited by its differential signal to cause the switch 5 to be at the neutral position, that is, the winkering is cancelled. |
