<Operation> Next, the operation of the above embodiment will be described.

Now, when the turn signal lever 16 is not operated and is in the neutral state, since the detection signal is not output from the detection unit, the control pulse generation unit outputs no control pulse to both the transistors 22 and 23. Both transistors 22 and 23 remain off. When both the transistors 22 and 23 are off, the capacitor 2
No charging current flows through 9.

Then, for example, the turn signal lever 16
When is operated to the left, the detection section outputs a left side detection signal to the microcomputer 26, and the left side detection signal causes the control pulse generation section to output a control pulse to the base of the transistor 22. 22 repeats turning on and off at a constant cycle. As a result, the power supply to the left front and left rear blinker lamps 18F, 18R is intermittently started, the left front and left rear blinker lamps 18F, 18R start blinking, and the left front and left rear blinker lamps 18F, 18R are started.

This discharge current causes the second relay to self-hold, and the normally open contact 34a and the normally closed contact 34b of the second relay continue to be turned on, and the left accessory 40 is supplied with power even when the transistor 22 is off. The path is held closed and the left accessory 40 is continuously energized.

Thus, while the transistor 22 is repeatedly turned on and off, the left accessory 40 is continuously energized, and the left accessory 40 starts its operation in conjunction with the start of blinking the left front and left rear blinker lamps 18F, 18R. However, while the left front and left rear blinker lamps 18F and 18R repeatedly blink, the left accessory 40 is continuously supplied with a constant voltage from the battery and continues to operate.

The right front and left rear blinker lamps 1 when the turn signal lever 16 is operated rightward.

Therefore, according to the above-described embodiment, the existing left and right turn signal lamps 18F, 18R and 19 are used.
When the left and right accessories 40 and 42 interlocking with these are added to the F and 19R, the microcomputer 26 for controlling each of the turn signal lamps 18F, 18R, 19F and 19R does not require any design change, and the
Or diodes 31, 36, 37, 45, 46, relays, etc. are all that is required, and the blinker lamps 18F, 18R,
The control of the left and right accessories 40, 42 associated with the blinking of 19F, 19R can be realized by a device of low cost and simple structure.

In the embodiment described above, the opening / closing part is constituted by the normally open contacts 33a, 34a of the relay, and the holding part 4

The holding section and the holding section are not limited to these, and the opening / closing section is composed of switching means such as a switching element, and the holding section has a circuit structure such as an operational amplifier which holds the switching means in a closed state. It doesn't matter.

Further, in the above embodiment, the left and right turn signal lamps 18F, 18R and 19F, 19R are kept blinking until the detection unit detects the return of the steering wheel 5 to the neutral position. However, the left and right turn signal lamps 18F and 18R for a predetermined time counted by a timer, for example.
Alternatively, 19F and 19R may be kept blinking. In this case, as the count time of the timer, an average time required for returning the steering wheel 5 to the neutral position after the steering handle 5 is operated in the turn direction is obtained in advance, and the average time is counted by the timer. Is desirable.
