Zusammenfassung:	PURPOSE:To prevent the alarm sound of a direction indicating device from being drowned by the sound of an acoustic device by providing a sound volume increasing means for increasing the sound volume of the alarm sound at the operated time of the acoustic device mounted to a vehicle. CONSTITUTION:When the main switch 28a of an acoustic device is turned on, a switch 28b interlocked with the main switch 28a is also turned on, so that a current flows to the circuit of a buzzer 22, a volume 26b and the switch 28b. The total resistance value of the lower reaches side (earth side) of the buzzer 22 is thereby reduced, so that the current flowing in the buzzer 22 is increased, and the sound volume of the buzzer 22 is also increased. The alarm sound of the buzzer 22 is thereby prevented from being drowned by the sound of the acoustic device in operation. Moreover, when the volume 26b increases the volume 26a and sound volume of the acoustic device, the sound volume of the buzzer 22 is also increased correspondingly.
