PURPOSE:To prevent an excitation device from being left as energized due to the forgetting of the disconnection of a power source, etc., by energizing an electric vibrator based on the electrical signal of a signal generating means when energizing indication is issued, and de-energizing the electric vibrator by detecting the absence of a person by a person detecting means. CONSTITUTION:A control means 1, a Drv1, and RL1-RL4 which energize the electric vibrator based on the electrical signal of the signal generating means when the energizing indication is issued from indicating means SW1-SW4, and de-energize the electric vibrator when absence of the person is detected by the person detecting means 1-3, are provided. Therefore, the electric vibrator provided in the seat is de-energized when no person occupies the seat. In such a way, it is possible to prevent the device from being left as energized even due to the forgetting of the disconnection of the power source, or after the person leaves the seat. |
