PURPOSE:To positively connect an external power connecting section to a power feed section, by detecting the external power connecting section in electrical contact with the power feed section, and by pushing the external power connecting section against the power feed section. CONSTITUTION:Travelling to a working place is executed by selecting a storage battery 28 at a motor feed power switching section 77 and by controlling a vehicle motor driving section 76. When a vehicle comes to the working place, then signal from a plug socket position indicating section 51 is received at a plug socket position detecting section 52, and an external power connecting section 48 is connected to a power feed section 49. When the external power connecting section 48 comes in contact with the power feed section 49, then its feed is detected by a plug socket/plug connection detecting section 50, and by the signal of a car driving control section 70, a traveling service vehicle is moved backward to the power feed section 49, and the external power connecting section 48 is perfectly connected to the power feed section 49. When the external power connecting section 48 is connected to the power feed section 49, then feed from the storage battery 28 is switched to feed from the external power connecting section 48 by the motor feed power switching section 77. |
