PURPOSE: To provide a small and inexpensive device capable of smoothly opening and closing the double-leafed door of a power supply device such as a distribution panel automatically. CONSTITUTION: A linear motor 25 is mounted on the top plate of the enclosure 23 of a distribution panel via a turntable 30, and one end of a rod 28 reciprocated on the operation of a reversible motor 26 of the motor 25 via a linear head 27 is connected to a door 13 via a pin 34. Also, the motor 26 is driven in a forward direction to move the rod 28 unidirectionally. The door 13 is thereby turned about a hinge 21 and opened. In this case, the motor 25 turns for the top plate, and a relative angle between the rod 28 and the door 13 changes. Thus, an excessive force does not act on the motor 25 and the rod 28, thereby allowing the door 13 to be smoothly opened and closed with a small drive force. |
