DOOR OPENING/CLOSING DEVICE

摘要

The disclosed door opening/closing device is provided with: a brushless motor (22) that has a magnetic position-sensing element; a controller (23) that controls the brushless motor (22) in accordance with a signal outputted from the magnetic position-sensing element; a direct-operation mechanism (14) that has a drive pulley (26) that is rotated by the brushless motor (22), an idler pulley (27) that can rotate about an axis parallel to the rotational axis of the drive pulley (26), and a belt (28) wrapped around the drive pulley (26) and the idler pulley (27); and a coupling mechanism (16) that attaches to the belt (28) and couples the movement of the door (3) to the belt (28). The direct-operation mechanism (14) is set such that the drive pulley (26) rotates multiple times while the coupling mechanism (16) moves in one direction in conjunction with the belt (28).
