PROBLEM TO BE SOLVED: To provide an opening/closing door which provides an assistant force to a door-opening/closing force of the door-operator so that the door can be opened/closed by applying a small operating force, is free from a fear of erroneous operation because the door is opened/closed in the same operating manner as in a conventional manual opening/closing door, is much improved in operability, prevents accidents such as confinement of the door-operator by the door or collision with the door, and is high in safety. SOLUTION: The door which partitions a space and moves in an openable manner, is comprised of a driving source for thrusting the door in an opening/ closing direction, and a means for controlling movement of the driving source in a direction in which the operator desires to move the door. According to the opening/closing door, the door itself is not automatically movable, but the driving source is operated so as to provide the assistant force to the opening/ closing force of the door-operator. |
