摘要： PROBLEM TO BE SOLVED: To provide an assistance to door opening and closing operations by using manpower and auxiliary devices for opening and closing the door, which can be independently set during opening and closing of the door. SOLUTION: These are auxiliary devices 9 and 10 for opening and closing a door equipped with a first torsional coil spring 12 with one end portion 12a fixed to a rotating shaft 11 rotating during opening and closing operation of the door 1 and a second torsional coil spring 13 with one end portion 13a fixed to the rotating shaft 11 wound in a reverse direction of the first torsional coil spring; the other end portion 12b of the first torsional coil spring is supported in such a manner that the first torsional coil spring is in a torsional state when the rotation angle of the rotation shaft is positioned in the first range θ1; and other end portion 13b of the second torsional coil spring is supported in a state where the second torsional coil spring is torsional when the rotation angle of the rotation shaft is located in the second range θ2.
