Abstract: Provided is a retracting device which can decrease a difference of restoring force of a tension coil spring between a retracted position and a stop position. The retracting device of the present invention includes a base 12, a slider 14 which can catch a trigger 8 and move from the stop position to the retracted position with respect to the base 12 and a tension coil spring (B) for relatively moving the slider 14 which has caught the trigger 8 from the stop position to the retracted position with respect to the base 12 to apply force for assisting the closing operation to a sliding door 1. The tension coil spring (B) is an initially-tensioned spring in which a coil closely contacts and which has initial tension in a direction in which the coil closely contacts when it is in a natural length.

Abstract: Provided is a stay which is capable of stabilizing movement of a component part used for transmitting, or not transmitting, the torque of one of a first member and a second member to the other. When a second member (12) rotates relative to a first member (11) in one direction, a cam base (36) moves away from a disk (34) in the direction of the rotation axis (C), and the second member (12) and the cam base (36) rotate relative to the first member (11) and the disk (34). When the second member (12) rotates relatively to the first member (11) in the other direction, the cam base (36) moves towards the disk (34) in the direction of the rotation axis (C), and the second member (12), the cam base (36) and disk (34) rotate relative to the first member (11) with resistance force.

Abstract: Disclosed is a door device that can ensure necessary catch function and/or assist function and give a neat impression is provided. The hinge includes a first part to be attached to a main body and a second part to be attached to a door. The door device includes a base, an arm rotatably supported on the base and a spring for applying torque to the arm in the closing direction and/or in the opening direction thereof. The base of the door device is attached to the first part of the hinge.
