Claims

[Claims for Utility Model Registration] (1) A shaft that passes through a door, is rotatably supported with respect to the door, and has a handle fixed to each end, and a torsion wound around the shaft. a coil spring, a stopper fixed to the door and located around the torsion coil spring, and a core arranged concentrically with the stopper and connected to the shaft so as to rotate together with the shaft. , the core and the stopper are formed in a substantially semi-cylindrical shape, and each end of the core in the circumferential direction constitutes a first and second engaging surface with which each end of the spring comes into pressure contact, respectively. Each end of the stopper in the circumferential direction also constitutes a first and a first stop surface to which each end of the spring is pressed, respectively, and when the handle is in a neutral position, one end of the spring is in contact with the stop surface. The spring is in pressure contact with a first stop surface of the stopper and a first engagement surface of the core, and the other end of the spring is in pressure contact with a second stop surface of the stopper and two engagement surfaces of the core. Due to the rotation in the direction, one end of the spring rotates while being in pressure contact with the first engaging surface of the core, and separates from the first stop surface of the stopper, and the other end of the spring contacts the second stop of the stopper. The spring stops while being pressed against the surface, and is separated from the second engaging surface of the core, and as the handle rotates in the other direction, the other end of the spring rotates while being pressed against the second engaging surface of the core. and is separated from the second stop surface of the stopper, one end of the spring stops while contacting the first stop surface of the stopper, and is spaced apart from the first engagement surface of the core. and door handle neutral position return device. (2) The handle neutral position return device according to claim 1, wherein the torsion coil spring, stopper, and core are arranged outside the door.
