Claims

[Claims for Utility Model Registration] 1. A casing having a hollow chamber, a rotor and a passive shaft connected to the casing, the rotor being rotatably supported within the hollow chamber, and the passive shaft having a hollow chamber. A rotating body arranged so as to protrude outward from the chamber, and a part or all of the inside of the coil arranged so as to be in contact with the outer circumferential surface of the rotor, and one end of which is fixedly fixed to the casing. The other end is made up of a coil spring with a free end, and a lubricant with relatively strong viscosity applied to the outer peripheral surface of the rotor, and when the rotating body rotates in the direction of tightening the coil spring, A one-way rotary damper characterized in that it is provided so as to only produce a damping action. 2. The one-way low collie damper according to claim 1, wherein the coil spring is arranged such that the entire inside of the coil is in contact with the outer peripheral surface of the rotor in a normal state. 3. The coil spring according to the above-mentioned registered claim, wherein a part of the inside of the coil is in contact with the outer circumferential surface of the rotor under normal conditions, and the other inner part of the coil is arranged with a slight distance from the outer circumferential surface of the rotor. One-way rotary damper as described in scope 1. 4. The one-way rotary damper according to claim 3, wherein the inner side of the coil near the free end is arranged so as to be in contact with the outer peripheral surface of the rotor.
