Claims

[Claims for Utility Model Registration] 1. A casing 1, a rotating shaft 2 passing through the center of the casing 1 in the axial direction, and a rotating shaft 2 fixed in the casing 1 so as to be movable and adjustable in the axial direction, and having a tapered surface 3a on the inside. A fixed outer cylinder 3 with a bottom, and a one-way clutch 6 that opposes the fixed outer cylinder 3 through a one-way clutch 6 that releases the rotation of the rotating shaft when the door is opened and transmits the rotation of the rotating shaft when the door is closed to the rotating shaft 2. and a rotary inner cylinder 4 which is attached to the rotary inner cylinder 4 and has a tapered surface 4a on the outside corresponding to the tapered surface 3a of the fixed outer cylinder 3. A viscous fluid 10 is sealed in the gap 5 with the tapered surface 4a, and the restoring speed of the rotating shaft 2 can be adjusted by sliding the fixed outer cylinder 3 in the gap between the fixed outer cylinder 3 and the rotating inner cylinder 4. A door tick that utilizes viscous shear resistance. 2. A door utilizing viscous shear resistance as set forth in claim 1 of the utility model registration claim, in which a spring 7 is provided between the inner surface of the casing 1 and the rotating shaft 2 to provide a rotational restoring force to the rotating shaft 2 when the door is closed. check. 3. The casing 1 is attached to plate A, the rotating shaft 2 is attached to plate B, and is hinge-shaped, and the viscous shear resistance according to either claim 1 or 2 of the utility model registration claim is achieved. Check the door used.
