Description of the Related Art For example, in the case of a lid or a door which can be opened and closed, a damping device is provided to prevent sudden opening and closing due to acceleration. However, since they used a piston mechanism as invented in Japanese Utility Model Publication No. 59-26051, further miniaturization was required. As a result, the applicant has developed a damping device that allows viscous fluid to pass through with different resistances depending on the direction of rotation.
