摘要： The present invention provides a rotary damper in which both yields and braking characteristics can be enhanced. The rotary damper of the invention includes a valve mechanism which comprises an operating chamber 7 through which fluid can pass, a valve body 8 which forwardly moves from a natural state position when the valve body 8 receives fluid pressure and which can forwardly moves in the operating chamber 7, and a first spring 9 capable of giving a resistance to the forward movement of the valve body 8. The valve mechanism can reduce a flow rate of fluid which passes through the operating chamber 7 by a flow path 14 formed between the valve body 8 and a peripheral wall 7a of the operating chamber 7. A reducing amount of fluid can be increased as a moving distance of the valve body 8 which forwardly moves in the operating chamber 7 is increased.

摘要： A rotary damper is provided which can include a valve (6) which automatically varies a flow rate of a viscous fluid passing through fluid passages (5a, 5b) in correspondence with variation in load. The valve (6) comprises a leaf spring. The flow rate-adjusting portion (6g) constituting the valve (6) is provided so as not to close the fluid passages (5a, 5b) when no load is applied and bends so that its one surface side projects when no load is applied and becomes deformed in a direction in which the fluid passage (5b) is closed when receiving pressure of the viscous fluid on its one surface side. The flow rate of the viscous fluid passing through the fluid passage (5b) is adjusted depending on a degree of deformation of the flow rate-adjusting portion (6g) corresponding to magnitude of pressure of the viscous fluid applied to one surface side of the flow rate-adjusting portion (6g). The flow rate-adjusting portion (6g), when receiving pressure of the viscous fluid on its other surface side, keeps the fluid passages (5a, 5b) open at all times.
