Abstract
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 chamberthrough which fluid can pass, a valve bodywhich forwardly moves from a natural state position when the valve bodyreceives fluid pressure and which can forwardly moves in the operating chamber, and a first springcapable of giving a resistance to the forward movement of the valve body. The valve mechanism can reduce a flow rate of fluid which passes through the operating chamberby a flow pathformed between the valve bodyand a peripheral wallof the operating chamber. A reducing amount of fluid can be increased as a moving distance of the valve bodywhich forwardly moves in the operating chamberis increased.
