Rotary damper

Described is a rotary damper comprising a partition wall to partition space formed between a rotor and a housing to house said rotor and to form a fluid chamber to be fluid-filled; and a vane to be disposed in said fluid chamber; and a plug to close an opening of said housing; wherein said plug has a flange to be used for mounting which protrudes from an outer circumferential surface of said plug and a stepped portion to enable part of a roller caulking an edge of said opening of said housing to revolve and travel along a peripheral edge of said housing so that said plug having said flange is coupled to said housing by caulking an edge of said opening of said housing.

Rotary damper and method for manufacturing rotary damper

A rotary damper is provided which can include a valve () which automatically varies a flow rate of a viscous fluid passing through fluid passages (a,b) in correspondence with variation in load. The valve () comprises a leaf spring. The flow rate-adjusting portion (g) constituting the valve () is provided so as not to close the fluid passages (a,b) 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 (b) 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 (b) is adjusted depending on a degree of deformation of the flow rate-adjusting portion (g) corresponding to magnitude of pressure of the viscous fluid applied to one surface side of the flow rate-adjusting portion (g). The flow rate-adjusting portion (g), when receiving pressure of the viscous fluid on its other surface side, keeps the fluid passages (a,b) open at all times.
