A damper for controlling the movement of a first member with respect to a second member including an arcuate surface on one of the members which engages the outer peripheral rim of an annular damping member rotatably mounted to the other member. The annular damping member preferably is made of a compressible material, and in one embodiment is made of an open-celled urethane foam. The annular damping member is mounted on an axle positioned to locate the annular damping member in compressible engagement with the arcuate surface such that the arcuate surface engages the outer peripheral rim of the annular damping member as the two members move with respect to one another to provide a controlled damping action for the first member peripheral rim engaging the arcuate surface with a predetermined force to provide a controlled resistance force to the movement of the door.
