Claims

[Scope of utility model registration request]

A plurality of inwardly concave transfer surfaces are formed on the wall surface that has a space on the inner circumferential side and defines the space, and a roller that functions as an impala eight is placed in the recess defined by each transfer surface with respect to the transfer surface. In a variable speed dynamic damper provided at the rolling element 1, a rigid metal belt that is always in close contact with the rolling surface during rolling is placed between the rollers and the rolling surface. A pneumatic speed type dynamic damper characterized in that one end of a belt is fixed to a roller and the other end is fixed to a transfer surface.
