Claims

[Scope of utility model registration request]

In a torsional vibration absorption damper in which a weight is rotatably housed in a housing and a viscous liquid is sealed in the housing in order to absorb torsional vibration generated in a crankshaft for an internal combustion engine, at least the inner surface of the housing or the outer surface of the weight is used. The torsional vibration absorbing damper is characterized in that a concavo-convex portion is formed that extends obliquely with respect to the direction of relative motion between the housing and the weight.
