Abstract

A vibration absorber is provided which is mounted in an annular space housing a spring of a damper, wherein accompanying rotational fluctuation of a drive source, when a first plate connected to the drive source and a second plate connected to a transmission rotate relative to each other while elastically deforming a spring, an arm part extending radially outward from a driven plate swings in the interior of an annular space, and grease packed in the annular space is compressed by the arm part and pushed inward in the radial direction, but since this grease is guided in the peripheral direction by a flow-aligning projection provided on either one of the driven plate and the seal plate and projecting toward the other, and is prevented from being concentrated in part of a seal member provided on the inner peripheral part of the seal plate and sealing the annular space.
