DAMPER FOR USE IN CLUTCH

摘要

A damper is in the form of a disk and used for the clutch including: a clutch housing in which a clutch plate is held; and a clutch gear that transmits rotary drive power to the clutch housing via the damper. A non-circular engagement hole is formed at a center portion of a disk of the damper such that an engagement projection of the clutch housing engages with the engagement hole. First cutout portions are formed in the damper on an outer side and an inner side in a clutch radial direction on a rear side on which rotary drive power from the clutch gear is applied. A minimal distance between each first cutout portion and the engagement hole is smaller than a distance between the engagement hole and an outer circumference of the disk.
