Centrifugal clutch, and method of making same

摘要

A centrifugal clutch includes vibration isolation ring. The vibration isolation ring reduces or prevents the occurrence of squeaking noises due to the vibration of the clutch outer cover. The vibration isolation ring can be made with a large wall thickness, thereby reducing or preventing deformation of an open-end of a drum wall in the clutch outer cover. The vibration isolation ring has a cylindrical shape and is disposed so as to surround the drum wall at a position substantially corresponding to the location at which a portion of a friction material makes a sliding contact with a drum wall. An end portion of the vibration isolation ring is welded to an outer periphery of the drum wall on a side thereof which is distant from a bottom wall of the clutch outer cover.
