Title
(EN) CENTRIFUGAL CLUTCH
Abstract
(EN) Provided is a centrifugal clutch that is capable of either reducing an assist thrust or holding an assist thrust constant even when a clutch shoe is worn down. This centrifugal clutch 200 is provided with a drive plate 210 that is rotary-driven by a driving force of an engine. The drive plate 210 is provided with pivot support pins 214 and plate-side cam bodies 218. The pivot support pins 214 each pivotably support a clutch weight 230 by being fitted in an oblong-shaped pin slide hole 231 formed in the clutch weight 230. The plate-side cam bodies 218 are each formed of a cylindrical roller and are in contact with a weight-side cam body 235 of the clutch weight 230. The weight-side cam body 235 is formed to have a curved surface that results in the same cam angle, before and after wear of a clutch shoe 233 proceeds, when the clutch shoe 233 comes into contact with a cylindrical surface of an outer clutch sleeve 240.
