CENTRIFUGAL CLUTCH DEVICE

WIPO Patent Application WO/2011/093379

A1

Disclosed is a centrifugal clutch device with a simple structure which can inhibit clutch squeal and reduce manufacturing costs. The centrifugal clutch device is equipped with: a drive plate (4); a clutch means (5) which is mounted on the drive plate (4), and which can swing on the outer diameter side of the drive plate (4) when centrifugal force is applied; an output housing (6); and a friction material (5a) which is bonded to the surface of the clutch means (5) which faces the surface of the inner peripheral wall of the output housing (6) and which comes into contact with the surface of the inner wall when the clutch means (5) is swung by centrifugal force, rotating the output housing (6) by transmitting the drive force from a drive means thereto. The centrifugal clutch device is provided with: a groove (6c) which is formed in the inner peripheral wall of the output housing (6); and a tension member (12) which is formed from a ring-shaped member which can be fitted in the groove (6c), and which is mounted in the groove (6c) so that the diameter of said tension member (12) is stretched by being fitted in the groove, impelling the tension member (12) to the outer diameter of the groove (6c).
