Abstract:
Provided is a centrifugal clutch having a simple configuration and configured so that a clutch capacity can be increased. A centrifugal clutch ( 200 ) includes a drive plate ( 210 ) to be directly rotatably driven by drive force of an engine. The drive plate ( 210 ) includes swing support pins ( 214 ) and protrusions ( 218 ). The swing support pin ( 214 ) is fitted in a pin slide hole ( 231 ) formed at a clutch weight ( 230 ), and swingably supports the clutch weight ( 230 ). The protrusion ( 218 ) includes a cylindrical roller, and contacts a driven portion ( 235 ) of the clutch weight ( 230 ). The pin slide hole ( 231 ) is formed in a long hole shape allowing the clutch weight ( 230 ) to displace backward in a rotary drive direction of the drive plate ( 210 ). The driven portion ( 235 ) is formed to extend inclined outward to a rear side in the rotary drive direction of the drive plate ( 210 ).

Claim (Index 1):
A centrifugal clutch comprising:\n a drive plate to be rotatably driven together with a driven pulley in response to drive force of an engine; a clutch outer positioned outside the drive plate and having a cylindrical surface provided concentrically with the drive plate; a clutch weight having a clutch shoe formed to extend along a circumferential direction of the drive plate and facing a cylindrical surface of the clutch outer; a protrusion provided to protrude toward the clutch weight on the drive plate; and a driven portion provided at the clutch weight, wherein one end side of the clutch weight in the circumferential direction is rotatably attached onto the drive plate via a swing support pin and a pin slide hole, the other end side of the clutch weight in the circumferential direction is displaced toward a cylindrical surface side of the clutch outer, the clutch weight climbs on the protrusion upon displacement of the other end side of the clutch weight, the swing support pin is provided at one of the drive plate or the clutch weight, and is formed to extend toward the other one of the drive plate or the clutch weight, the pin slide hole is provided at the other one of the drive plate or the clutch weight, and is formed in a long hole shape allowing one end side of the clutch weight to displace backward in a rotary drive direction of the drive plate, and the swing support pin is slidably fitted in the pin slide hole.
