Title:
CLUTCH HOUSING, CENTRIFUGAL CLUTCH, POWER UNIT, AND SADDLE RIDE-TYPE VEHICLE
Document Type and Number:
WIPO Patent Application WO/2006/006437
Kind Code:
A1
Abstract:
A clutch housing, a centrifugal clutch, a power unit, and a saddle ride-type vehicle, where component groups arranged in the rotation axis direction of the clutch housing can be made compact. The clutch housing has a housing body (73) with a disk-like wall section (91) continuously formed outward (Y1) in the radial direction (Y) of a boss section (74). The disk-like wall section (91) has a first wall section (91A) formed inward (Y2) in the radial direction (Y) and projecting from the boss section (74) toward one side (X1) in the rotating axis direction (X) and has a second wall section (91B) formed more outward (Y2) in the radial direction (Y) than the first wall section (91A) and inclined toward the other side (X2) in the rotation axis direction (X). A recessed inner surface formed on the other side (X2) in the rotation axis direction (X) of the first and second wall sections (91A, 91B) functions as a support section (92) for movably supporting a weight. A cam surface (102) is integrally formed on an inclined inner surface positioned outward (Y2) in the radial direction (Y) of the support section (92), and the cam surface (102) pushes the weight in the direction of a first clutch plate when the weight is moved by a centrifugal force.
