Abstract
To centrifugal clutch with reduced size, which facilitates reduced width of a straddle type vehicle, includes a clutch housing on which an outer plate is mounted, and a clutch boss on which an inner plate is mounted. A roller weight is provided between the clutch housing and a rightmost outer plate. A cam surface formed on the clutch housing guides the roller weight in a direction such that the outer plate and the inner plate are press-fitted together when the roller weight moves outward in a radial direction of a secondary sheave shaft. A cam surface formed on the rightmost outer plate guides the roller weight outward in the radial direction and toward the cam surface with respect to an axial direction when the roller weight moves outward in the radial direction of the secondary sheave shaft.
