To miniaturize a centrifugal clutch, and to reduce the vehicle width of a saddle type vehicle having the centrifugal clutch.

This centrifugal clutch 15 has a clutch housing 81 to which an outer plate 83 is mounted and a clutch boss 82 to which an inner plate 86 is mounted. A roller weight 88 is provided between the clutch housing 81 and an outer plate 83A disposed at the rightmost side. The clutch housing 81 has a cam surface 87 formed thereon for guiding the roller weight 88 in a direction so that the outer plate 83 and the inner plate 86 are press-fitted to each other when the roller weight 88 moves outward in the radial direction of a secondary sheave shaft 38. The pouter plate 83A has a cam surface 80 formed thereon for guiding the roller weight 88 outward in the radial direction and toward the cam surface 87 side with respective to an axial direction when the roller weight 88 moves outward in the radial direction of the secondary sheave shaft 38.
