A centrifugal clutch is provided with a clutch housing, a clutch boss, a plate group, a pressure plate, a roller retainer, a disc spring, a pressing body and a clutch release mechanism. The pressure plate is displaced on one side in the direction of an axis line and configured to directly or indirectly press the plate group and transition the same into a pressed-contact state. The disc spring extends in a direction of being inclined to the direction of the axis line from a first end portion toward a second end portion in a centrifugal direction. The first end portion of the disc spring is directly or indirectly fixed to the clutch housing. The second end portion of the disc spring directly or indirectly biases the roller retainer toward the plate group.
