A centrifugal clutch which can transmit rotation of a primary shaft on the input side to a secondary shaft on the output side joining them by utilizing a centrifugal force which increases with the increase of the rotation of the primary shaft. A shoe divided into plural segments is arranged around a rotor which is fixed to the primary shaft; arcuate dents are made on the inside of the shoe and the outside of the rotor in such a way that each of the dents on both sides is placed face-to-face in pairs and pillars can be put between their couples. The pillars are made of an elastic material and around the shoe is a spring, so that the shoe always clamped together to the rotor with the pillars being put between them. A cylinder to which the secondary shaft is fixed encloses the shoe. Thus, when the primary shaft begins to rotate accompanying the rotor, each segment of the shoe gradually comes apart from the shaft by a centrifugal force, which results in pressing them against the inside of the cylinder so strongly as to cause the secondary shaft to rotate in association with the primary shaft.
