A centrifugal clutch 200 includes a first drive plate 210 rotationally driven directly by a driving force of an engine and a second drive plate 220 frictionally in contact with the first drive plate 210. The first drive plate 210 includes a bulging body 215 on a supporting portion 214 bulging toward the second drive plate 220. The second drive plate 220 is rotationally driven together with the first drive plate 210 while allowing rotational displacement relative to the first drive plate and includes clutch weights 230. The bulging body 215 is made of a cylindrical roller. The clutch weight 230 is formed with a driven portion 232. The driven portion 232 has a pressing body 232a in contact with the bulging body 215. The pressing body 232a obliquely extends rearwardly and outwardly in a rotational drive direction of the first drive plate 210.
