A clutch drum is configured to reduce the weight of a clutch drum while keeping the mechanical losses of the clutch drum in check. The clutched drum houses several clutch plates and has a cylindrical part and a plurality of the teeth that are arranged circumferentially around the inside of the cylindrical part and extend in the axial direction. The teeth have tooth cusps and tooth flanks on both rotational-direction sides. Bottom lands are formed on the inside surface of the cylindrical part between the teeth in the axial direction. The outside recesses are formed on the portions of the outside surface of the cylindrical part that correspond to the teeth and the inside recesses are formed on the inside surfaces of the teeth
