The band is wound around an outer peripheral portion of the clutch drum, and is made of carbon fiber reinforced plastic. The spline large-diameter portions are provided with a protrusion protruding outward in the radial direction. The band includes a recessed portion with which the protrusion is engaged. The recessed portion is provided at a position at which the recessed portion faces the protrusion.
