A clutch apparatus 100 includes a center clutch 105 and a pressure clutch 112, which hold clutch plates 104 placed facing friction plates 103 that are rotationally driven by a driving shaft. The center clutch 105 includes a center-side mating portion 108 mating with internal teeth of the clutch plate 104. In addition, the center-side mating portion 108 includes a protruding tooth 110. The pressure clutch 112 includes a pressure-side mating portion 116 mating with internal teeth of the clutch plate 104. In addition, the pressure-side mating portion 116 includes a run-off 117. The protruding tooth 110 extends over the run-off 117 of the pressure-side mating portion 116, as one of spline teeth forming the center-side mating portion 108.
