1. A clutch device to allow or block transfer of a rotation driving force of an input shaft to an output shaft, the clutch device comprising:
a clutch center housed in a clutch housing holding a plurality of input-side rotating plates rotationally drivable by rotational driving of the input shaft, the clutch center holding a portion of a plurality of output-side rotating plates alternately arranged with the input-side rotating plates, the clutch center being rotationally drivable together with the output shaft; and
a pressure plate movable toward or away from the clutch center and rotatable with respect to the clutch center, the pressure plate being capable of pressing the input-side rotating plates and the output-side rotating plates; wherein
the pressure plate includes:
a body;
a flange extending radially outward from an outer circumferential edge of the body;
a plurality of pressure-side fitting teeth projecting in a first direction from a first direction-side surface of the flange, holding another portion of the plurality of output-side rotating plates, and being arranged in a circumferential direction, where the first direction is a direction in which the pressure plate moves toward the clutch center, and a second direction is a direction in which the pressure plate moves away from the clutch center; and
a flange-side recessed portion recessed in the first direction from a second direction-side surface of the flange and not in communication with the first direction-side surface of the flange; and

as seen in an axial direction of the output shaft, the flange-side recessed portion at least partially overlaps one of the pressure-side fitting teeth.
