# Clutch device, motorcycle, and method for producing pressure plate

## Abstract

A clutch device includes a pressure plate movable toward or away from a clutch center and rotatable with respect to the clutch center. The pressure plate includes a flange extending radially outward from an outer circumferential edge of a body, pressure-side fitting teeth projecting in a first direction from a front surface of the flange, holding input-side rotating plates and a portion of output-side rotating plates being arranged in a circumferential direction, a body-side recessed portion recessed in the first direction from a second direction-side surface of the body, and a flange-side recessed portion recessed in the first direction from a back surface of the flange. As seen in an axial direction of an output shaft, the flange-side recessed portion at least partially overlaps one of the pressure-side fitting teeth.
