Abstract
The clutch device includes, a right pressure flange that brings clutch discs provided on a clutch outer and clutch plates provided on a clutch inner into pressure contact with one another. A pressure ring that moves the right pressure flange with an external force and a clutch spring transmits the force toward a clutch connected position, from the pressure ring to the right pressure flange. Further, a return spring between the clutch inner and the right pressure flange urges the right pressure flange toward a clutch disconnected position. The clutch spring and the return spring are disposed parallel to a clutch axial direction, their respective positions overlapping each other in the clutch axial direction.
