Abstract

In a clutch device wherein a plurality of clutch plates are relatively non-rotatably engaged with a clutch outer, a plurality of clutch disks disposed alternately with the clutch plates are relatively non-rotatably engaged with a clutch inner, and an end plate disposed so that the clutch plates and the clutch disks are disposed between itself and a piston slidably fitted in the clutch outer is relatively non-rotatably and axially movably supported on the clutch outer in the manner of being restricted in movement toward one end side in the axial direction, to prevent the clutch inner from coming out of position at the time of assembling the clutch device into position, thereby to enhance workability in the assembling operation, and to prevent the clutch inner from generating a collision sound by colliding against other member than the component members of the clutch device when the clutch is disengaged.
