ABSTRACT:
A friction clutch mounted in a transmission case (25) or the like and connected between a drive shaft (14) for receiving engine power and a driven shaft (15) for receiving power from the drive shaft and transmitting the power to a power takeoff shaft (11). The friction clutch includes a first sleeve (17) connected to the drive shaft, a second sleeve (16) connected to the driven shaft, friction disks (18, 19) disposed between the first sleeve and the second sleeve, the friction disks being switchable between a clutch engaging state to enable power transmission between the first sleeve and the second sleeve, and a clutch disengaging state to disable the power transmission, and a clutch piston (20) movable between a first position to place the friction disks in the clutch engaging state, and a second position to place the friction disks in the clutch disengaging state. The friction clutch further includes a brake mechanism (B) for braking rotation of the driven shaft when the friction disks are in the clutch disengaging state. The brake mechanism includes a first braking member (26) operatively connected to the clutch piston, and a second braking member (24) for contacting the first braking member when the clutch piston is moved to the second position. The second braking member is rotatable through a predetermined range with the first braking member.
