Abstract
A clutch drum is engaged to the rear part of a carrier of a center differential device. A clutch piston, which is rotated together with the rear drive shaft while allowing it to retractively move in a direction along a rear drive shaft, is provided within the clutch drum. Pinion shafts are protruded from the rear end face of the carrier to form protruded parts, which are confronted with the front end face of the clutch piston. A cam part, which is in sliding contact with the protruded parts, is formed on the front end of the clutch piston. When the carrier and the rear drive shaft relatively rotate, the protruded parts retractively move the clutch piston along cam crests of the cam part to press a clutch mechanism.
