Abstract
A drive gear ( ) having integral drive teeth ( ) is rotatably mounted on a transmission shaft ( ) for transmitting power to front wheels, and a movable clutch member ( ) having integral driven teeth ( ) engageable with the drive teeth is slidably but non-rotatably mounted on the transmission shaft. A spring ( A) for biasing the movable clutch member into a direction of causing engagement of the driven teeth with the drive teeth is inserted at a part thereof into an axial bore ( ) in the clutch member. A piston ( ) is slidably fitted in a cylinder member ( ) which is fixedly mounted on the transmission shaft at a radially inward location of the drive and driven teeth. The transmission shaft includes a fluid passage ( ) which applies fluid pressure to the piston such that the piston is moved so as to move the movable clutch member into a direction of causing disengagement of the driven teeth from the drive teeth. The front wheel drive clutch of this structure is small in the number of parts, is compact in its axial length, and is rich in durability.
