Patent ID: 7361117

Claim:
A differential limiter, comprising: 1) a differential mechanism, including: i) an input member for receiving a driving torque, ii) a first output member, iii) a second output member, and iv) a differential gear for connecting the input member, the first output member and the second output member in such a manner that the input member, the first output member and the second output member differentially rotate; 2) a shaft member connected to the first output member and serving as an output member of a driving force; 3) a first cam mechanism including: i) a first cam face formed on the first output member, and ii) a second cam face formed on the shaft member, the first cam face and the second cam face being so connected with each other as to oppose each other in an axial direction, to thereby cause respectively a first axial thrust force and a second axial thrust force according to the driving torque; and 4) a frictional clutch disposed between the first output member and the second output member, and transmitting a differential limit torque, wherein the first axial thrust force caused to the first output member presses the frictional clutch from a first axial end, and the second axial thrust force caused to the shaft member presses the frictional clutch from a second axial end opposite to the first axial end.
