(54) Differential limiter


(57) A differential limiter (1), including: differential mechanism (11), including: input member (3), first output member (5), second output member (7), and differential gear (9) connecting the above three members (3,5,7) so that the above three members differentially rotate; shaft member (13) connected to the first output member (5) and serving as output member of driving force; first cam gear (23) including: first cam face (15) on the first output member (5), and second cam face (17) on the shaft member (13), the first cam face (15) and second cam face (17) are oppositely connected with each other in axial direction, to cause first axial thrust force and second axial thrust force according to driving torque; and frictional clutch (25) between two of the above three members, and transmitting a differential limit torque. The first axial thrust force (19) of the first output member (5) presses the frictional clutch (25) from first axial end. The second axial thrust force (21) of the shaft member (13) presses the frictional clutch (25) from second axial end.
