Abstract
Differential apparatus which includes input and output members rotatable relative to each other, a clutch mechanism for interconnecting them, an actuator and a cam mechanism. The clutch mechanism includes first and second clutch members rotating with the input and output members, respectively. The actuator limits rotation of the second clutch member relative to the input member to angularly displace the second clutch member relative to the output member. The cam mechanism is provided between the second clutch member and the output member, and includes first and second cam faces rotating with the second clutch member and the output member, respectively. When the actuator operates, these cam faces cooperate to axially displace the second clutch member away from the output member, whereby the second clutch member is axially displaced to engage with the first clutch member.
