A power interrupting apparatus is provided with: a first rotating member, a second rotating member, a clutch device adapted to interrupt a coupling between the first rotating member and the second rotating member, and an actuator adapted to actuate the clutch device. The actuator is disposed on a radially outer periphery of a part of one of the first rotating member and the second rotating member.

Power interrupting apparatus and power transmitting apparatus

A clutch device is used in combination with a differential device. The clutch device is comprised of: a clutch housed in and rotatable with the differential device and axially movable from a disengaged state into an engaged state; a plunger slidably fit on the differential device and being axially movable from a first position where the plunger does not force the clutch to a second position where the plunger forces the clutch into the engaged state; an anti-rotated solenoid configured to drive the plunger; and a retainer supported by the differential device and in contact with both the plunger at the first position and the solenoid, whereby the plunger is barred from going beyond the first position and the solenoid is axially positioned in place.

Clutch device

A differential device differentially distributes a driving force to first and second axles. The differential device is comprised of a differential gear set configured to allow differential motion between the first and second axles, a casing rotatable about an axis, the casing housing and being drivingly coupled with the differential gear set and including a first end wall, a second end wall axially opposed to the first end wall, and a side wall disposed radially outward, which in combination with the first end wall and the second end wall defines a chamber configured to house the differential gear set, a clutch engageable with the differential gear set, a solenoid configured to drive the clutch, which is disposed adjacent to the first end wall, and a magnetic core fixed to the solenoid. The magnetic core is comprised of a sleeve portion snugly and slidably fitting around an outer periphery of the side wall to radially position the core and the solenoid in place.
