Abstract
A power transmission interrupting device includes: an interrupting member restrained from rotating relative to a first rotating member and movable in an axial direction between a coupling position at which the interrupting member engages with the second rotating member and an uncoupling position; and a moving mechanism moving the interrupting member in the axial direction. The moving mechanism has a magnetic flux generation unit, a holder unit, and a moving member. The holder unit includes: a yoke having a cylindrical part that faces the magnetic flux generation unit in a radial direction; and a restraint member having an axial movement restraining part that is fixed to the yoke and restrains the magnetic flux generation unit from moving in the axial direction relative to the cylindrical part, and a rotation restraining part that is locked in a locking portion provided in the case member and restrains the yoke from rotating.
