Abstract
A power transmission interrupting device includes: an interrupting member that is restrained from rotating relative to the first rotating member, has engaging teeth engaging with a second rotating member, and is movable in an axial direction between a coupling position at which the engaging teeth engage with the second rotating member and an uncoupling position at which the engaging teeth do not engage with the second rotating member; and a moving mechanism that moves the interrupting member in the axial direction. The moving mechanism has an annular electromagnet, a yoke, and a moving member. The moving member has a cylindrical part facing an inner circumferential surface or an outer circumferential surface of the electromagnet, and an annular cover extending from one end of the cylindrical part in a radial direction and covering one of axial end faces of the electromagnet.
