Abstract
A differential gear includes: a first output gear; a second output gear; a differential case; a clutch member configured to move in a direction of a rotation axis between a connecting position where the differential case is connected to the first output gear in a relatively non-rotatable manner and a non-connecting position where the differential case and the first side gear are allowed to rotate relative to each other; an electromagnetic coil having a cylindrical shape and configured to move the clutch member in the direction of the rotation axis; and a yoke having an annular shape and serving as a magnetic path of a magnetic flux of the electromagnetic coil. The clutch member has an outermost diameter smaller than an inside diameter of the yoke.
