A resolver body including a rotor having Nx (Nx is a natural number) salient poles, a stator facing the rotor and having Ns (Ns is an integer equal to or larger than 3) teeth arranged in a circumferential direction, and an excitation winding and two phases of output windings wound on each tooth; and an excitation circuit configured to apply voltage to the excitation winding. The excitation winding and the two phases of output windings wound on each of Nsm (Nsm is an integer equal to or larger than 2) teeth among the Ns teeth are set to be of a main system. The excitation winding and the two phases of output windings wound on each of Ns-Nsm teeth are set to be of a sub-system. The number Nsm of the teeth corresponding to the main system is larger than the number Ns-Nsm of the teeth corresponding to the sub-system.

According to one embodiment, each of the first piece portions of a fixing ring is elastically deformed with a first bent portion to be bent toward a first surface side serving as a point of origin. In a map shape formed by projecting a plurality of broad portions and the first piece portions onto a virtual plane parallel to the first surface, each of the first bent portion intersects a straight line passing through a contact point of a circumscribed circle in contact with an outer circumferential edge of the broad portion on which the first piece portion is provided and a center point of the circumscribed circle. Each of the first piece portions is positioned between an inscribed circle in contact with an inner circumferential edge of the first piece portion and the first bent portion.
