A resolver fixing structure which does not cause distortion at a resolver stator is provided. The resolver fixing structure arranged between coil ends of a stator constituting a rotating electrical machine includes a ring portion as a base member having a hole, and a resolver stator press-fitted into the hole. The resolver stator has an outer circumferential portion provided with a shield member coming into contact with the hole.

A resolver external conductor fixing structure which includes a connection body having a plurality of leads, and a terminal pin holding part formed on a portion of an insulation cover for an annular stator. The terminal pin holding part and the connection body are configured to detachably engage to allow the leads to be disconnected during assembly of a resolver and connected when assembly is complete.

Plurality of air gaps are formed in a torus-shaped stator body of the resolver. If a straight line were drawn from a center point of the stator body toward the outside in the radial direction of the stator body and the straight line were rotated 360 degrees about the center point, the straight line would intersect with at least one of an inside air gap and an outside air gap. Therefore, magnetic flux (i.e., noise caused by magnetism) that has penetrated from the outer peripheral surface side of the stator body will always pass through a portion of the stator body that is to the outside in the radial direction of the air gaps, such that a large portion of the magnetic flux is eliminated by the air gaps.
