Abstract: Guide portions that guide a winding include a plurality of guide grooves which is provided at each boundary between adjacent wind surfaces, and which is extended in a winding direction of the winding. The plurality of guide grooves is arranged side by side in a radial direction of a stator at an equal pitch. The guide groove provided at an arbitrary boundary among the boundaries is offset in the radial direction relative to the guide groove provided at the adjacent boundary at the opposite side to the winding direction with reference to an orthogonal direction to the radial direction of the motor stator. Respective offset directions and offset amounts of the guide grooves are consistent.

Abstract: A wind portion of an insulator includes a side surface at the same side as, in a circumferential direction, a second guide surface which is orthogonal to a holding surface capable of holding a coil and which guides a winding in an inner-diameter direction, and an end surface orthogonal to the side surface. A first corner formed at a boundary between the holding surface and the side surface as viewed in the axial direction of a motor stator is located at a guiding-direction side by a first guide surface relative to a second corner formed at a boundary between the first guide surface and the second guide surface. The winding is extended from the second corner to the first corner.

Abstract: An insulator includes an extended portion extended along the axial direction of a motor stator from an annular member. The extended portion includes at least one protruding portion protruding in the outer-diameter direction from a guide surface that guides a winding in the circumferential direction of a motor stator. This protruding portion includes an abutting surface capable of abutting the winding guided by the guide surface. The abutting surface includes a slant portion that comes close to the annular member toward the outer-diameter direction. The slant portion is capable of abutting a semicircular portion of the winding with the circular cross-sectional shape at the outer-diameter side.
