  • Publication number: 20220209608
    Abstract: In a motor, a wire terminal, to which an end at an end of winding of a wire is connected, is held by an insulator that is held by a stator core. The wire terminal comprises: a substrate connection section; plural legs held by a split insulator; a plate section, a thickness direction of which faces a radial direction, between the legs and the substrate connection section; and a wire connection section, a portion of which projected from the plate section is bent to hold the wire on an inner side. An elastic section is a meandering section meandering to turn back in a circumferential direction between the plate section and the substrate connection section, and extends from an end on another side in the circumferential direction of the plate section toward the substrate connection section.
