    Abstract: A bobbin for electrically insulating the stator core from a coil wire to be wound around the bobbin includes: a coil winding portion around which the coil wire is to be wound; and a terminal fixing portion to which a winding starting end portion and a winding finishing end portion of the coil wire are to be fixed. The terminal fixing portion includes a first groove configured to guide a winding starting section extending from the winding starting end portion of the coil wire to a winding starting position of the coil winding portion and a second groove configured to guide a winding finishing section extending from a winding finishing position of the coil winding portion to the winding finishing end portion of the coil wire to intersect the winding starting section when seen in an axial direction.

    Abstract: A bobbin is adapted to be mounted to a projection of a stator core of a rotary electric machine and wound with a coil wire. The bobbin includes a back stress generating portion configured to generate a stress acting in a direction opposite to a stress generated when the coil wire is wound around the bobbin.

    Abstract: A rotating electrical machine comprises a stator and a rotor. The rotor includes a rotor iron core in which a permanent magnet is disposed. The rotor iron core comprises a connection part, a plurality of magnetic pole part, a first gap, and a second gap for injection of the adhesive. The connection part is configured to surround a rotational axis. The plurality of magnetic pole parts are provided in an outer portion than the connection part in a radial direction. The first gap is configured to penetrate along an axial direction between the magnetic pole parts in an outer portion than the connection part in the radial direction and in which the permanent magnet is fixed with adhesive. At least one of the second gaps is provided for each of the first gaps in communication with the first gap.
