摘要： A thermistor includes a case having a bottom section at one end and an opening section at the other end, a thermistor element housed in the case, a conducting wire housed in the case and connected to the thermistor element, and a lead wire connected to the conducting wire. The lead wire has a first portion including an insulating coating, and a second portion connected to the conducting wire and exposed from the insulating coating. A resin is filled up to a position away from an end edge of the opening section toward the bottom section so as to enclose at least the thermistor element, the conducting wire, and the second portion. The first portion is guided out of the resin to the outside of the case. An inner peripheral surface of the opening section is curved so as to increase an opening area of the opening section.

摘要： A stator includes a stator core, a plurality of phase windings, a neutral line and a fixing portion. The plurality of phase windings is wounded a plurality of times by a predetermined winding method crossing between a plurality of slots. One lead end of each phase winding is a neutral point connecting portion, and the one lead end is pulled out from an axially end portion of the stator core. The neutral line connects the neutral point connecting portions of the phase windings of different phases together. The neutral line is separate from the phase windings. The fixing portion fixes a first phase winding that is connected to the neutral line. A second phase winding is adjacent to the first phase winding together.

摘要： A rotor 14 includes a shaft having a coolant flow passage and a coolant supply port, a rotor core 24 fixed on the shaft and formed of laminated steel plates, and a magnet set 32 provided in the rotor core 24 to extend along an axial direction thereof. The rotor core 24 has a first flow passage 34 provided near the magnet to extend therealong and a second flow passage 36 that connects the coolant supply port 28 of the shaft 22 and the first flow passage 34, thereby constituting a coolant flow path. The second flow passage 36 is formed by overlapping second slits 37 formed in the respective steel plates at an axially intermediate region A of the rotor core 24, the formed position of the second slit 37 being different for each steel plate combined. The first flow passage 34 and the second flow passage 36 join at the axially intermediate region A of the rotor core 24.

摘要： A rotary electric machine rotor includes a rotor core, a rotor shaft, and a nut portion. The rotor core is made up of stacked thin magnetic plates. The rotor shaft has, on one end side, a receiving portion that abuts against one end surface in an axial direction of the rotor core, and has, on the other end side, an outer diameter threaded structure. The nut portion meshes with the outer diameter threaded structure of the rotor shaft. A position, on the rotor shaft, of a contact surface between the nut portion and the rotor core is positioned farther to the other end side in the axial direction than the outer diameter threaded structure, when the rotor core is fixed to the rotor shaft by the nut portion being fastened to the outer diameter threaded structure of the rotor shaft.
