Abstract: Provided is a rotor 10 capable of avoiding an increase in cost due to use of a high-performance winding machine and an increase in cost due to molding of the entire rotor 10 with an insulator, and a rotating machine including the rotor 10. The rotor 10 includes a rotor core 11 that rotates around a rotary axis A. The rotor core 11 includes a plurality of unit through holes 11a that individually accommodate each of a plurality of winding units 12. Each of the plurality of winding units 12 includes an iron core, a field winding wound around the iron core, and an insulating sealing resin that seals the iron core and the field winding, and is accommodated in the unit through hole 11a in a posture extending in a direction of the rotary axis A.

Abstract: The present invention comprises a permanent magnet (13) that is disposed around a rotor shaft (11), a retaining ring (14) that is press-fitted around the outside of the permanent magnet (13) from one end of the rotor shaft (11) so as to retain the permanent magnet (13) against the rotor shaft (11), and an end plate (12) that is provided adjacent to the permanent magnet (13) in the axial direction of the rotor shaft (11) and guides the press-fitted retaining ring (14), maintaining planar contact with the inner circumferential surface thereof, toward the permanent magnet (13) while causing the retaining ring (14) to expand as the retaining ring (14) progresses from one end of the rotor shaft (11) to the other end of the rotor shaft (11). Concentration of stress on the retaining ring (14) during press-fitting can thus be minimized.

Abstract: A grommet opening/closing apparatus includes one opening/closing device and the other opening/closing device. Both opening/closing devices are arranged oppositely against each other, each having a plurality of hooks and a driving unit to open and close the plurality of hooks. A base portion of the plurality of hooks of the one opening/closing device expands and returns one end of a grommet, and a base portion of the plurality of hooks of the other opening/closing device expands and returns the other end of the grommet. One end of the grommet is held by half-opening the hooks of the one opening/closing device, the closed hooks are inserted in the other end of the grommet. Thereafter, the hooks of both opening/closing devices are completely opened, and the wiring harness is passed through the grommet.

Abstract: In a rotor structure of a permanent magnet type rotary machine comprising a cylindrical permanent magnet 3 fixed on an outer peripheral surface of a rotor shaft 2, wherein torque acting on the permanent magnet 3 is transmitted to the rotor shaft 2, the rotor structure further comprises two annular side plates 4 and a holding ring 5. Each side plate has an axial hole 4a into which the rotor shaft 2 is fitted so as to rotate with the side plates integrally and the side plates 4 are attached on the both end surface of the permanent magnet 3, respectively so as to confront with each other. A circular U-shaped groove 4c coaxially with the axial hole 4a is provided at a end surface 4b for facing with the permanent magnet 3 of each side plate 4. The holding ring 5 is formed cylindrically and covers circumferential sections of the permanent magnet 3 and the side plates 4 and fasten the permanent magnet 3 and the side plates 4 so as to move them integrally.
