Power supply side equipment comprises a high-frequency power supply, a matching box, a primary side resonance coil, an output impedance variable unit, a matching state detection unit, and a control unit. By a magnetic field resonance, the primary side resonance coil transmits power in a non-contact manner to a load through a secondary side resonance coil. At least the matching box, the primary side resonance coil, the secondary side resonance coil, and the load constitute a resonance system having a resonant frequency. The matching state detection unit detects the matching state between the input impedance of the resonance system and the output impedance of the high-frequency power supply at the resonant frequency. The control unit adjusts the output impedance variable unit and the matching box according to the detection result by the matching state detection unit so that the input impedance of the resonance system and the output impedance of the high-frequency power supply match each other.

An external cylindrical ring for use in this rotating electric machine includes a body portion and a flange, the body portion including a fastening region making internal contact with an outer circumferential surface of a stator core to be fastened to the outer circumferential surface of the stator core, and a skirt region located at a bottom surface side of a casing and having an inner diameter larger than an inner diameter of the fastening region. When the external cylindrical ring is fastened to the stator core, the deformation of the skirt region of the external cylindrical ring can be suppressed, thus enabling the dimensional accuracy of an outer surface of a cylindrical skirt region of the external cylindrical ring to fall within tolerance.
