摘要： There is provided in a die a cavity for placing a powder magnetic core material, and a recessed curved surface bent inward of the die is formed at the bottom surface of the cavity. The powder magnetic core material placed in the cavity is pressed by the pressing surface of a punch to the side and bottom surfaces of the cavity to form a split tooth body. As a result, a projected curved surface having a shape following the recessed curved surface is formed on the outer peripheral surface of the split tooth body. Then, two split tooth bodies are butted and joined together at the surfaces to which pressing force by the punch is applied, and thereby a tooth is assembled.

摘要： A core (10) comprises a plurality of core split members (11) having yoke portions (22) and tooth portions (21) and arranged in such a circumferential shape that the yoke portions (22) contact with each other while the tooth portions (21) being directed inward. The core (10) further comprises a ring (12) contacting with the yoke portions (22), and stoppers (13) mounted on the outer face sides of the yoke portions (22) for fixing the ring (12) on the yoke portions (22). The yoke portions (22) and the ring (12) are formed in corrugated shape to mesh with each other, and the stoppers (13) are formed with projections that engage with the inner side of the ring (12). This structure provides both the rotating electrical machine core having the core split members arranged in the circumferential shape and fastened to each other while preventing occurrence of a stress and a positional displacement between the core split members, and a rotating electrical machine.

摘要： A battery (1) is arranged outside a compartment. A service plug (160) is arranged in the compartment. The service plug (160) is a shutoff device that can shut off an output path of the battery (1) by a manual operation. When a vehicle (500) is hard hit at the front and a circuit of PCU (200) is damaged, an excessive current may flow to the PCU (200), possibly generating heat or smoke from the PCU (200). When the vehicle (500) goes wrong, a person on board the vehicle may pull out the service plug (160), whereby the power supply path from battery (1) to PCU (200) can be shut off.

摘要翻译： 电池（1）布置在隔室外。 服务插头（160）布置在隔室中。 服务插头（160）是可以通过手动操作来切断电池（1）的输出路径的切断装置。 当车辆（500）在前方受到严重撞击并且PCU（200）的电路损坏时，过多的电流可能流向PCU（200），从PCU（200）可能产生热量或烟雾。 当车辆（500）出错时，车上的人员可以拉出服务插头（160），从而可以切断从电池（1）到PCU（200）的电源路径。

摘要： A rotor (120) that can reduce the used amount of resin for securing a permanent magnet (123) is provided. The rotor (120) includes a rotor core (125) provided fixedly to a rotation shaft (110) and having a magnet insertion hole (126) extending in an axial direction formed therein, a permanent magnet (123) embedded in the magnet insertion hole (126) and extending in the axial direction and extending in a direction inclined relative to a radial direction of the rotor core (125), and a resin layer (137) that secures the permanent magnet (123) to the rotor core (125). The resin layer (137) covers a surface of the permanent magnet (123) and is in contact with an inner surface of the magnet insertion hole (126). A hollow space (132) extending in the axial direction is left in the magnet insertion hole (126) at an inner side in the radial direction relative to the permanent magnet (123). Part of the inner surface of the magnet insertion hole (126) is exposed to the hollow space (132).
