However, the engagement portion 402 may be formed in a rib shape or a protrusion shape, and the third engagement portion 414 may be formed in a groove shape. Further, in this embodiment, there are a plurality of the engaging portions 402 and the third engaging portions 414 installed, but the rotor ring 41 rotates around the center axis Z with respect to the mounting member 40 or is laterally displaced. As long as it can be prevented, only one piece may be provided correspondingly. Further, the total axial height of the first upright wall portion 43 c and the second upright wall portion 44 c is approximately the same as or slightly larger than the axial height of the outer peripheral surface 413 of the rotor ring 41.

  The mounting member 40 is provided with an annular fitting groove 403 that is recessed inwardly outside the enclosure 401. In this embodiment, the fitting groove 403 includes a first inclined surface 434, a second inclined surface 444, and the like. Thus, the cross section that opens to the outside is formed in a substantially V shape.

At least a portion of the Thereby, the rotor means 4 can be held flat on the upper surface 211 of the base 21.

When assembling the rotor means 4 and assembling the rotor means 4 to the holding unit 220, as shown in FIGS. 5, 7, 8, and 10, the third engagement portion 414 of the rotor ring 41 is while corresponding to the first engagement portion 433 of the first cover member 43, the rotor ring 41 is moved until it hits the first contact surface 431 towards the first cover member 43. Then, for example, the third engaging portion 414 formed in a rib shape is engaged with the first engaging portion 433 formed in a groove shape, for example, and the outer peripheral surface 413 of the rotor ring 41 is a first upright. It is in contact with the wall 43c.

Next, the second cover member 44 faces the first cover member 43 while the second engagement portion 443 of the second cover member 44 corresponds to the third engagement portion 414 of the rotor ring 41. Once moved to the cover, with a second abutment surface 442 of the second cover member 44 is brought into contact with the second contact surface 432 of the first cover member 43, the first to the second engaging portion 443 The third engaging portion 414 is engaged, and the second upright wall portion 44 c is brought into contact with the outer peripheral surface 414 of the rotor ring 41.

Then, the nut 451 is inserted into the corresponding first connection hole 437 and is locked to the first shoulder 438. The bolt 452 passes through the corresponding first connection hole 437 and the second connection hole 447, is locked to the second shoulder portion 448, and is screwed into the corresponding nut 451. Thus, the rotor ring 41 is sandwiched between the first cover member 43 and the second cover member 44, and the second cover member 44 and the first cover member 43 are screwed together by the connecting unit 45. . As a result, the assembly of the rotor means 4 is completed. Since the second cover member 44 and the first cover member 43 are tightly fastened to each other by screwing the bolt 452 to the nut 451, the first contact surface 441 of the second cover member 44 and the first cover member 44 a first contact surface 431 of the first cover member 43 is brought into contact with the rotor ring 41. Thus, since the rotor ring 41 can be stably held by the first cover member 43 and the second cover member 44, the rotor ring 41 can be prevented from moving up and down.

When the assembly of the rotor means 4 is finished, the holding portion of the guide wheel 25 is arranged so that the first inclined surface 253 and the second inclined surface 254 are brought into contact with the first inclined surface 434 and the second inclined surface 444, respectively. A part of 252 is inserted into the fitting groove 403 of the mounting member 40. Next, the rotating shaft 232 is fitted and inserted into the guide wheel 25 and the bearing 24, and the stopper member 26 is screwed with the threaded protruding end portion 233 of the rotating shaft 232 and is engaged with the upper portion of the guide wheel 25. Thereby, the assembly work of the rotor means 4 and the holding unit 220 is completed.
As described above, the assembly work of the rotor means 4 and the assembly work of the rotor means 4 and the holding unit 220 are performed by uneven fitting, screw tightening, etc., so that the assembly work can be performed without taking time and effort. The manufacturing cost can be greatly reduced.

  As shown in FIGS. 2 and 4, the drive means 5 includes a frame 51, a drive motor 52 attached to the frame 51, and the first gear portion 436 or the second gear portion 436 of the first cover member 43. A gear 53 is connected to the drive motor 52 so as to mesh with the second gear portion 446 of the cover member 44, and is rotatably provided in conjunction with the drive by the drive motor 52. As a result, the drive motor 52 rotates the mounting member 40 via the gear 53. In this embodiment, the gear 53 is engaged with the second gear portion 446, but may be provided so as to be engaged with the first gear portion 436. In some cases, only one of the first gear portion 436 or the second gear portion 446 may be provided.

  As shown in FIGS. 1, 2, 5, and 8, when the drive motor 52 is driven, the mounting member 40 is interlocked via the gear 53 and the stator means 3 about the central axis Z. Is rotated against. When the mounting member 40 rotates, the rotor ring 41 is rotated in conjunction with it. When the rotor ring 41 rotates, the magnet 42 attached to the rotor ring 41 is also rotated. When the mounting member 40 rotates, the guide wheel 25 is also rotated in conjunction with it. When the magnet 42 rotates, the lines of magnetic force generated by the magnet 42 cross the stator coil 32, so that electric power can be generated by the stator coil 32. The electric power generated by the stator coil 32 may be sent to a power storage device and stored, or may be sent to a load device and used.

  The first inclined surface 253 and the second inclined surface 254 of the guide wheel 25 are in contact with the first inclined surface 434 and the second inclined surface 444 of the mounting member 40, respectively. While rotating, it is possible to prevent the mounting member 40 from moving up and down or laterally deviating. Therefore, the rotor means 4 can rotate stably. Further, the guide wheel 25 can reduce the friction between the guide wheel 25 and the mounting member 40 by the holding portion 252 being inserted into the fitting groove 403 and holding the mounting member 40. it can. Therefore, the mounting member 40 can rotate smoothly and stably with respect to the guide wheel 25.

  In the generator 200 according to the present embodiment configured as described above, the stator member 31 and the rotor ring 41 are provided at a predetermined interval in the radial direction perpendicular to the central axis Z, and the stator coil 32 and the magnet 42 are provided at a predetermined interval in the radial direction perpendicular to the central axis Z, the thickness of the generator 200 along the central axis Z can be reduced. Therefore, the generator 200 as a whole can be reduced in size and thickness. Further, the installation space can be reduced by making the generator 200 smaller and thinner. Moreover, since the mounting member 40 of the rotor means 4 can be rotated by the drive motor 52 via the gear 53, it is not necessary to use a speed reducer. Therefore, the manufacturing cost is reduced. Further, since the stator means 3, the rotor means 4 and the housing 2 are easily assembled without taking time and effort, it is possible to reduce the number of assembling steps and the manufacturing cost.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to this, It cannot be overemphasized that it can change variously in the range which does not deviate from the summary.
