The power generation device 42 is configured to include the power generation unit 40. The wheel hub assembly 20 also includes, for example, an electrical component 58. The wheel hub assembly 20 includes a cable 88. For example, the wheel hub assembly 20 also includes an auxiliary component 92. The wheel hub assembly 20 includes, for example, at least one connector 70.

[0081] <Hub Axle 22>

[0082] like Figure 4As shown, the hub axle 22 rotatably supports the hub housing 24 and has a central axis C1. The axial direction X1 about the central axis C1 includes a first axial direction A1. The axial direction X1 includes, for example, a second axial direction A2 opposite to the first axial direction A1. The hub axle 22 is mounted, for example, to the frame end of the frame 14 of the human-powered vehicle 10. The hub axle 22 is also mounted, for example, to the rear end of the frame 14 of the human-powered vehicle 10. The hub axle 22 includes, for example, a hollow portion having a peripheral wall portion 22A. In this embodiment, the peripheral wall portion 22A is provided on the end cap 28.

[0083] The hub axle 22 includes, for example, a shaft member 26 and at least one end cap 28. The hub axle 22 may also include, for example, an additional end cap 30. The hub axle 22 includes a positioning member 80. The hub axle 22 includes a first frame abutting end face 22B, a second frame abutting end face 22C, and at least one cable guide 90.

[0084] Shaft member 26 has a central axis C1. The central axis of shaft member 26 coincides with the central axis C1 of hub shaft 22. Shaft member 26 rotatably supports hub housing 24. Shaft member 26 is, for example, a hollow shaft and includes an inner surface 26A and an outer surface 26B in a radial direction X2 about the central axis C1. Shaft member 26 includes end portions 26C. End portions 26C include one end portion 26C and another end portion 26C in an axial direction X1.

[0085] At end 26C, an end cap 28 is mounted axially X1 about the central axis C1 of the shaft member 26. At least one end cap 28 is mounted axially X1 to end 26C of the shaft member 26. The at least one end cap 28 includes, for example, end cap 28X and an additional end cap 30. The end cap 28 is mounted to end 26C. For example, end cap 28X is mounted to one end 26C axially X1, and additional end cap 30 is mounted to the other end 26C axially X1. External threads are provided at end 26C of the shaft member 26, for example. The end cap 28 forms, for example, a hollow portion having a peripheral wall portion 22A of the hub shaft 22.

[0086] like Figure 4 and Figure 7As shown, the end cap 28X is positioned on the first axial side A1 relative to the shaft member 26. The end cap 28X is embedded in the end portion 26C of the shaft member 26. The positioning member 80 is configured to determine the position of the end cap 28X relative to the shaft member 26 in the circumferential direction X3 about the central axis C1. For example, the positioning member 80 extends in the radial direction X2 about the central axis C1. The positioning member 80 is, for example, separately constructed from the end cap 28X and the shaft member 26. The positioning member 80 includes, for example, a pin member. The end cap 28X has a first positioning portion 28A. The end portion 26C of the shaft member 26 has a second positioning portion 26D. The positioning member 80 has a first portion 80A and a second portion 80B that is different from the first portion 80A. The first positioning portion 28A positions the first portion 80A. The second positioning portion 26D positions the second portion 80B.

[0087] For example, one of the first configuration portion 28A and the second configuration portion 26D includes a positioning hole 82A. The first configuration portion 28A of the end cap 28X includes, for example, a positioning hole 82A. For example, the positioning hole 82A holds the positioning member 80. A first portion 80A of the positioning member 80 is pressed into the positioning hole 82A, thereby holding the positioning member 80 in the positioning hole 82A.

[0088] For example, the other of the first configuration portion 28A and the second configuration portion 26D includes a positioning recess 82B. The second configuration portion 26D of the end portion 26C of the shaft member 26 includes, for example, the positioning recess 82B. For example, the positioning recess 82B receives the positioning member 80. The second portion 80B of the positioning member 80 is disposed in the positioning recess 82B, so that the positioning recess 82B receives the positioning member 80.

[0089] For example, the positioning recess 82B is open at least radially X2 about the central axis C1. With the second portion 80B of the positioning member 80 disposed in the positioning recess 82B, the opening of the positioning recess 82B has a gap between the positioning member 80 and one of the sides of the positioning recess 82B in the circumferential X3. With the second portion 80B of the positioning member 80 disposed in the positioning recess 82B, the opening of the positioning recess 82B is formed at the end 26C of the shaft member 26 in such a way that the positioning member 80 and one of the sides of the positioning recess 82B in the circumferential X3 do not contact each other. The opening of the positioning recess 82B can also be formed such that the second portion 80B of the positioning member 80 is pressed into the positioning recess 82B in a removable manner. The positioning recess 82B is, for example, continuous radially X2 from the outer surface 26B to the inner surface 26A. If the positioning recess 82B opens at least on the outer surface 26B in a manner that receives the positioning member 80, it may also not be continuous from the outer surface 26B to the inner surface 26A in the radial direction X2. The positioning member 80 includes, for example, an additional positioning member 80X. The additional positioning member 80X is configured to determine the position of the end cap 28 relative to the shaft member 26 in the axial direction X1. In this embodiment, the additional positioning member 80X is configured to determine the position of the end cap 28X relative to the shaft member 26 in the axial direction X1. The additional positioning member 80X includes, for example, an O-ring. The additional positioning member 80X includes, for example, a resin material.

[0090] The additional end cap 30, for example, has an internal thread that engages with the external thread of the end cap 26C. The additional end cap 30 is mounted to the shaft member 26 to determine the position of the additional bearing 30A relative to the shaft member 26 in the axial direction X1. The additional bearing 30A can also be mounted to the shaft member 26 by a nut.

[0091] like Figure 1 As shown, the first frame abutment end face 22B is, for example, one end face on the axial direction X1 of the shaft member 26, and the second frame abutment end face 22C is, for example, another end face on the axial direction X1 of the shaft member 26. The second frame abutment end face 22C is the end face opposite to the first frame abutment end face 22B on the axial direction X1 about the central axis C1. In this embodiment, the first frame abutment end face 22B and the second frame abutment end face 22C are respectively provided on the end face of the end cover 28. The first frame abutment end face 22B is provided on the end face of the end cover 28X, and the second frame abutment end face 22C is provided on the end face of the additional end cover 30.

[0092] Frame 14 includes a first frame 14A and a second frame 14B. The first frame abutment face 22B is, for example, opposite to the first frame 14A. The second frame abutment face 22C is, for example, opposite to the second frame 14B. The first frame abutment face 22B and the second frame abutment face 22C abut against the frame 14 of the manually driven vehicle 10 when the shaft member 26 is mounted to the frame 14. The distance along the axial direction X1 from the first frame abutment face 22B to the second frame abutment face 22C defines the overlock nut dimension of the hub assembly 20.

[0093] <Hub housing 24>

[0094] The hub housing 24 is configured to rotate about a central axis C1. The hub housing 24 rotates relative to the shaft member 26. The hub housing 24 surrounds the outer surface 26B of the shaft member 26. The hub assembly 20 also includes, for example, an additional bearing 30A. The additional bearing 30A is provided axially X1 at the end of the hub housing 24 on the side of the additional end cap 30. The additional bearing 30A supports the hub housing 24 in a manner that allows it to rotate relative to the shaft member 26. The internal space H1 of the hub housing 24 houses a portion of the shaft member 26, the generator 40, the housing 62, the housing restraint member 62X, and a portion of the cable 88.

[0095] <Sprocket Support 32>

[0096] like Figure 1 and Figure 2 As shown, the sprocket support 32 is mounted to the hub housing 24 via the torque transmission structure 36. The sprocket support 32 is mounted to one end of the hub shaft 22 along the axial direction X1. The sprocket support 32 is configured to rotatably about a central axis C1 and mounts at least one sprocket 12. The sprocket support 32 rotates relative to the shaft member 26, for example, and mounts at least one sprocket 12. The sprocket support 32 has a sprocket engagement portion 32A that engages with the sprocket 12. The sprocket engagement portion 32A includes, for example, a spline.

[0097] like Figure 7As shown, a bearing 34 is provided, for example, on a shaft member 26, supporting the sprocket support 32 in a manner that allows the sprocket support 32 to rotate relative to the shaft member 26. The bearing 34 is provided on the sprocket support 32, for example, via a support member 34D. The bearing 34 is connected to the sprocket support 32 via a bearing 35. The bearing 34 may include multiple bearings 34, or it may be a single bearing 34. The bearing 34 may include, for example, an outer ring 34A, an inner ring 34B, and a rotating body 34C. The outer ring 34A is provided radially inside the sprocket support 32 via a second one-way clutch portion 38B. The inner ring 34B is provided on the outer surface of the shaft member 26. The rotating body 34C is provided between the outer ring 34A and the inner ring 34B in a manner that allows the outer ring 34A to rotate relative to the inner ring 34B. For example, the rotating body 34C is a ball, and the bearing 34 is a ball bearing. The bearing 34 may also be a roller bearing.

[0098] <Torque Transmission Structure 36>

[0099] The torque transmission structure 36 transmits torque from one of the sprocket support 32 and the hub housing 24 to the other. For example, at least a portion of the torque transmission structure 36 is provided in a non-removable manner to the sprocket support 32. For example, the torque transmission structure 36 includes a one-way clutch 38. The one-way clutch 38 is included in the torque transmission structure 36 that transmits torque from the sprocket support 32 to the hub housing 24.

[0100] The one-way clutch 38 includes at least one of, for example, a roller clutch, a splash clutch, and a ratchet clutch. The one-way clutch 38 transmits torque from the sprocket support 32 to the hub housing 24 when the speed at which the sprocket support 32 rotates in a predetermined direction is greater than the speed at which the hub housing 24 rotates in a predetermined direction corresponding to the direction of travel of the manually driven vehicle 10. When torque is transmitted from the sprocket support 32 to the hub housing 24, the sprocket support 32 and the hub housing 24 rotate integrally. The transmission of torque from the sprocket support 32 to the hub housing 24 occurs, for example, when the manually driven vehicle 10 is driven by rotating the crank of the manually driven vehicle 10. The one-way clutch 38 is configured to allow relative rotation between the hub housing 24 and the sprocket support 32 when the speed at which the hub housing 24 rotates in a predetermined direction is greater than the speed at which the sprocket support 32 rotates in the predetermined direction. The relative rotation of the one-way clutch 38 is allowed, for example, when the manually driven vehicle 10 is coasting.

[0101] The one-way clutch 38 includes a first one-way clutch portion 38A and a second one-way clutch portion 38B. The first one-way clutch portion 38A includes, for example, an outer ring of the one-way clutch 38.

[0102] The first one-way clutch portion 38A rotates integrally with the sprocket support 32. The first one-way clutch portion 38A is formed integrally with the sprocket support 32, for example. The first one-way clutch portion 38A may also be formed separately from the sprocket support 32. The first one-way clutch portion 38A is provided, for example, on the inner surface of the sprocket support 32. For example, the first one-way clutch portion 38A is positioned further outward than at least a portion of the second one-way clutch portion 38B in a radial direction X2 about the central axis C1.

The sprocket support 32 and the torque transmission structure 36 are mounted to the hub housing 24 in a manner that allows them to be detached and assembled via the connecting portion 36A. The connecting portion 36A connects the second one-way clutch portion 38B to the hub housing 24 in a manner that allows it to rotate integrally with the hub housing 24. For example, the connecting portion 36A is formed separately from the hub housing 24 and is mounted to the hub housing 24 in a manner that prevents it from rotating relative to the hub housing 24. For example, the connecting portion 36A is formed separately from the second one-way clutch portion 38B and is mounted to the second one-way clutch portion 38B in a manner that prevents it from rotating relative to the second one-way clutch portion 38B.

The tool engaging portion 36C is located radially outward of the sprocket support 32 about the central axis C1 in a radial direction X2. For example, the tool engaging portion 36C is provided on the outer surface 36D formed radially outward of the protrusion 36B about the central axis C1. The outer surface 36D formed radially outward of the protrusion 36B about the central axis C1 is located radially outward of the inner surface of the hub housing 24 in a radial direction X2. The inner surface of the hub housing 24 is located at the end of the hub housing 24 where the connecting portion 36A is mounted. The outer surface 36D formed radially outward of the protrusion 36B about the central axis C1 is located radially X2 further outward than at least a portion of the outer surface of the hub housing 24. The outer surface of the hub housing 24 is located at the end of the hub housing 24 where the mounting connection 36A is installed. The tool engaging portion 36C is located axially X1 about the central axis C1 on the side closer to the hub housing 24 than the sprocket engaging portion 32A. The tool engaging portion 36C is provided on the outer surface 36D, for example, in a manner that it is integrally located on the side closer to the hub housing 24 than the sprocket engaging portion 32A.

[0109] For example, tool T1 is used to mount torque transmission structure 36 to hub housing 24 with hub housing 24 disposed on shaft member 26.

[0115] <46 spools>

[0116] like Figure 9 and Figure 10 As shown, the spool 46 is disposed on the shaft member 26 in a manner that does not rotate relative to the shaft member 26. Therefore, when the shaft member 26 does not rotate, the spool 46 does not rotate. On the other hand, when the shaft member 26 rotates, the spool 46 rotates integrally with the shaft member 26. In this embodiment, the shaft member 26 does not rotate. The central axis of the spool 46 coincides with the central axis C1 of the hub shaft 22. The spool 46 includes a winding arrangement portion 46A and a first flange 46B. The spool 46 includes, for example, a second flange 46C. A winding 50A is wound on the spool 46. The winding 50A is wound on the winding arrangement portion 46A of the spool 46. For example, the winding 50A is disposed in the winding arrangement portion 46A. The second flange 46C is configured to protrude radially X2 from the end of the winding arrangement portion 46A opposite to the first flange 46B in the axial direction X1. The first axial direction A1 is from the winding arrangement portion 46A toward the first flange 46B. For example, the first axial direction A1 is from the winding 50A toward the first spool end 46X. The second axial direction A2 is from the winding arrangement portion 46A toward the second spool end 46Y. The second spool end 46Y is the end opposite to the first spool end 46X in the axial direction X1.

[0117] like Figure 9 and Figure 10As shown, for example, a first flange 46B extends radially outward from the end of the winding configuration portion 46A in the axial direction X1 toward the central axis C1 of the spool 46. The first flange 46B is configured to project radially X2 beyond the winding configuration portion 46A from the end of the winding configuration portion 46A. For example, the first flange 46B includes a plurality of protrusions 48 projecting toward the first axial direction A1. The protrusions 48 project from the first flange 46B toward the first axial direction A1. For example, the plurality of protrusions 48 includes a first protrusion 48A and a second protrusion 48B. The first protrusion 48A projects from the first flange 46B toward the first axial direction A1 in a manner that does not contact the limiting member 52 in the first axial direction A1. For example, the amount of projection of the second protrusion 48B toward the first axial direction A1 is greater than that of the first protrusion 48A. The second protrusion 48B projects toward the first axial direction A1 in a manner that extends beyond the limiting member 52 in the first axial direction A1. The plurality of protrusions 48 includes, for example, a plurality of first protrusions 48A and a plurality of second protrusions 48B. In this embodiment, the plurality of protrusions 48 includes 14 first protrusions 48A and 2 second protrusions 48B. The 2 second protrusions 48B are arranged adjacent to each other in the circumferential direction X3.

[0118] like Figure 8 and Figure 9 As shown, the yoke 42D is disposed on the spindle 46. A portion of the yoke 42D is disposed radially inward (X2) from the spindle 46. Another portion of the yoke 42D is disposed radially outward (X2) from the spindle 46. The power generation device 42 includes a plurality of yokes 42D. The plurality of yokes 42D are arranged circumferentially (X3). A portion of the plurality of yokes 42D is supported by a first flange 46B, and another portion of the yokes 42D is supported by a second flange 46C. A portion of the yoke 42D supported by the first flange 46B is disposed between two adjacent protrusions 48.

[0119] A magnetic yoke 42D is positioned opposite a magnet 44 in the radial direction X2. The magnetic yoke 42D includes a first magnetic yoke 42X and a second magnetic yoke 42Y. The first magnetic yoke 42X is arranged adjacent to the second magnetic yoke 42Y in the axial direction X1. The first magnetic yoke 42X is positioned on a first flange 46B between two adjacent protrusions 48 in the circumferential direction X3. The second magnetic yoke 42Y is positioned on a second flange 46C between two adjacent third protrusions 48C in the circumferential direction X3. The third protrusions 48C protrude from the second flange 46C toward a second axial direction A2. The first magnetic yoke 42X and the second magnetic yoke 42Y are each composed of a plurality of magnetic yoke plates.

[0120] <Leader 50B>

[0121] Lead 50B is electrically connected to winding 50A. Lead 50B delivers the current generated in winding 50A to the outside of generator section 40. Lead 50B includes, for example, a positive lead 50B and a negative lead 50B. The positive lead 50B and the negative lead 50B are respectively connected to the two ends of winding 50A. In this embodiment, lead 50B is separate from winding 50A. If lead 50B is electrically connected to winding 50A, then lead 50B can be integrated with winding 50A. Figure 14 As shown, the positive lead 50B and the negative lead 50B, which are led out to the first axial side A1, are electrically connected to the electrical component 58.

[0122] <Restriction Component 52>

[0123] The power generation device 42 includes, for example, a limiting member 52. For example, a spool 46 and the limiting member 52 are mounted on a shaft member 26. The limiting member 52 is adjacent to a first spool end 46X of the spool 46 in an axial direction X1 about the central axis C1 of the spool 46, limiting the axial movement X1 of the spool 46. The limiting member 52 restricts the movement of the spool 46 towards the first axial direction A1. For example, the limiting member 52 is welded to the shaft member 26. The limiting member 52 is mounted to the shaft member 26 by welding. For example, the limiting member 52 has a first surface 52A opposite to the first spool end 46X in the axial direction X1 and a second surface 52B opposite to the first surface 52A in the axial direction X1. When viewed from a direction perpendicular to the axial direction X1, a lead wire 50B is arranged on the limiting member 52 from the first surface 52A to the second surface 52B.

[0124] like Figure 8 As shown, the limiting member 52 includes, for example, a first limiting member 52C, a second limiting member 52D, and an additional limiting member 52X. The first limiting member 52C is adjacent to the first spool end 46X of the spool 46 in the axial direction X1 about the central axis C1 of the spool 46, limiting the movement of the spool 46 in the first axial direction A1. The first limiting member 52C is welded to the shaft member 26. The second limiting member 52D and the additional limiting member 52X are adjacent to the second spool end 46Y of the spool 46 in the axial direction X1, limiting the movement of the spool 46 in the second axial direction A2. The additional limiting member 52X includes, for example, a C-ring. By configuring the second limiting member 52D and the additional limiting member 52X on the shaft member 26, the power generation unit 40 is disposed on the shaft member 26, and the first limiting member 52C is welded to the shaft member 26, thereby configuring the power generation unit 40 on the shaft member 26. In the axial direction X1, the second limiting member 52D is disposed between the second spool end 46Y and the additional limiting member 52X.

[0125] <Lead-out guide section 54>

[0126] The lead guide portion 54 inhibits contact between the lead 50B and the limiting member 52. The lead guide portion 54 is configured, for example, to prevent contact between the lead 50B and the limiting member 52. The lead guide portion 54 is, for example, integrally provided with the spool 46. For example, at least one lead guide portion 54 comprises a resin material. For example, the entire spool 46 is formed of a resin material. The lead guide portion 54 comprises, for example, a thermosetting resin such as polyester resin or epoxy resin. For example, the lead guide portion 54 is formed of a resin material.

[0127] For example, at least one lead wire guide 54 is provided on the first flange 46B. For example, at least one lead wire guide 54 is provided on at least one of a plurality of protrusions 48. At least one lead wire guide 54 is provided on the second protrusion 48B. At least one lead wire guide 54 is provided in the recess of the second protrusion 48B that is recessed radially X2. The through portion 54A of the lead wire guide 54 is included in the recess of the second protrusion 48B that is recessed radially X2. The through portion 54A of the lead wire guide 54 is included in the hole of the second protrusion 48B that extends axially X1.

[0128] The lead wire guide portion 54 is configured to lead the lead wire 50B further toward the first axial direction A1 than the limiting member 52. At least one lead wire guide portion 54 is configured to handle at least a portion of the lead wire 50B and extend axially X1. At least one lead wire guide portion 54 has a second protrusion 48B passing through it axially X1, and the lead wire 50B has the second protrusion 48B of the at least one lead wire guide portion 54 positioned in the portion passing through axially X1. For example, the at least one lead wire guide portion 54 may include a through portion 54A that handles the lead wire 50B and passes through axially X1. The through portion 54A passes through the second protrusion 48B axially X1. For example, the at least one lead wire guide portion 54 is configured to extend beyond the first surface 52A in the first axial direction A1. The lead wire guide portion 54 is configured to extend beyond the second surface 52B in the first axial direction A1. The lead wire guide 54 may also be configured to extend beyond the second surface 52B in the first axial direction A1.

[0129] For example, at least one lead guide 54 includes a plurality of lead guides 54. One lead 50B is disposed in one lead guide 54. The number of at least one lead guide 54 is, for example, the same as the number of leads 50B. In this embodiment, at least one lead guide 54 includes two lead guides 54. The two lead guides 54 are respectively provided in different second protrusions 48B, and are respectively provided with a positive lead 50B and a negative lead 50B. The two second protrusions 48B provided with the lead guides 54 are adjacent in the circumferential direction X3 in such a manner that there are no other protrusions 48 between the two second protrusions 48B.

[0130] <Lead-out guide configuration section 56>

[0131] like Figure 9 and Figure 11 As shown, a lead wire guide configuration portion 56 is provided on the limiting member 52. At least a portion of at least one lead wire guide portion 54 is disposed in the lead wire guide configuration portion 56. For example, the lead wire guide configuration portion 56 includes at least one of a hole extending axially X1 and a recess 56B recessed radially X2 about the central axis C1 of the spool 46. In this embodiment, the lead wire guide configuration portion 56 includes a recess 56B recessed radially X2. The lead wire guide portion 54 is disposed in the recess 56B. The lead wire guide configuration portion 56 may also include a hole 56A extending axially X1. When the lead wire guide configuration portion 56 includes a hole 56A extending axially X1, the lead wire guide portion 54 may be disposed in the hole 56A. The shape of the lead wire guide configuration portion 56 can be determined according to the shape of the lead wire guide portion 54.

[0132] <Electrical Components 58>

[0133] like Figure 8 As shown, electrical component 58 is disposed inside the hub assembly 20. For example, electrical component 58 is disposed within the internal space H1 of the hub housing 24. For example, electrical component 58 is disposed at a different position from magnet 44 in the axial direction X1 about the central axis C1. Electrical component 58 is disposed in the axial direction X1 so as not to overlap with magnet 44. For example, electrical component 58 includes a battery 64X. For example, electrical component 58 includes at least one battery 64X. For example, battery 64X is electrically charged by winding 50A.

[0134] For example, electrical component 58 includes a magnetic sensor 76. Electrical component 58 includes an electrical substrate 58A. Electrical substrate 58A extends axially X1 about a central axis C1. Electrical substrate 58A is configured axially X1 at a different position from magnet 44. Electrical substrate 58A is configured axially X1 so as not to overlap with magnet 44. Electrical substrate 58A is mounted to shaft member 26. Electrical substrate 58A includes an additional electrical substrate 58Y extending radially X2. When viewed from axial X1, sensor 58X is configured on the additional electrical substrate 58Y such that at least a portion overlaps with magnet 44. Sensor 58X may, for example, include a portion of magnetic sensor 76. Sensor 58X may, for example, include at least one sensor for detecting acceleration and tilt. Sensor 58X may also include a gyroscope sensor.

[0135] <Magnetic shielding component 60>

[0136] A magnetic shielding member 60 is disposed inside the second member 42B to alter the direction of travel of the magnetic field lines of the magnet 44. The magnetic shielding member 60 alters the direction of travel of the magnetic field lines generated at least from the end of the magnet 44 along a first axial direction A1. The magnetic shielding member 60, when viewed from the axial direction X1, at least partially overlaps with the magnet 44, is located between the magnet 44 and the electrical component 58 along the axial direction X1, and extends radially X2 about the central axis C1. The magnetic shielding member 60 overlaps with the entire magnet 44 when viewed from the axial direction X1. Therefore, the magnetic shielding member 60 includes a region that overlaps with the entire magnet 44 when viewed from the axial direction X1. The magnetic shielding member 60 is disposed in the same position along the axial direction X1 as the limiting member 52. For example, the magnetic shielding member 60 comprises a soft magnetic material.

[0137] For example, the magnetic shielding member 60 extends radially X2 from the inner surface of the second member 42B inwards. For example, the first radial distance Y1 is smaller than the second radial distance Y2. For example, the first radial distance Y1 is the distance from the central axis C1 to the magnetic shielding member 60 in the radial X2 direction. The first radial distance Y1 is, for example, the distance from the central axis C1 to the end of the innermost magnetic shielding member 60 in the radial X2 direction. For example, the second radial distance Y2 is the distance from the central axis C1 to the magnet 44 in the radial X2 direction. The second radial distance Y2 is, for example, the distance from the central axis C1 to the end of the innermost magnet 44 in the radial X2 direction.

[0138] For example, the magnetic shielding member 60 is magnetically connected to the back yoke 42C. For example, the magnetic shielding member 60 is configured to contact the back yoke 42C. For example, the magnetic shielding member 60 is integrally formed with the back yoke 42C. For example, the magnetic shielding member 60 is arranged circumferentially X3 about the central axis C1. The magnetic shielding member 60 is configured such that the first radial distance Y1 is substantially the same circumferentially. For example, even when the magnet 44 is configured to rotate relative to the magnetic shielding member 60 about the central axis C1, the magnetic shielding member 60 is still arranged circumferentially, thus enabling the magnetic shielding member 60 to change the direction of travel of the magnetic field lines of the magnet 44. The magnetic shielding member 60 is formed, for example, by bending the end of the back yoke 42C radially inward. For example, the magnetic shielding member 60 is configured to contact the magnet 44. The magnetic shielding member 60 is configured to contact at least the end of the magnet 44 along the first axial direction A1.

[0139] <Outer shell 62 and outer shell limiting member 62X>

[0140] like Figure 8As shown, the hub assembly 20 further includes, for example, a housing 62 that houses at least a portion of the electrical component 58, and a housing limiting member 62X that limits the movement of the housing 62 relative to the shaft member 26. At least a portion of the electrical component 58 is disposed in the housing 62. The housing 62 is separately disposed from the hub housing 24 inside the hub housing 24. The housing 62 is, for example, made of resin material. The housing 62 houses at least a portion of the electrical component 58. For example, at least a portion of the electrical component 58 is housed in the internal space H2 of the housing 62. For example, the housing 62 includes an inner wall 62A, an outer wall 62B, an end wall 62C, and a cover portion 62D. For example, the housing 62 has a housing portion 64 for accommodating the electrical component 58. The housing 62 includes a shaft member receiving portion 66 and an opening portion 68. The housing 62 has a U-shape when viewed from the axial direction X1, for example. For example, the opening portion 68 corresponds to the opening of the U-shape, and the shaft member receiving portion 66 corresponds to the bottom of the U-shape.

[0141] like Figures 12 to 14 As shown, for example, inner wall 62A defines the shaft member receiving portion 66 and opening portion 68. Inner wall 62A includes a plate-like member extending in the axial direction X1. For example, outer wall 62B is located at a position separated from inner wall 62A radially outward about the central axis C1. Outer wall 62B includes a plate-like member extending in the axial direction X1. For example, end wall 62C connects inner wall 62A and outer wall 62B, at least partially defining the internal space H2 of housing 62. End wall 62C includes a plate-like member extending in a direction perpendicular to the axial direction X1. For example, cover portion 62D covers at least a portion of the internal space H2. Cover portion 62D includes a plate-like member extending in a direction perpendicular to the axial direction X1. For example, inner wall 62A, outer wall 62B, and end wall 62C are integrally formed to form internal space H2. For example, the cover 62D is formed separately from the inner wall 62A, the outer wall 62B, and the end wall 62C, and is installed onto the inner wall 62A and the outer wall 62B. The cover 62D is installed onto the inner wall 62A and the outer wall 62B while the internal space H2 of the housing 62 houses at least a portion of the electrical component 58.

[0142] For example, the housing 64 includes a first housing 64A, a second housing 64B, and a third housing 64C. For example, the second housing 64B is configured such that it sandwiches a central axis C1 with the first housing 64A. For example, the third housing 64C is configured in a circumferential direction X3 about the central axis C1 between the first housing 64A and the second housing 64B. For example, at least one battery 64X is housed in at least one of the first housing 64A and the second housing 64B. The at least one battery 64X includes two batteries 64X. It is possible to arbitrarily house at least one battery 64X in at least one of the first housing 64A and the second housing 64B, depending on the number of batteries 64X. The two batteries 64X are housed in the first housing 64A and the second housing 64B, respectively.

[0143] like Figure 8 As shown, the housing limiting member 62X is configured to limit the movement of the housing 62 relative to the shaft member 26. The housing limiting member 62X is mounted to the housing 62, for example, by screws or the like. The housing limiting member 62X includes, for example, a plate-like member extending perpendicularly to the axial direction X1. The housing limiting member 62X is mounted to the generator section 40, for example, at a portion different from the mounting portion to the housing 62, by screws or the like, thereby being mounted to the shaft member 26 in a manner that prevents movement relative to the shaft member 26. The housing limiting member 62X is, for example, mounted to the first limiting member 52C.

[0144] like Figure 4 As shown, the housing 62 is configured to surround at least a portion of the shaft member 26. For example, the shaft member 26 includes a first shaft portion 26X. For example, the housing 62 is disposed on the first shaft portion 26X in an axial direction X1 about a central axis C1. The dimension D1 of the first shaft portion 26X is, for example, the largest dimension of the outer diameter of the outer surface 26B of the shaft member 26 in the direction perpendicular to the axial direction X1.

[0145] For example, shaft member 26 includes a first shaft portion 26X and a second shaft portion 26Y. For example, the second shaft portion 26Y differs from the first shaft portion 26X in the axial direction X1. The second shaft portion 26Y is disposed on the second axial direction A2 side relative to the first shaft portion 26X. For example, the dimension D2 of the second shaft portion 26Y in the radial direction X2 is larger than the dimension D1 of the first shaft portion 26X in the radial direction X2. For example, a power generation unit 40 is provided in the second shaft portion 26Y. The dimension D2 of the second shaft portion 26Y is such that, with the housing 62 disposed on the shaft member 26, the housing 62 cannot move beyond the second shaft portion 26Y in the axial direction X1. Therefore, the housing 62 cannot be inserted into the shaft member 26 from the second shaft portion 26Y toward the first shaft portion 26X in the axial direction X1.

[0146] For example, shaft member 26 includes a third shaft portion 26Z. For example, the third shaft portion 26Z differs from both the first shaft portion 26X and the second shaft portion 26Y in the axial direction X1. The third shaft portion 26Z is disposed on the first axial direction A1 side relative to the first shaft portion 26X. For example, the second shaft portion 26Y and the third shaft portion 26Z are disposed such that they sandwich the first shaft portion 26X. For example, the dimension D3 of the third shaft portion 26Z in the radial direction X2 is larger than the dimension D1 of the first shaft portion 26X in the radial direction X2. For example, a bearing 34 is mounted on the third shaft portion 26Z. The dimension D3 of the third shaft portion 26Z is such that, with the housing 62 disposed on the shaft member 26, the housing 62 cannot move beyond the third shaft portion 26Z in the axial direction X1. Therefore, the housing 62 cannot be inserted into the shaft member 26 from the third shaft portion 26Z toward the first shaft portion 26X in the axial direction X1.

[0147] The shaft member receiving portion 66 receives the shaft member 26. The shaft member 26 is received by the shaft member receiving portion 66 in the radial direction X2 via the opening 68, thereby the housing 62 is disposed on the shaft member 26. The shaft member receiving portion 66 is disposed on the radial inner surface of the inner wall 62A. For example, the shaft member receiving portion 66 is configured to have a shape along at least a portion of the shaft member 26 in the circumferential direction X3 about the central axis C1. For example, when the shaft member receiving portion 66 is configured to have a shape along an arcuate portion in the outer circumferential surface of the shaft member 26, the shaft member receiving portion 66 has a shape corresponding to the arcuate shape of the outer circumferential surface of the shaft member 26. For example, the shaft member receiving portion 66 is configured to have a shape along a portion of the shaft member 26 in the circumferential direction X3 that is more than 90 degrees and less than 200 degrees. In other words, the portion of the shaft member receiving portion 66 that is along the shape of the shaft member 26 has a length in the circumferential direction X3 that is more than 90 degrees and less than 200 degrees. The shaft member receiving portion 66 is configured, for example, as a portion that is substantially 180 degrees along the shaft member 26 in the circumferential direction X3.

[0148] The opening 68 communicates with the shaft member receiving portion 66 such that the shaft member 26 is received by the shaft member receiving portion 66 via the opening 68. The opening 68 is connected to the shaft member receiving portion 66 in a radial direction X2 about the central axis C1. For example, the opening 68 is arranged in the circumferential direction X3 at a portion different from the portion of the shaft member receiving portion 66 along the shaft member 26, and in the axial direction X1 about the central axis C1, it is configured to extend from one end of the housing 62 to the other. The opening 68 is configured to extend from the inner wall 62A to the outer wall 62B in a radial direction X2.

[0149] An opening 68 is provided on the radially inner surface of the inner wall 62A where the shaft member receiving portion 66 is not disposed. The opening 68 includes a first side portion 68A and a second side portion 68B. The shaft member receiving portion 66 is disposed adjacent to the first side portion 68A on the radially inner surface of the inner wall 62A, and the second side portion 68B is disposed adjacent to the shaft member receiving portion 66. In summary, in the circumferential direction X3, the first side portion 68A is disposed at one end of the shaft member receiving portion 66, and the second side portion 68B is disposed at the other end of the shaft member receiving portion 66. The first side portion 68A and the second side portion 68B are arranged parallel to each other.

[0150] For example, opening 68 forms a shaft member passage path 68C through which shaft member 26 can pass. Shaft member passage path 68C is a continuous passage from the outer wall 62B of housing 62 to the inner wall 62A. For example, shaft member 26 is configured to be received by shaft member receiving portion 66 via shaft member passage path 68C. Shaft member 26 passes through shaft member passage path 68C in such a manner as to be received by shaft member receiving portion 66. For example, opening size D4 of opening 68 is greater than or equal to the size D1 of the first shaft portion 26X in the radial direction X2. Opening size D4 of opening 68 is, for example, the distance from the first side portion 68A to the second side portion 68B when viewed from the axial direction X1. Opening size D4 of opening 68 is, for example, larger than the size D1 of the first shaft portion 26X in the radial direction X2. In this embodiment, the first side portion 68A and the second side portion 68B are arranged in parallel, so the opening size D4 is fixed within shaft member passage path 68C. If shaft member 26 passes through shaft member through path 68C, then the opening size D4 of opening 68 may also be partially different within shaft member through path 68C.

[0151] <Connector 70>

[0152] like Figure 8 and Figure 14As shown, for example, at least one connector 70 connects an electrical component 58 housed in a housing 62 to a cable 88 disposed outside the housing 62. For example, at least one connector 70 is disposed in at least one of a first housing portion 64A and a second housing portion 64B. The connector 70 is disposed, for example, in the second housing portion 64B. Alternatively, at least one connector 70 may comprise a plurality of connectors 70, disposed in both the first housing portion 64A and the second housing portion 64B. The connector 70 is electrically connected to at least an electrical substrate 58A. The connector 70 is electrically connected to a storage device 64X. The connecting portion of the connector 70 protrudes from the outer wall 62B of the housing 62. An O-ring is provided on the connector 70 to protect it when the cable 88 is connected. The receiving port of the connector 70 is configured to face a direction perpendicular to the axial direction X1, allowing the cable 88 to be connected from this direction. A portion of the connector 70 protrudes outward from the outer wall 62B. An annular member is provided between the outer wall 62B and the connector 70. The annular component is, for example, an O-ring. The annular component prevents dust, liquids, etc. from entering the receiving part 64 through the gap between the outer wall 62B and the connector 70.

[0153] <Rotating Device 72>

[0154] like Figure 7 and Figure 17 As shown, for example, the hub assembly 20 includes a rotating device 72 for a manually driven vehicle. The rotating device 72 in this embodiment is configured as the hub assembly 20. The rotating device 72 includes a first member 72A, a second member 72B, at least one magnet 74, and at least one magnetic sensor 76. The rotating device 72 includes the first member 72A, the second member 72B, the magnet 74, the magnetic sensor 76, and a magnetic generating member 72X. The magnetic generating member 72X is configured not to rotate relative to the first member 72A and is different from the magnet 74. Therefore, when the first member 72A does not rotate, the magnetic generating member 72X does not rotate. On the other hand, when the first member 72A rotates, the magnetic generating member 72X rotates integrally with the first member 72A. The magnetic generating member 72X is mounted to the electrical board 58A, thereby being configured not to rotate relative to the first member 72A. The magnetic generating member 72X includes an electrical component that generates magnetism. The magnetic generating member 72X includes, for example, an inductor. The magnetic generating member 72X includes, for example, a coil. The magnetic generating component 72X generates magnetism when an electric current flows. The rotating device 72 also includes, for example, an electrical board 58A. The rotating device 72 also includes, for example, a control unit 78.

[0155] The first component 72A has a central axis C1. In this embodiment, the first component 72A is a shaft component 26. The second component 72B rotates relative to the first component 72A about the central axis C1. The second component 72B includes at least one of a hub housing 24 and a sprocket support 32. In this embodiment, the second component 72B includes, for example, a sprocket support 32.

[0156] <Magnetic Sensor 76>

[0157] For example, the magnetic sensor 76 is configured to detect the magnetism of a magnetic component 74X, which is different from that of the magnet 44. The magnetic component 74X is, for example, the magnet 74. The magnetic sensor 76 is disposed on the electrical board 58A. The magnetic sensor 76 is positioned closer to the electrical component 58 in the axial direction X1 than the magnetic shielding member 60. The magnetic sensor 76 is configured to detect the magnetism of the magnet 74 without rotating relative to the first member 72A. Therefore, when the first member 72A does not rotate, the magnetic sensor 76 does not rotate. On the other hand, when the first member 72A rotates, the magnetic sensor 76 rotates integrally with the first member 72A. At least one magnetic sensor 76 is configured to detect the magnetism of at least one magnet 74 without rotating relative to the first member 72A. At least one magnetic sensor 76 is configured not to rotate relative to the first member 72A. The magnetic sensor 76 is configured to not rotate relative to the first member 72A by being mounted to the electrical board 58A. The magnetic sensor 76 is, for example, separately configured from the first member 72A. The magnetic sensor 76 is disposed on the first member 72A in a manner that allows it to rotate integrally with the first member 72A. For example, at least one magnetic sensor 76 is configured in a non-opposing manner relative to at least one magnet 74. The magnetic sensor 76 is configured not to be opposed to the magnet 74 in the axial direction X1. For example, at least one magnetic sensor 76 is disposed in a first region R1 in the radial direction X2.

[0158] like Figure 8 and Figure 15 As shown, at least one magnetic sensor 76 has a detection surface 76X for detecting the magnetism of a magnet 74. A magnetic detection element is disposed on the detection surface 76X. The detection surface 76X is not perpendicular to the magnetization direction M1 of the S and N poles of the at least one magnet 74. For example, the magnetization direction M1 is parallel to the axial direction X1. The detection surface 76X is either inclined relative to the magnetization direction M1 or disposed parallel to the magnetization direction M1. For example, the detection surface 76X is disposed parallel to the magnetization direction M1.

[0159] The magnetic flux density generated by magnet 74 decreases as it moves toward the direction intersecting the magnetization direction M1 and away from magnet 74. Furthermore, the direction of travel of the magnetic field lines of magnet 74 bends toward the direction intersecting the magnetization direction M1 as it moves away from magnet 74. A magnetic sensor 76 is positioned at a location deviating from magnet 74 in the axial direction X1 and in the radial direction X2, thereby enabling the magnetic sensor 76 to efficiently detect the magnetism of magnet 74.

[0160] like Figure 15 and Figure 16 As shown, the magnetic sensor 76 includes a first magnetic sensor 76A and a second magnetic sensor 76B. The first magnetic sensor 76A detects the magnetism of the magnet 74. The second magnetic sensor 76B detects the magnetism of the magnet 74 independently of the first magnetic sensor 76A. The first magnetic sensor 76A and the second magnetic sensor 76B may each have other detection elements, for example. The first magnetic sensor 76A and the second magnetic sensor 76B are disposed separately.

[0161] <Magnet 74>

[0162] like Figure 15 and Figure 16 As shown, at least one magnet 74 is disposed on the second member 72B. The magnet 74 is configured such that when the second member 72B rotates relative to the first member 72A about its central axis C1, the magnet 74 also rotates relative to the first member 72A about its central axis C1. When the second member 72B rotates relative to the first member 72A about its central axis C1, the magnet 74 is configured to rotate integrally with the second member 72B about its central axis C1. The at least one magnet 74 includes, for example, a first magnet 74A and a second magnet 74B. The second magnet 74B is disposed on the opposite side of the first magnet 74A relative to its central axis C1 in the circumferential direction X3. The second magnet 74B is disposed, for example, on the opposite side of the first magnet 74A relative to its central axis C1 in the radial direction X2. In summary, the first magnet 74A and the second magnet 74B are disposed with the central axis C1 between them.

[0163] At least one magnet 74 is positioned radially (X2) about the central axis C1 at a different location from at least one magnetic sensor 76. At least one magnet 74 is positioned radially (X2) without overlapping with at least one magnetic sensor 76 at a different location from at least one magnetic sensor 76. For example, the magnet 74 is positioned radially outward from the magnetic sensor 76 in the radial X2 direction. At least one magnet 74 is positioned axially (X1) about the central axis C1 at a different location from at least one magnetic sensor 76. At least one magnet 74 is positioned axially (X1) without overlapping with at least one magnetic sensor 76 at a different location from at least one magnetic sensor 76. For example, the magnet 74 is positioned axially (X1) towards the magnetic sensor 76 on the first axial direction A1 side. For example, the magnet 74 is positioned axially (X1) at a different location from the electrical substrate 58A. The magnet 74 is positioned axially (X1) at a different location from the electrical substrate 58A at a different location from the electrical substrate 58A. Magnet 74 is disposed, for example, on the first axial side (A1) relative to the electrical substrate 58A in the axial direction (X1). For example, at least one magnet 74 is disposed in a second region (R2) that does not overlap with the first region (R1) in the radial direction (X2). The first region (R1) is, for example, a circular region located radially inward of the end of the innermost magnet 74 in the radial direction (X2). The second region (R2) is the region located between the circle formed by the end of the innermost magnet 74 in the radial direction (X2) and the circle formed by the end of the outermost magnet 74 in the radial direction (X2). The first region (R1) is, for example, a circular region located radially outward of the end of the outermost magnet 74 in the radial direction (X2).

[0164] <Configuration of the magnetic generating component 72X, the magnetic sensor 76, and the magnet 74>

[0165] For example, a magnetic generating component 72X and a magnetic sensor 76 are disposed on an electrical substrate 58A. The magnetism of the magnetic generating component 72X reaches the magnetic sensor 76 in a manner that equally affects the first magnetic sensor 76A and the second magnetic sensor 76B. The first magnetic sensor 76A and the second magnetic sensor 76B are disposed on the surface of the electrical substrate 58A on which the magnetic generating component 72X is disposed. The first magnetic sensor 76A is disposed on the side opposite to the second magnetic sensor 76B with respect to a reference surface P1. The reference surface P1 includes a central axis C1 and passes through the magnetic generating component 72X. The reference surface P1, for example, includes the entire central axis C1. For example, the reference surface P1 passes through the center of the magnetic generating component 72X. The magnetic generating component 72X is disposed on the electrical substrate 58A in a manner that generates magnetism symmetrically with respect to the reference surface P1. For example, the first magnetic sensor 76A and the second magnetic sensor 76B are symmetrically disposed with respect to the reference surface P1. The first magnetic sensor 76A and the second magnetic sensor 76B are symmetrically disposed with respect to the reference surface P1. The detection surface 76X of the first magnetic sensor 76A and the second magnetic sensor 76B are symmetrically arranged with respect to the reference surface P1.

[0166] A first magnetic sensor 76A, a second magnetic sensor 76B, and a magnetic generating component 72X are disposed on a predetermined plane P2. The predetermined plane P2 is a plane orthogonal to a reference plane P1. The predetermined plane P2, for example, includes the surface of the electrical substrate 58A on which the first magnetic sensor 76A, the second magnetic sensor 76B, and the magnetic generating component 72X are disposed. The first magnetic sensor 76A, the second magnetic sensor 76B, and the magnetic generating component 72X are arranged such that they form an isosceles triangle at their respective centers on the predetermined plane P2. The isosceles triangle formed by the first magnetic sensor 76A, the second magnetic sensor 76B, and the magnetic generating component 72X has the magnetic generating component 72X at one vertex, and the first magnetic sensor 76A and the second magnetic sensor 76B at the respective base vertices.

[0167] For example, the first distance Z1 is equal to the second distance Z2. For example, the first distance Z1 is the distance from the first magnetic sensor 76A to the magnetic generating component 72X. For example, the first distance Z1 is the shortest distance from the first magnetic sensor 76A to the magnetic generating component 72X. For example, the first distance Z1 is the distance from the center of the detection surface 76X of the first magnetic sensor 76A to the center of the magnetic generating component 72X. For example, the second distance Z2 is the distance from the second magnetic sensor 76B to the magnetic generating component 72X. For example, the second distance Z2 is the shortest distance from the second magnetic sensor 76B to the magnetic generating component 72X. For example, the second distance Z2 is the distance from the center of the detection surface 76X of the second magnetic sensor 76B to the center of the magnetic generating component 72X.

[0168] <Control Department 78>

[0169] like Figure 16 and Figure 17 As shown, the control unit 78 is configured to determine the rotation of the second member 72B relative to the first member 72A based on the magnetism of the magnet 74 detected by the magnetic sensor 76. The control unit 78 includes an arithmetic processing unit that executes a predetermined control program. The arithmetic processing unit includes, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The control unit 78 may include one or more microcomputers. The control unit 78 may include multiple arithmetic processing units separately configured in multiple locations. For example, the control unit 78 also includes a storage unit. The storage unit stores information for various control programs and various control processes. The storage unit includes, for example, non-volatile memory and volatile memory. Non-volatile memory includes, for example, at least one of ROM (Read-Only Memory), EPROM (Erasable Programmable Read Only Memory), EEPROM (Electrically Erasable Programmable Read-Only Memory), and flash memory. Volatile memory includes, for example, RAM (Random Access Memory).

[0170] The control unit 78 is electrically connected to the first magnetic sensor 76A and the second magnetic sensor 76B, so that the magnetic fields detected by the first magnetic sensor 76A and the second magnetic sensor 76B are input as signals. The control unit 78 is electrically connected to an external electrical component 16 disposed outside the hub assembly 20 via an output control circuit 78A. The control unit 78 outputs information to the external electrical component 16 related to the rotation of the second member 72B relative to the first member 72A. The output control circuit 78A is electrically connected to the external electrical component 16 via a cable 88. The electrical component 58 is electrically connected to the external electrical component 16 by the cable 88. The external electrical component 16 may include, for example, a component for a manually driven vehicle that is different from the hub assembly 20. The external electrical component 16 may include, for example, a drive unit for a manually driven vehicle. The output control circuit 78A is a circuit that operates in a stable manner based on the electrical output of the control unit 78. The control unit 78 is mounted to the electrical board 58A, for example, by being powered from the generator 40 via a protection circuit 78B. The protection circuit 78B operates to stabilize the power supply to the control unit 78.

[0171] <Cable 88>

[0172] like Figure 4 and Figure 5 As shown, for example, cable 88 is electrically connected to electrical component 58. For example, cable 88 is connected to control unit 78. For example, cable 88 transmits signals from magnetic sensor 76 to the outside of hub assembly 20. For example, cable 88 transmits power generated by generator 40 to the outside of hub assembly 20. For example, cable 88 is configured inside hub housing 24 along hub shaft 22. Cable 88 is configured, for example, to extend axially X1 along hub shaft 22 inside hub housing 24 on the outer surface of hub shaft 22. Wiring portion 94 extending axially X1 for configuring cable 88 may be provided on the outer surface of hub shaft 22. Wiring portion 94 includes, for example, a groove 94A extending axially X1. Wiring portion 94 may also be configured inside hub housing 24 such that cable 88 passes through hollow portion of shaft member 26.

[0173] For example, cable 88 has a first surface 88X facing radially inward in a receiving portion 88A. The receiving portion 88A is the part of cable 88 housed inside the hub housing 24. The receiving portion 88A is, for example, the part of cable 88 housed inside the hub assembly 20. For example, the first surface 88X extends from the receiving portion 88A to the exposed portion 88B. The exposed portion 88B is the part of cable 88 exposed to the outside of the hub housing 24. The exposed portion 88B exposes to the outside of the hub assembly 20. For example, cable 88 has a second surface 88Y opposite to the first surface 88X. For example, the second surface 88Y extends from the receiving portion 88A to the exposed portion 88B.

[0174] <Cable guide section 90>

[0175] like Figures 2 to 4 As shown, for example, cable 88 is guided by cable guide 90 to extend radially X2 outside hub housing 24. For example, cable 88 is guided by at least one cable guide 90 to extend radially X2 around central axis C1. Cable guide 90 guides cable 88 such that cable 88 does not contact at least one of hub housing 24 and sprocket support 32. At least one cable guide 90 is configured to be disposed axially X1 between first frame abutment end face 22B and second frame abutment end face 22C, and guides cable 88. Cable guide 90 is configured to guide cable 88 such that cable 88 passes axially X1 between frame 14 of manual drive vehicle 10 and end 26C of shaft member 26. At least one cable guide 90 is at least partially disposed on at least one end cap 28. For example, at least one cable guide 90 is disposed on end cap 28. In this embodiment, cable guide 90 is disposed on end cap 28X. In this embodiment, the cable guide 90 is a recess provided on the first frame abutment end face 22B and extending inward from the first frame abutment end face 22B toward the axial direction X1. If the shaft member 26 does not include the end cap 28, the cable guide 90 may also be provided at the end 26C of the shaft member 26. A portion of the cable guide 90 is disposed, for example, inside the end cap 28X in the axial direction X1. The cable 88 passes through the recess of the cable guide 90 from inside the end cap 28X and is led out. When the cable 88 is led out from the recess of the cable guide 90, the cable 88 contacts the end of the recess of the cable guide 90. The portion of the cable guide 90 in which the cable 88 contacts is the abutment portion 90B. By the contact between the cable 88 and the abutment portion 90B, contact between the cable 88 and rotating bodies such as the sprocket support 32 or the hub housing 24 can be prevented. When the cable 88 is guided by the groove 94A and positioned at the end of the hub shaft 22, the hub assembly 20 may, for example, include a component that abuts against the second surface 88Y of the cable 88. The component abutting against the second surface 88Y of the cable 88 includes an annular member through which the cable 88 and the hub shaft 22 pass. For example, by mounting the annular member to the hub shaft 22, separation of the cable 88 from the hub shaft 22 can be prevented. The annular member abutting against the second surface 88Y of the cable 88 functions as an abutment portion 90B.

[0176] At least one cable guide 90 extends at least partially through the hub shaft 22 in a radial direction X2 about the central axis C1. For example, the cable guide 90 is provided in a hollow portion, extending through the peripheral wall portion 22A. The at least one cable guide 90 may be a hole extending through the peripheral wall portion 22A. For example, the at least one cable guide 90 is at least one cutout 90A provided in the first frame abutment end face 22B and the second frame abutment end face 22C. The cutout 90A is formed by transversely cutting and severing a portion of the peripheral wall portion 22A.

[0177] For example, the cable guide 90 has an abutment portion 90B. The cable 88 abuts against the abutment portion 90B. The abutment portion 90B includes a portion in the inner surface of the end cap 28 that abuts against the guided portion of the cable 88. The abutment portion 90B is configured to be located on the first axial side A1 relative to the sprocket support 32. The cable guide 90 can guide the cable 88 through the abutment portion 90B such that the portion of the cable 88 guided in the radial direction X2 is located on the first axial side A1 relative to the sprocket support 32.

[0178] <Auxiliary Component 92>

[0179] like Figures 2 to 4 As shown, the auxiliary member 92 is configured to guide at least a portion of the exposed portion 88B radially X2 about the central axis C1. The auxiliary member 92 is mounted, for example, to the hub shaft 22. The auxiliary member 92 is mounted, for example, to the end cap 28. The auxiliary member 92 is disposed between the first frame abutment end face 22B and the second frame abutment end face 22C. For example, the auxiliary member 92 is formed of a linear member. For example, the hub shaft 22 includes at least one of a hole 22X and a recess 22Y into which the end of the linear member is inserted. At least one of the hole 22X and the recess 22Y of the hub shaft 22 is formed, for example, in the end cap 28. The end of the linear member is inserted into at least one of the hole 22X and the recess 22Y, thereby mounting the auxiliary member 92 to the hub shaft 22. The hub shaft 22 includes both the hole 22X and the recess 22Y.

[0180] like Figure 20 and Figure 21 As shown, for example, auxiliary member 92 includes a hub shaft mounting portion 92A. The hub shaft mounting portion 92A is inserted into at least one of the hole 22X and the recess 22Y of the hub shaft 22. For example, auxiliary member 92 includes a first cable support portion 92B. The first cable support portion 92B contacts a first surface 88X. For example, auxiliary member 92 includes a second cable support portion 92C. The second cable support portion 92C contacts a second surface 88Y. The hub shaft mounting portion 92A, the first cable support portion 92B, and the second cable support portion 92C are integrally formed from a linear member.

[0181] For example, the auxiliary component 92 is configured to switch from one of the first state and the second state to the other. Figure 21 In the diagram, the auxiliary member 92 in the first state is shown in solid line. For example, the first state is one in which at least a portion of the exposed portion 88B of the cable 88 is guided radially X2. In the first state, the auxiliary member 92 guides the cable 88 radially X2 with the exposed portion 88B away from the central axis C1. Figure 21 In the diagram, the auxiliary member 92 in the second state is shown with a double-dotted line. For example, in the second state, at least a portion of the exposed portion 88B of the cable 88 is guided axially towards X1. In the second state, the auxiliary member 92 guides the cable 88 towards the radial direction X2 inwards with the exposed portion 88B close to the central axis C1. In the second state, the auxiliary member 92 guides the exposed portion 88B of the cable 88 axially towards X1.

[0182] For example, with the hub assembly 20 installed on the frame 14, the auxiliary member 92 is set to a first state. For example, with the sprocket 12 installed on the sprocket support 32 and with the sprocket 12 removed from the sprocket support 32, the auxiliary member 92 is set to a second state. Switching between the first and second states can be achieved, for example, by an operator pressing or pulling the auxiliary member 92.

[0183] <Assembly method for wheel hub assembly 20>

[0184] In the shaft member 26, a tool engaging portion 84 is provided on the surface 84A facing the axial direction X1 in the end 26C of the shaft member 26 about the central axis C1 of the shaft member 26. The surface 84A facing the axial direction X1 is, for example, the end face of the shaft member 26. The tool engaging portion 84 can engage the tool T2.

[0185] For example, the tool engagement portion 84 includes at least one recess 86 recessed in the axial direction X1. For example, the recess 86 includes a tool engagement surface 84B facing the axial direction X1. At least a portion of the tool engagement surface 84B is formed perpendicular to the axial direction X1. For example, the at least one recess 86 continues radially from the outer surface 26B to the inner surface 26A. The recess 86 opens, for example, at least radially X2. The recess 86 opens, for example, axially X1.

[0186] like Figure 19As shown, for example, at least one recess 86 includes a first recess 86A and a second recess 86B. For example, the second recess 86B is disposed on the opposite side of the first recess 86A in the circumferential direction X3 about the central axis C1. The second recess 86B is disposed, for example, on the opposite side of the first recess 86A in the radial direction X2 about the central axis C1. The first recess 86A and the second recess 86B are arranged to clamp the central axis C1. In this embodiment, the recess 86 of the tool engaging portion 84 includes... Figure 7 The positioning recess 82B of the positioning member 80 is shown. The positioning member 80 is mounted to the end cover 28X and disposed in the tool engagement portion 84. The second portion 80B of the positioning member 80 is disposed in the recess 86 of the tool engagement portion 84. The recess 86 of the tool engagement portion 84 can also be provided independently of the positioning recess 82B.

[0187] Reference Figure 4 , Figure 5 , Figure 9 as well as Figure 22 The assembly method of the wheel hub assembly 20 is described below. The assembly method of the wheel hub assembly 20 includes a first process, a second process, a third process, a fourth process, a fifth process, and a sixth process.

[0188] The first step is to arrange the power generation unit 40 and the housing restraint member 62X on the shaft member 26. In the first step, after the power generation unit 40 is installed onto the second shaft portion 26Y of the shaft member 26, the housing restraint member 62X is installed onto the power generation unit 40.

[0189] The second step is the process of configuring the housing 62 on the shaft member 26. In this second step, after the housing 62 is configured radially X2 on the first shaft portion 26X of the shaft member 26, the housing 62 is installed onto the housing retaining member 62X. A lead wire 50B, which is drawn from the winding 50A, is electrically connected to the housing 62. A cable 88 is connected to the connector 70 of the housing 62.

[0190] The third step is to mount the hub housing 24 on the shaft member 26. The hub housing 24, with magnet 44, back yoke 42C and additional bearing 30A mounted on its inner surface, is mounted on the shaft member 26.

[0191] The fourth step is to install the additional end cap 30 on the shaft member 26. In this fourth step, the axial X1 position of the additional bearing 30A disposed on the inner surface of the hub housing 24 is positioned. In this fourth step, the tool T2 engages with the tool engagement part 84, thereby suppressing rotation of the shaft member 26 at least in the circumferential X3 direction. With the rotation of the shaft member 26 in the circumferential X3 direction suppressed, the additional end cap 30 is installed on the shaft member 26. Because the rotation of the shaft member 26 in the circumferential X3 direction can be suppressed by the tool engagement part 84, it is easy to install the additional end cap 30 on the shaft member 26.

[0192] The fifth step is the installation of the torque transmission structure 36 onto the hub housing 24. In this fifth step, with the spline of tool T1 engaged with the tool engagement part 36C, tool T1 rotates circumferentially X3, thereby installing the torque transmission structure 36 onto the hub housing 24.

[0193] The sixth step is the installation of the end cap 28X on the shaft member 26. In this sixth step, the cable 88 connected to the connector 70 is led out to the outside of the hub housing 24 through the hollow portion of the end cap 28X. With the cable 88 passing through the hollow portion of the end cap 28X, the end cap 28X is installed on the shaft member 26.

[0194] <Method for determining rotation performed by control unit 78>

[0195] Reference Figure 23 and Figure 24 The rotation determination method performed by the control unit 78 will be explained.

[0196] The magnetic sensor 76 is configured, for example, to output a detection signal to the control unit 78 when magnetism is detected, and to output a non-detection signal to the control unit 78 when magnetism is not detected. The magnetic sensor 76 is configured, for example, to output a detection signal to the control unit 78 when the magnetic flux density input to the detection surface 76X is above a predetermined threshold. The magnetic sensor 76 is configured, for example, to output a non-detection signal to the control unit 78 when the magnetic flux density input to the detection surface 76X is below a predetermined threshold. The detection signal and the non-detection signal can be voltage values. One of the detection signal and the non-detection signal can be a high signal, or the other can be a low signal. A low signal can be 0V. The control unit 78 is configured to determine the rotation of the second member 72B relative to the first member 72A based on changes in the outputs from the first magnetic sensor 76A and the second magnetic sensor 76B.

[0197] When the second component 72B rotates, the timing of the magnetism detection of magnet 74 by the first magnetic sensor 76A differs from the timing of the magnetism detection of magnet 74 by the second magnetic sensor 76B. The difference between the timing of the magnetism detection of magnet 74 by the first magnetic sensor 76A and the timing of the magnetism detection of magnet 74 by the second magnetic sensor 76B corresponds to the phase difference between the first magnetic sensor 76A and the second magnetic sensor 76B about the central axis C1. In short, the difference between the timing of the magnetism detection of magnet 74 by the first magnetic sensor 76A and the timing of the magnetism detection of magnet 74 by the second magnetic sensor 76B corresponds to the positions of the first magnetic sensor 76A and the second magnetic sensor 76B in the circumferential direction X3. The phase difference between the first magnetic sensor 76A and the second magnetic sensor 76B about the central axis C1 is, for example, less than the phase difference between the first magnet 74A and the second magnet 74B about the central axis C1. The phase difference between the first magnet 74A and the second magnet 74B about the central axis C1 is, for example, 180 degrees.

[0198] When the second component 72B rotates, the first magnetic sensor 76A can be configured to output a detection signal for a first predetermined period. When the second component 72B rotates, the second magnetic sensor 76B can be configured to output a detection signal for a second predetermined period. For example, the first predetermined period is substantially equal to the second predetermined period. The phase difference between the first magnetic sensor 76A and the second magnetic sensor 76B with respect to the central axis C1 is set such that, for example, when the first magnetic sensor 76A outputs a detection signal, the output of the second magnetic sensor 76B changes from a non-detection signal to a detection signal.

[0199] exist Figure 23 In the diagram, the change in magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A is shown by a solid line, and the change in magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B is shown by a double-dotted line.

[0200] Time t11 indicates the moment when the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A becomes above a predetermined threshold due to the rotation of the second member 72B in a predetermined direction. At time t11, the output of the first magnetic sensor 76A changes from a non-detection signal to a detection signal. At time t11, the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B is below the predetermined threshold; therefore, the output of the second magnetic sensor 76B is a non-detection signal.

[0201] Time t12 indicates the moment when the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B becomes above a predetermined threshold due to further rotation of the second member 72B in a predetermined direction. At time t12, the output of the second magnetic sensor 76B changes from a non-detection signal to a detection signal. At time t12, the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A is maintained above the predetermined threshold, therefore the output of the first magnetic sensor 76A is maintained as a detection signal.

[0202] Time t13 indicates the moment when the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A falls below a predetermined threshold due to further rotation of the second member 72B in a predetermined direction. At time t13, the output of the first magnetic sensor 76A changes from a detection signal to a non-detection signal. At time t13, the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B is maintained above the predetermined threshold, therefore the output of the second magnetic sensor 76B is maintained as a detection signal.

[0203] Time t14 indicates the moment when the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B falls below a predetermined threshold due to further rotation of the second member 72B in a predetermined direction. At time t14, the output of the second magnetic sensor 76B changes from a detection signal to a non-detection signal. At time t14, the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A is maintained at below the predetermined threshold, therefore the output of the first magnetic sensor 76A is maintained as a non-detection signal.

[0204] Figure 23 The diagram shows the second component 72B rotating relative to the first component 72A in a predetermined direction. However, when the second component 72B rotates relative to the first component 72A in a direction opposite to the predetermined direction, the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A, the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B, the output of the first magnetic sensor 76A, and the output of the second magnetic sensor 76B change in a manner from time t14 to time t11.

[0205] The control unit 78 is configured, for example, to determine the rotation of the second member 72B relative to the first member 72A based on the output of the first magnetic sensor 76A when the output of the second magnetic sensor 76B changes. If the change in the outputs of the first magnetic sensor 76A and the second magnetic sensor 76B is in a first mode, the control unit 78 determines that the second member 72B is rotating relative to the first member 72A in a predetermined direction. If the change in the outputs of the first magnetic sensor 76A and the second magnetic sensor 76B is in a second mode, the control unit 78 determines that the second member 72B is rotating relative to the first member 72A in a direction opposite to the predetermined direction. Alternatively, the control unit 78 is configured not to determine the rotation of the second member 72B relative to the first member 72A if the change in the outputs of the first magnetic sensor 76A and the second magnetic sensor 76B is different from both the first and second modes.

[0206] The first mode is a mode in which the output of the first magnetic sensor 76A is a detection signal when the output of the second magnetic sensor 76B changes from a non-detection signal to a detection signal, and the output of the first magnetic sensor 76A is a non-detection signal when the output of the second magnetic sensor 76B changes from a detection signal to a non-detection signal. In the first mode, at time t12, the output of the first magnetic sensor 76A is a detection signal when the output of the second magnetic sensor 76B changes from a non-detection signal to a detection signal. Then, at time t14, the output of the first magnetic sensor 76A is a non-detection signal when the output of the second magnetic sensor 76B changes from a detection signal to a non-detection signal.

[0207] The second mode is a mode in which the output of the first magnetic sensor 76A is a non-detection signal when the output of the second magnetic sensor 76B changes from a non-detection signal to a detection signal, and the output of the first magnetic sensor 76A is a detection signal when the output of the second magnetic sensor 76B changes from a detection signal to a non-detection signal. In the second mode, at time t14, the output of the first magnetic sensor 76A is a non-detection signal when the output of the second magnetic sensor 76B changes from a non-detection signal to a detection signal. Then, at time t12, the output of the first magnetic sensor 76A is a detection signal when the output of the second magnetic sensor 76B changes from a detection signal to a non-detection signal.

[0208] Reference Figure 24 This illustrates an example of how the control unit 78 determines the rotational direction of the second member 72B relative to the first member 72A. For example, when the control unit 78 is supplied with power, the processing in step S11 begins. Figure 24 When the processing ends, the processing of step S11 will start again after a specified period.

[0209] In step S11, the control unit 78 determines whether the output of the second magnetic sensor 76B changes from a non-detection signal to a detection signal. If the output of the second magnetic sensor 76B does not change from a non-detection signal to a detection signal, the control unit 78 terminates the process. If the output of the second magnetic sensor 76B changes from a non-detection signal to a detection signal, the control unit 78 proceeds to step S12.

[0210] In step S12, the control unit 78 determines whether the output of the first magnetic sensor 76A is a detection signal. If the output of the first magnetic sensor 76A is a detection signal, the control unit 78 proceeds to step S13. If the output of the first magnetic sensor 76A is not a detection signal, the control unit 78 proceeds to step S16.

[0211] In step S13, the control unit 78 determines whether the output of the second magnetic sensor 76B has changed from a detection signal to a non-detection signal. If the output of the second magnetic sensor 76B has not changed from a detection signal to a non-detection signal, the control unit 78 executes step S13 again. If the output of the second magnetic sensor 76B has changed from a detection signal to a non-detection signal, the control unit 78 proceeds to step S14.

[0212] In step S14, the control unit 78 determines whether the output of the first magnetic sensor 76A is a non-detection signal. If the output of the first magnetic sensor 76A is a non-detection signal, the control unit 78 proceeds to step S15. If the output of the first magnetic sensor 76A is not a non-detection signal, the control unit 78 terminates the process. In step S15, the control unit 78 terminates the process after determining that the second member 72B is rotating relative to the first member 72A in a predetermined direction. If the output of the first magnetic sensor 76A is not a non-detection signal in step S14, the control unit 78 does not determine the rotation direction of the second member 72B relative to the first member 72A.

[0213] In step S16, the control unit 78 determines whether the output of the second magnetic sensor 76B has changed from a detection signal to a non-detection signal. If the output of the second magnetic sensor 76B has not changed from a detection signal to a non-detection signal, the control unit 78 executes step S16 again. If the output of the second magnetic sensor 76B changes from a detection signal to a non-detection signal, the control unit 78 proceeds to step S17.

[0214] In step S17, the control unit 78 determines whether the output of the first magnetic sensor 76A is a detection signal. If the output of the first magnetic sensor 76A is a detection signal, the control unit 78 proceeds to step S18. If the output of the first magnetic sensor 76A is not a detection signal, the control unit 78 terminates the process. In step S18, the control unit 78 terminates the process after determining that the second member 72B rotates relative to the first member 72A in a direction opposite to a predetermined direction. In step S17, if the output of the first magnetic sensor 76A is not a detection signal, the control unit 78 does not determine the rotation direction of the second member 72B relative to the first member 72A.

[0215] <Second Implementation>

[0216] Reference Figure 25 The hub assembly 20 of the second embodiment will be described. The hub assembly 20 of the second embodiment is the same as the hub assembly 20 of the first embodiment except for the configuration of the power generation device 42 and the housing 62. Therefore, the same reference numerals are used for the components shared with the first embodiment, and repeated descriptions are omitted.

[0217] <Power Generation Unit 42>

[0218] The power generation device 42 of this embodiment includes a bobbin 46, a winding 50A, a lead wire 50B, an electrical component 58, and a conductor 96. The power generation device 42 of this embodiment is the same as the power generation device 42 of the first embodiment, except that it includes the electrical component 58 and the conductor 96.

[0219] <Conductor 96>

[0220] For example, conductor 96 extends along an axial direction X1 about the central axis C1 of spool 46. Conductor 96 is mounted to a first flange 46B of spool 46, configured to extend beyond the limiting member 52 from the first flange 46B. Conductor 96 is configured to protrude toward a first axial direction A1. Conductor 96 is mounted to a protrusion 48. Conductor 96 may be omitted from at least one of the first protrusion 48A and the second protrusion 48B, provided it can extend beyond the limiting member 52 from the first flange 46B.

[0221] Conductor 96 includes a first portion 96X and a second portion 96Y. Conductor 96 is electrically connected to the first portion 96X via a lead 50B and to the second portion 96Y via an electrical component 58. For example, the first portion 96X is disposed at a protrusion 48 of the first flange 46B. The lead 50B extends to the protrusion 48, thereby being electrically connected to the first portion 96X.

[0222] Conductor 96 is at least one of connector pin 96A, socket 96B, and busbar. Conductor 96 has higher rigidity, for example, compared to cable 88. At least one of connector pin 96A, socket 96B, and busbar protrudes from first flange 46B toward first axial direction A1 in a manner parallel to axial direction X1. In this embodiment, conductor 96 is connector pin 96A. Connector pin 96A includes, for example, exposed electrodes. Connector pin 96A is electrically connected to socket 96B, for example, by inserting into socket 96B through the exposed electrodes.

[0223] <Electrical Components 58>

[0224] The electrical component 58 of this embodiment includes a socket 96B connected to the second portion 96Y. The electrical component 58 of this embodiment is identical to the electrical component 58 of the first embodiment, except for the point including the socket 96B. The socket 96B is connected to the second portion 96Y of the connector pin 96A. The receiving port of the socket 96B faces the second axis A2 and is disposed on the additional electrical substrate 58Y in a manner overlapping with the connector pin 96A when viewed from the axial direction X1. The socket 96B causes the housing 62 to move towards the second axis A2 relative to the power generation device 42 disposed on the shaft member 26, thereby configuring the connector pin 96A and the socket 96B to connect.

[0225] <Outer Shell 62>

[0226] In the housing 62 of this embodiment, a through hole 62E is provided in the end wall 62C along the axial direction X1. The housing 62 of this embodiment is the same as the housing 62 of the first embodiment except for the through hole 62E in the end wall 62C. The connector pin 96A passes through the through hole 62E. The connector pin 96A protrudes from the end wall 62C toward the first axial direction A1, for example, via the through hole 62E. The connector pin 96A protrudes toward the receiving portion 64 about the end wall 62C along the axial direction X1, for example, via the through hole 62E. A portion of the socket 96B may also protrude out of the housing 62 via the through hole 62E. When a portion of the socket 96B protrudes out of the housing 62, the connector pin 96A connects to the socket 96B on the second axial direction A2 side relative to the end wall 62C without protruding from the end wall 62C toward the first axial direction A1.

[0227] <Example of Change>

[0228] The descriptions of the various embodiments are illustrative of the possible arrangements of the wheel hub assembly according to this disclosure and are not intended to limit the arrangements. The wheel hub assembly according to this disclosure can be arranged in ways such as variations of the embodiments shown below and combinations of at least two mutually consistent variations. In the following variations, portions shared with the embodiments are labeled with the same reference numerals as those in the embodiments, and their descriptions are omitted.

[0229] • The limiting member 52 can also be installed to the shaft member 26 by methods other than welding. The limiting member 52 can also be installed to the shaft member 26, for example, by a different component than the limiting member 52, such as a screw or nut.

[0230] • The lead wire guide 54 may also be provided separately from the spool 46. When the lead wire guide 54 is provided separately from the spool 46, the lead wire guide 54 may also be installed on the spool 46 in a manner that allows it to be detached from the spool 46. Alternatively, the lead wire guide 54 may not be provided on the spool 46 but on the lead wire guide configuration section 56 of the limiting member 52.

[0231] The connecting part 36A can be installed onto the wheel hub housing 24 in a manner that prevents it from rotating relative to the wheel hub housing 24, or the installation method onto the wheel hub housing 24 can be appropriately modified. For example, the connecting part 36A can be installed onto the wheel hub housing 24 by pressing or serrated engagement.

[0232] The connecting part 36A can be installed to the second one-way clutch part 38B in a manner that prevents it from rotating relative to the second one-way clutch part 38B, or the installation method to the second one-way clutch part 38B can be appropriately modified. For example, the connecting part 36A can be installed to the second one-way clutch part 38B by pressing or by sawtooth engagement.

[0233] ·like Figure 26 As shown, the first one-way clutch portion 38A may also be configured radially X2 further inward than at least a portion of the second one-way clutch portion 38B. In this modified example, the second one-way clutch portion 38B corresponds to the connecting portion 36A. The second one-way clutch portion 38B is engaged with the hub housing 24, for example, by screws. In this modified example, a tool engaging portion 36C is provided on the outer surface of the second one-way clutch portion 38B. The second one-way clutch portion 38B in this modified example includes a protrusion 36B. In this modified example, the tool engaging portion 36C is provided on the outer surface of the protrusion 36B of the second one-way clutch portion 38B.

[0234] ·like Figure 27 As shown, the torque transmission structure 36 may also exclude the one-way clutch 38. Figure 27 In the example shown, the connecting portion 36A is integrally formed with the sprocket support 32. The torque transmission structure 36 of this modified example transmits torque from the sprocket support 32 to the hub housing 24.

[0235] The power generation device 42 may also consist of a first component 42A including a hub housing 24 and a second component 42B including a shaft component 26. In the case where the first component 42A includes a hub housing 24 and the second component 42B includes a shaft component 26, a magnet 44 is mounted to the shaft component 26, and a magnetic shielding member 60 extends outward from the outer surface 26B of the shaft component 26 in the radial direction X2.

[0236] The rotating device 72 may also be a first component 72A comprising at least one of a hub housing 24 and a sprocket support 32, and a second component 72B comprising a shaft component 26. At least one magnetic sensor 76 disposed in the hub housing 24 and the sprocket support 32 detects a magnet 74 disposed in the shaft component 26.

[0237] The magnetic shielding member 60 can also be arranged circumferentially along the entire circumference X3. For example, when viewed from the axial direction X1, the magnetic shielding member 60 only needs to be located at least partially between the magnet 44 and the electrical component 58. If at least a portion of the magnetic shielding member 60 is located between the magnet 44 and the electrical component 58 when viewed from the axial direction X1, the magnetic shielding member 60 can also be mounted to the electrical component 58. If the magnetic shielding member 60 is mounted to the electrical component 58, for example, the magnetic shielding member 60 is disposed at the portion of the electrical component 58 that requires magnetic shielding.

[0238] The magnetic shielding member 60 can be located between the magnet 44 and the electrical component 58 in the axial direction X1, or it can be configured not to contact the magnet 44.

[0239] The magnetic shielding member 60 can be magnetically connected to the back yoke 42C, or it can be formed separately from the back yoke 42C. In the case where the magnetic shielding member 60 is formed separately from the back yoke 42C, the magnetic shielding member 60 may not be in contact with the back yoke 42C.

[0240] The recess 86 of the tool engagement portion 84 at the end 26C of the shaft member 26 can be continuous from the outer surface 26B to the inner surface 26A in the radial direction X2, provided that the tool T2 can engage. For example, the recess 86 of the tool engagement portion 84 may be continuous from the outer surface 26B in the radial direction X2 to a position between the outer surface 26B and the inner surface 26A in the radial direction X2. Alternatively, the recess 86 of the tool engagement portion 84 may be continuous from the inner surface 26A in the radial direction X2 to a position between the outer surface 26B and the inner surface 26A in the radial direction X2.

[0241] The positioning member 80 may also be integrally formed with one of the end cap 28 and the shaft member 26. When the positioning member 80 is integrally formed with one of the end cap 28 and the shaft member 26, for example, the positioning member 80 may be formed as a protrusion provided on one of the end cap 28 and the shaft member 26. When the positioning member 80 is formed as a protrusion provided on one of the end cap 28 and the shaft member 26, the other of the end cap 28 and the shaft member 26 may also include a recess that engages with the protrusion.

A non-circular cross-sectional shape is, for example, a shape with a straight section. An example of a shape with a straight section is a D-shape. When the cross-sectional shape of the shaft member 26 in the direction perpendicular to the central axis C1 is D-shaped, the first dimension of the D-shape in the direction perpendicular to the straight section is different from the second dimension of the D-shape in the direction parallel to the straight section. For example, if the second dimension is the maximum size of the shaft member 26, the opening size D4 of the opening 68 can be larger than the first dimension and less than or equal to the second dimension.
