The housing restriction member 62X is attached to the power generation section 40 by, for example, a screw or the like at a portion different from the attachment portion with the housing 62, so as to be attached to the shaft member 26 in a non-moving manner with respect to the shaft member 26. The housing restriction member 62X is mounted to the first restriction member 52C, for example.

As shown in fig. 4, the housing 62 is configured to enclose at least a portion of the shaft member 26. For example, the shaft member 26 includes a first shaft portion 26X. For example, the first shaft portion 26X is provided with the housing 62 in the axial direction X1 with respect to the center axis C1. The dimension D1 of the first shaft portion 26X is, for example, the largest dimension among the outer diameters of the outer surfaces 26B of the shaft members 26 in the direction perpendicular to the axial direction X1 in the first shaft portion 26X.

For example, the shaft member 26 includes a first shaft portion 26X and a second shaft portion 26Y. For example, the second shaft portion 26Y is different from the first shaft portion 26X in the axial direction X1. The second shaft portion 26Y is disposed on the second shaft A2 side with respect 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, the second shaft portion 26Y is provided with the power generation portion 40. The dimension D2 of the second shaft portion 26Y is a dimension in which the housing 62 cannot move beyond the second shaft portion 26Y in the axial direction X1 in a state in which the housing 62 is disposed on the shaft member 26. Therefore, the housing 62 cannot be inserted into the shaft member 26 in the axial direction X1 from the second shaft portion 26Y toward the first shaft portion 26X.

For example, the shaft member 26 includes a third shaft portion 26Z. For example, the third shaft portion 26Z is different 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 with respect to the first shaft portion 26X. For example, the second shaft portion 26Y and the third shaft portion 26Z are arranged so as to 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 attached to the third shaft portion 26Z. The dimension D3 of the third shaft portion 26Z is a dimension in which the housing 62 cannot move beyond the third shaft portion 26Z in the axial direction X1 in a state in which the housing 62 is disposed on the shaft member 26. Therefore, the housing 62 cannot be inserted into the shaft member 26 in the axial direction X1 from the third shaft portion 26Z toward the first shaft portion 26X.

The shaft member receiving portion 66 receives the shaft member 26. The shaft member 26 is received by the shaft member receiving portion 66 from the radial direction X2 via the opening 68, and the housing 62 is disposed on the shaft member 26. The shaft member receiving portion 66 is disposed on a radially inner surface of the inner wall 62A. For example, the shaft member receiving portion 66 is configured to be shaped along at least a part of the shaft member 26 in the circumferential direction X3 about the center axis C1. For example, in the case where the shaft member receiving portion 66 is configured in a shape along a circular arc-shaped portion in the outer peripheral surface of the shaft member 26, the shaft member receiving portion 66 has a shape corresponding to the circular arc shape of the outer peripheral surface of the shaft member 26. For example, the shaft member receiving portion 66 is formed in a shape along a portion of the shaft member 26 of 90 degrees to 200 degrees in the circumferential direction X3. In other words, the portion of the shaft member receiving portion 66 along the shape of the shaft member 26 has a length corresponding to 90 degrees to 200 degrees in the circumferential direction X3. The shaft member receiving portion 66 is configured in a shape of a portion substantially 180 degrees along the shaft member 26 in the circumferential direction X3, for example.

The opening 68 communicates with the shaft member receiving portion 66 so that the shaft member 26 is received by the shaft member receiving portion 66 through the opening 68. The opening 68 is connected to the shaft member receiving portion 66 in a radial direction X2 with respect to the center axis C1. For example, the opening 68 is disposed at a portion different from a portion of the shaft member receiving portion 66 along the shaft member 26 in the circumferential direction X3, and is configured to reach from one end portion of the housing 62 to the other end portion in the axial direction X1 about the center axis C1. The opening 68 is formed from the inner wall 62A to the outer wall 62B in the radial direction X2.

An opening 68 is provided in a portion of the radially inner surface of the inner wall 62A where the shaft member receiving portion 66 is not provided. The opening 68 includes a first side 68A and a second side 68B. On the radially inner surface of the inner wall 62A, the shaft member receiving portion 66 is disposed adjacent to the first side portion 68A, and the second side portion 68B is disposed adjacent to the shaft member receiving portion 66. In short, 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.

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

< connector 70 >

As shown in fig. 8 and 14, for example, at least 1 connector 70 connects the electrical component 58 housed by the housing 62 and the cable 88 disposed outside the housing 62. For example, at least 1 connector 70 is disposed in at least one of the first housing portion 64A and the second housing portion 64B. The connector 70 is disposed in the second housing 64B, for example. At least 1 of the connectors 70 may include a plurality of connectors 70, and the connectors 70 may be disposed in both the first housing portion 64A and the second housing portion 64B. The connector 70 is electrically connected to at least the electrical substrate 58A. The connector 70 is electrically connected to the electric storage device 64X. The connection portion of the connector 70 is exposed from the outer wall 62B of the housing 62. An O-ring is provided to the connector 70 in order to protect the connector 70 in a state where the connector 70 is connected to the cable 88. The receiving port of the connector 70 is arranged to face in a direction perpendicular to the axial direction X1, so that the cable 88 can be connected from the direction perpendicular to the axial direction X1. A part 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 member is, for example, an O-ring. The annular member prevents dust, liquid, or the like from entering the housing 64 from the gap between the outer wall 62B and the connector 70.

< rotating device 72 >)

As shown in fig. 7 and 17, for example, the hub assembly 20 includes a rotation device 72 for a human powered vehicle. The rotating device 72 of the present embodiment is configured as the hub unit 20. The rotating device 72 includes a first member 72A, a second member 72B, at least 1 magnet 74, and at least 1 magnetic sensor 76. The rotating device 72 includes a first member 72A, a second member 72B, a magnet 74, a magnetic sensor 76, and a magnetic generating member 72X. The magnetism generating member 72X is configured not to rotate relative to the first member 72A, and is different from the magnet 74. Therefore, in the case where the first member 72A does not rotate, the magnetism generating part 72X does not rotate. On the other hand, when the first member 72A rotates, the magnetism generating part 72X rotates integrally with the first member 72A. The magnetism generating member 72X is attached to the electric substrate 58A, and thus is configured not to rotate relative to the first member 72A. The magnetism generating part 72X includes an electric part that generates magnetism. The magnetism generating part 72X includes, for example, an inductor. The magnetism generating part 72X includes, for example, a coil. The magnetism generating member 72X generates magnetism when a current flows. The rotating device 72 further includes, for example, an electric board 58A. The rotating device 72 includes, for example, a control unit 78.

The first member 72A has a central axis C1. The first member 72A of the present embodiment is the shaft member 26. The second member 72B rotates relative to the first member 72A about the central axis C1. The second member 72B includes at least 1 of the hub shell 24 and the sprocket support 32. The second member 72B of the present embodiment includes, for example, the sprocket support 32.

< magnetic sensor 76 >)

For example, the magnetic sensor 76 is configured to detect magnetism of a magnetic member 74X different from the magnet 44. The magnetic member 74X is, for example, a magnet 74. The magnetic sensor 76 is provided on the electrical substrate 58A. The magnetic sensor 76 is disposed closer to the electric component 58 than the magnetic shield member 60 in the axial direction X1. The magnetic sensor 76 is configured to detect magnetism of the magnet 74 without rotating relative to the first member 72A. Therefore, in the case where the first member 72A does not rotate, the magnetic sensor 76 does not rotate. On the other hand, in the case where the first member 72A rotates, the magnetic sensor 76 rotates integrally with the first member 72A. The at least 1 magnetic sensor 76 is configured not to rotate relative to the first member 72A, and detects magnetism of the at least 1 magnet 74. At least 1 magnetic sensor 76 is configured to be non-rotatable relative to first member 72A. The magnetic sensor 76 is configured not to rotate relative to the first member 72A by being mounted to the electrical substrate 58A. The magnetic sensor 76 is formed separately from the first member 72A, for example. The magnetic sensor 76 is provided to the first member 72A so as to be rotatable integrally with the first member 72A, for example. For example, at least 1 magnetic sensor 76 is disposed so as to be non-opposed to at least 1 magnet 74. The magnetic sensor 76 is disposed so as not to face the magnet 74 in the axial direction X1. For example, at least 1 magnetic sensor 76 is disposed in the first region R1 in the radial direction X2.

As shown in fig. 8 and 15, at least 1 magnetic sensor 76 has a detection surface 76X that detects the magnetism of magnet 74. A magnetic detection element is disposed on the detection surface 76X. The detection surface 76X is arranged non-perpendicularly to the magnetization direction M1 in which the S-pole and N-pole of at least 1 magnet 74 are arranged. For example, the magnetization direction M1 is parallel to the axial direction X1. The detection surface 76X is inclined with respect to the magnetization direction M1 or is arranged parallel to the magnetization direction M1. For example, the detection surface 76X is arranged parallel to the magnetization direction M1.

The magnetic flux density of magnetism generated from the magnet 74 decreases as going in a direction intersecting the magnetization direction M1 and separating from the magnet 74. The direction of the magnetic force lines of the magnet 74 is curved in a direction intersecting the magnetization direction M1 as the magnetic force lines are separated from the magnet 74. The magnetic sensor 76 is disposed at a position offset from the magnet 74 in the axial direction X1 and offset from the magnet 74 in the radial direction X2, so that the magnetic sensor 76 can efficiently detect the magnetism of the magnet 74.

As shown in fig. 15 and 16, 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 are each provided with a separate detection element, for example. The first magnetic sensor 76A and the second magnetic sensor 76B are provided separately.

The magnet 74 is configured to rotate around the center axis C1 and the first member 72A when the second member 72B rotates around the center axis C1 and the first member 72A. When the second member 72B rotates around the center axis C1 relative to the first member 72A, the magnet 74 is configured to rotate around the center axis C1 integrally with the second member 72B. The at least 1 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 with respect to the center axis C1 in the circumferential direction X3. The second magnet 74B is disposed on the opposite side of the first magnet 74A with respect to the center axis C1 in the radial direction X2, for example. In other words, the first magnet 74A and the second magnet 74B are arranged with the center axis C1 therebetween.

At least 1 magnet 74 is disposed at a position different from at least 1 magnetic sensor 76 in a radial direction X2 with respect to the center axis C1. At least 1 magnet 74 is disposed at a position different from at least 1 magnetic sensor 76 in the radial direction X2 so as not to overlap with at least 1 magnetic sensor 76. The magnet 74 is disposed radially outward of the magnetic sensor 76 in the radial direction X2, for example. At least 1 magnet 74 is disposed at a position different from at least 1 magnetic sensor 76 in the axial direction X1 with respect to the center axis C1. The at least 1 magnet 74 is disposed at a position different from the at least 1 magnetic sensor 76 in the axial direction X1 so as not to overlap the at least 1 magnetic sensor 76. The magnet 74 is disposed closer to the first axial direction A1 than the magnetic sensor 76 in the axial direction X1, for example. For example, the magnet 74 is disposed at a position different from the electric substrate 58A in the axial direction X1. The magnet 74 is disposed at a position different from the electric substrate 58A in the axial direction X1 so as not to overlap the electric substrate 58A. The magnet 74 is disposed on the first axial direction A1 side with respect to the electric substrate 58A in the axial direction X1, for example. For example, at least 1 magnet 74 is arranged 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 inward in the radial direction X2 from the end of the magnet 74 located innermost in the radial direction X2. The second region R2 is a region between a circle formed at an end of the magnet 74 located innermost in the radial direction X2 and a circle formed at an end of the magnet 74 located outermost in the radial direction X2. The first region R1 is, for example, a circular region located outside the end of the magnet 74 located outermost in the radial direction X2.

< arrangement of magnetic generating means 72X, magnetic sensor 76, and magnet 74 >)

For example, the magnetism generating member 72X and the magnetic sensor 76 are provided on the electric substrate 58A. The magnetism of the magnetism generating member 72X reaches the magnetic sensor 76 so as to affect the first magnetic sensor 76A and the second magnetic sensor 76B in the same manner. The first magnetic sensor 76A and the second magnetic sensor 76B are provided on a surface of the electric substrate 58A on which the magnetism generating member 72X is provided. The first magnetic sensor 76A is disposed on the opposite side of the reference plane P1 from the second magnetic sensor 76B. The reference plane P1 includes the center axis C1 and passes through the magnetism generating member 72X. The reference plane P1 includes, for example, all the center axes C1. For example, the reference plane P1 passes through the center of the magnetism generating part 72X. The magnetism generating member 72X is provided on the electric substrate 58A so as to generate magnetism symmetrically with respect to the reference plane P1. For example, the first magnetic sensor 76A and the second magnetic sensor 76B are symmetrically arranged with respect to the reference plane P1. The first magnetic sensor 76A and the second magnetic sensor 76B are arranged face-symmetrically with respect to the reference plane P1. The detection surface 76X of the first magnetic sensor 76A and the detection surface 76X of the second magnetic sensor 76B of the first magnetic sensor 76A and the second magnetic sensor 76B are arranged symmetrically with respect to the reference plane P1.

The first magnetic sensor 76A, the second magnetic sensor 76B, and the magnetic generating member 72X are disposed on a predetermined plane P2. The predetermined plane P2 is a plane orthogonal to the reference plane P1. The predetermined plane P2 includes, for example, a surface of the electric substrate 58A on which the first magnetic sensor 76A, the second magnetic sensor 76B, and the magnetism generating member 72X are provided. The first magnetic sensor 76A, the second magnetic sensor 76B, and the magnetism generating member 72X are arranged so that their centers form an isosceles triangle on the predetermined plane P2. The isosceles triangle formed by the first magnetic sensor 76A, the second magnetic sensor 76B, and the magnetism generating member 72X is: the magnetism generating part 72X is located at the vertex of the position of the vertex angle, and the first magnetic sensor 76A and the second magnetic sensor 76B are located at the vertex of the position of the bottom angle, respectively.

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

< control section 78 >)

As shown in fig. 16 and 17, 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 device that executes a predetermined control program. The arithmetic processing device includes, for example, a CPU (Central Processing Unit: central processing unit) or an MPU (Micro Processing Unit: micro processing unit). The control section 78 may include 1 or more microcomputers. The control unit 78 may include a plurality of arithmetic processing devices separately disposed at a plurality of locations. For example, the control unit 78 further includes a storage unit. The storage unit stores information for various control programs and various control processes.

The control section 78 is electrically connected to the first magnetic sensor 76A and the second magnetic sensor 76B such that magnetism detected by the first magnetic sensor 76A and the second magnetic sensor 76B is input as a signal. The control portion 78 is electrically connected to the external electrical component 16 provided outside the hub assembly 20 via an output control circuit 78A. The control portion 78 outputs information on the rotation of the second member 72B relative to the first member 72A to the external electrical component 16. 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 a cable 88.

The external electrical component 16 comprises, for example, a drive unit for a human powered vehicle. The output control circuit 78A is a circuit that operates so that the electrical output of the control unit 78 is stable. The control unit 78 is attached to the electric substrate 58A so as to be supplied with electric power from the power generation unit 40 via the protection circuit 78B, for example. The protection circuit 78B operates to stabilize the supply amount of electric power to the control unit 78.

< Cable 88 >)

As shown in fig. 4 and 5, for example, the cable 88 is electrically connected to the electrical component 58. For example, the cable 88 is connected to the control portion 78. For example, the cable 88 transmits the signal of the magnetic sensor 76 to the outside of the hub assembly 20. For example, the cable 88 transmits the electric power generated by the power generation portion 40 to the outside of the hub assembly 20. For example, the cable 88 is disposed along the hub axle 22 inside the hub shell 24. The cable 88 is disposed on the outer surface of the hub axle 22 so as to extend in the axial direction X1 of the hub axle 22 inside the hub shell 24, for example. A wiring portion 94 extending in the axial direction X1 for disposing the cable 88 may be provided on the outer surface of the hub shaft 22. The wiring portion 94 includes, for example, a groove 94A extending in the axial direction X1. The wiring portion 94 may be disposed inside the hub shell 24 such that the cable 88 passes through the hollow portion of the shaft member 26.

For example, the cable 88 has a first face 88X facing radially inward in the housing portion 88A. The housing portion 88A is a portion of the cable 88 that is housed inside the hub shell 24. The housing portion 88A is, for example, a portion of the cable 88 that is housed inside the hub assembly 20. For example, the first face 88X extends from the housing portion 88A to the exposed portion 88B. The exposed portion 88B is a portion of the cable 88 that is exposed to the outside of the hub shell 24. The exposed portion 88B is exposed to the outside of the hub assembly 20. For example, the cable 88 has a second face 88Y on the opposite side from the first face 88X. For example, the second face 88Y extends from the housing portion 88A to the exposed portion 88B.

< Cable guide 90 >)

As shown in fig. 2 to 4, for example, the cable 88 is guided by the cable guide 90 to extend in the radial direction X2 outside the hub shell 24. For example, the cable 88 is guided by at least 1 cable guide 90 to extend in the radial direction X2 of the center axis C1. The cable guide 90 guides the cable 88 such that the cable 88 does not contact at least one of the hub shell 24 and the sprocket support 32. At least 1 cable guide portion 90 is provided between the first frame contact end surface 22B and the second frame contact end surface 22C in the axial direction X1, and guides the cable 88. The cable guide 90 is configured to guide the cable 88 such that the cable 88 passes between the frame 14 of the manually driven vehicle 10 and the end 26C of the shaft member 26 in the axial direction X1. At least 1 cable guide 90 is at least partially disposed in at least 1 end cap 28. For example, at least 1 cable guide 90 is provided to the end cap 28. The cable guide 90 of the present embodiment is provided in the end cover 28X. In the present embodiment, the cable guide 90 is a concave portion provided on the first frame contact end surface 22B and directed inward in the axial direction X1 from the first frame contact end surface 22B. In the case where 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 part of the cable guide 90 is disposed inside the end cover 28X in the axial direction X1, for example. The cable 88 passes from the inside of the end cover 28X through the recess of the cable guide 90 and is led out. When the cable 88 is led out from the concave portion of the cable guide portion 90, the cable 88 contacts the end portion of the concave portion of the cable guide portion 90. The portion of the cable guide portion 90 that the cable 88 contacts is an abutting portion 90B. By the contact of the cable 88 with the contact portion 90B, the contact of the cable 88 with the sprocket support 32, the hub shell 24, or other rotating bodies can be suppressed. When the cable 88 is guided by the groove 94A and disposed at the end of the hub axle 22, the hub unit 20 may include a member that abuts against the second surface 88Y of the cable 88, for example. The member abutting the second surface 88Y of the cable 88 includes an annular member through which the cable 88 and the hub axle 22 pass. For example, by attaching the annular member to the hub axle 22, the cable 88 can be restrained from being separated from the hub axle 22. The annular member of the member that abuts the second surface 88Y of the cable 88 has a function of an abutment portion 90B.

At least 1 cable guide 90 at least partially penetrates the hub shaft 22 in a radial direction X2 with respect to the center axis C1. For example, the cable guide portion 90 is provided in a hollow portion, and penetrates the peripheral wall portion 22A. At least 1 cable guide portion 90 may be a hole penetrating the peripheral wall portion 22A. For example, at least 1 cable guide portion 90 is at least 1 cutout portion 90A provided in the first frame abutment end surface 22B and the second frame abutment end surface 22C. The cutout portion 90A is formed so as to intersect and intercept a part of the peripheral wall portion 22A.

For example, the cable guide portion 90 has an abutment portion 90B. The cable 88 abuts against the abutment portion 90B. The abutment 90B includes a portion of the inner surface of the end cap 28 that abuts the guided portion of the cable 88. The abutment portion 90B is disposed closer to the first axial direction A1 than the sprocket support 32. The cable guide portion 90 can guide the cable 88 by the abutment portion 90B such that a portion of the cable 88 that is guided in the radial direction X2 is located closer to the first axial direction A1 than the sprocket support 32.

< auxiliary Member 92 >)

As shown in fig. 2 to 4, the auxiliary member 92 is configured to guide at least a part of the exposed portion 88B in the radial direction X2 with respect to the center axis C1. The auxiliary member 92 is mounted to the hub axle 22, for example. The auxiliary member 92 is mounted to the end cover 28, for example. The auxiliary member 92 is disposed between the first frame abutment end surface 22B and the second frame abutment end surface 22C. For example, the auxiliary member 92 is formed of a linear member. For example, the hub axle 22 includes at least 1 of the hole 22X and the recess 22Y into which the end of the wire-like member is inserted. At least 1 of the hole 22X and the recess 22Y of the hub axle 22 is formed in the end cover 28, for example. The end portions of the linear members are inserted into at least 1 of the holes 22X and the recesses 22Y, so that the auxiliary member 92 is mounted to the hub axle 22. The hub axle 22 includes both a bore 22X and a recess 22Y.

As shown in fig. 20 and 21, for example, the auxiliary member 92 includes a hub axle mounting portion 92A. The hub axle mounting portion 92A is inserted into at least 1 of the hole 22X and the recess 22Y of the hub axle 22. For example, the auxiliary member 92 includes a first cable supporting portion 92B. The first cable support portion 92B is in contact with the first face 88X. For example, the auxiliary member 92 includes a second cable supporting portion 92C. The second cable support portion 92C is in contact with the second face 88Y. The hub axle mounting portion 92A, the first cable supporting portion 92B, and the second cable supporting portion 92C are integrally formed of a linear member.

For example, the assist member 92 is configured to be switchable from one of the first state and the second state to the other. In fig. 21, the auxiliary member 92 in the first state is shown with a solid line. For example, the first state is a state in which at least a part of the exposed portion 88B in the cable 88 is guided in the radial direction X2. The auxiliary member 92 guides the cable 88 in the radial direction X2 in such a manner that the exposed portion 88B is away from the center axis C1 in the first state. In fig. 21, the auxiliary member 92 in the second state is shown by a two-dot chain line. For example, the second state is to guide at least a part of the exposed portion 88B in the cable 88 in the axial direction X1. In the second state, the auxiliary member 92 guides the cable 88 inward in the radial direction X2 so that the exposed portion 88B approaches the center axis C1. The auxiliary member 92 guides the exposed portion 88B in the cable 88 in the axial direction X1 in the second state.

For example, in a state in which the hub assembly 20 is mounted to the frame 14, the auxiliary member 92 is set to the first state. For example, in a case where the sprocket 12 is attached to the sprocket support 32 and in a case where the sprocket 12 is detached from the sprocket support 32, the auxiliary member 92 is set to the second state. The switching between the first state and the second state can be achieved by, for example, the operator pressing or pulling the assist member 92.

Method of assembling hub Assembly 20

In the shaft member 26, a tool engaging portion 84 is provided on a surface 84A facing the axial direction X1 of an end portion 26C of the shaft member 26 in the axial direction X1 with respect to a center axis C1 of the shaft member 26. The surface 84A facing the axial direction X1 is, for example, an end surface of the shaft member 26. The tool engaging portion 84 can engage the tool T2.

For example, the tool engaging portion 84 includes at least 1 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 part of the tool engagement surface 84B is formed perpendicularly to the axial direction X1. For example, at least 1 recess 86 continues in the radial direction X2 from the outer surface 26B to the inner surface 26A. The recess 86 is open at least in the radial direction X2, for example. The recess 86 is open in the axial direction X1, for example.

As shown in fig. 19, for example, at least 1 recess 86 includes a first recess 86A and a second recess 86B. For example, the second concave portion 86B is disposed on the opposite side of the first concave portion 86A with respect to the center axis C1 in the circumferential direction X3 with respect to the center axis C1. The second concave portion 86B is disposed on the opposite side of the first concave portion 86A with respect to the center axis C1 in the radial direction X2, for example. The first concave portion 86A and the second concave portion 86B are disposed so as to sandwich the center axis C1. In the present embodiment, the recess 86 of the tool engaging portion 84 includes a positioning recess 82B in which the positioning member 80 is disposed as shown in fig. 7. The positioning member 80 is attached to the end cover 28X and disposed at the tool engaging portion 84. The second portion 80B of the positioning member 80 is disposed in the recess 86 of the tool engaging portion 84. The recess 86 of the tool engaging portion 84 may be provided independently of the positioning recess 82B.

The method of assembling the hub assembly 20 is described with reference to fig. 4, 5, 9 and 22. The method of assembling the hub assembly 20 includes a first process, a second process, a third process, a fourth process, a fifth process, and a sixth process.

The first step is a step of disposing the power generation section 40 and the housing regulating member 62X on the shaft member 26. In the first step, after the power generation section 40 is attached to the second shaft section 26Y of the shaft member 26, the housing restriction member 62X is attached to the power generation section 40.

The second step is a step of disposing the housing 62 on the shaft member 26. In the second step, after the housing 62 is disposed on the first shaft portion 26X of the shaft member 26 from the radial direction X2, the housing 62 is attached to the housing regulating member 62X. The lead wire 50B led out from the winding 50A is electrically connected to the housing 62. The cable 88 is connected to the connector 70 of the housing 62.

The third step is a step of disposing the hub shell 24 on the shaft member 26. The hub shell 24 having the magnet 44, the back yoke 42C and the additional bearing 30A mounted on the inner surface thereof is disposed on the shaft member 26.

The fourth step is a step of attaching an additional cap 30 to the shaft member 26. In the fourth step, the position of the additional bearing 30A disposed on the inner surface of the hub shell 24 in the axial direction X1 is located. In the fourth step, the tool T2 is engaged with the tool engaging portion 84, and rotation of the shaft member 26 in at least the circumferential direction X3 is suppressed. In a state where rotation of the shaft member 26 in the circumferential direction X3 is suppressed, the additional cap 30 is attached to the shaft member 26. The tool engagement portion 84 can suppress rotation of the shaft member 26 in the circumferential direction X3, and therefore, the additional cap 30 can be easily attached to the shaft member 26.

The fifth process is a process of mounting the torque transmitting structure 36 to the hub shell 24. In the fifth step, the tool T1 is rotated in the circumferential direction X3 in a state where the spline of the tool T1 is engaged with the tool engaging portion 36C, and the torque transmission structure 36 is attached to the hub shell 24.

The sixth step is a step of attaching the end cap 28X to the shaft member 26. In the sixth process, the cable 88 connected to the connector 70 is led out to the outside of the hub shell 24 through the hollow-shaped portion of the end cover 28X. The end cap 28X is attached to the shaft member 26 in a state where the cable 88 passes through the hollow-shaped portion of the end cap 28X.

Method for determining rotation by control unit 78

A method of determining the rotation performed by the control unit 78 will be described with reference to fig. 23 and 24.

The magnetic sensor 76 is configured 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, for example. The magnetic sensor 76 is configured to output a detection signal to the control unit 78 when the magnetic flux density input to the detection surface 76X is equal to or higher than a predetermined threshold value, for example. The magnetic sensor 76 is configured to output a non-detection signal to the control unit 78 when, for example, the magnetic flux density input to the detection surface 76X is smaller than a predetermined threshold value. The detection signal and the non-detection signal may be voltage values. One of the detection signal and the non-detection signal is a high signal, and one of the detection signal and the non-detection signal may be a low signal. The low signal may 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 the changes in the outputs from the first and second magnetic sensors 76A and 76B.

When the second member 72B rotates, the timing of detecting the magnetism of the magnet 74 by the first magnetic sensor 76A is different from the timing of detecting the magnetism of the magnet 74 by the first magnetic sensor 76A. The difference between the timing of detecting the magnetism of the magnet 74 by the first magnetic sensor 76A and the timing of detecting the magnetism of the 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 with respect to the center axis C1. In short, the difference between the timing of detecting the magnetism of the magnet 74 by the first magnetic sensor 76A and the timing of detecting the magnetism of the 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 with respect to the center axis C1 is smaller than, for example, the phase difference between the first magnet 74A and the second magnet 74B with respect to the center axis C1. The phase difference between the first magnet 74A and the second magnet 74B with respect to the center axis C1 is 180 degrees, for example.

When the second member 72B rotates, the first magnetic sensor 76A may be configured to output a detection signal for a first predetermined period. When the second member 72B rotates, the second magnetic sensor 76B may be configured to output the detection signal for a second predetermined period. For example, the first prescribed period is substantially equal to the second prescribed period. The phase difference between the first magnetic sensor 76A and the second magnetic sensor 76B with respect to the center 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.

In fig. 23, the change in the 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 the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B is shown by a two-dot chain line.

Time t11 shows a time when the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A becomes equal to or higher than a predetermined threshold value by the second member 72B rotating in the predetermined direction. At time t11, the output of the first magnetic sensor 76A changes from the non-detection signal to the detection signal. At time t11, the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B is less than the predetermined threshold value, and therefore, the output of the second magnetic sensor 76B is a non-detection signal.

Time t12 shows a time when the second member 72B is rotated in a predetermined direction, and the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B becomes equal to or higher than a predetermined threshold value. At time t12, the output of the second magnetic sensor 76B changes from the non-detection signal to the detection signal. At time t12, the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A is maintained at a predetermined threshold value or more, and therefore the output of the first magnetic sensor 76A is maintained as the detection signal.

Time t13 shows a time when the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A is less than the predetermined threshold value by the second member 72B further rotating in the predetermined direction. At time t13, the output of the first magnetic sensor 76A changes from the detection signal to the non-detection signal. At time t13, the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B is maintained at a predetermined threshold value or more, and therefore the output of the second magnetic sensor 76B is maintained as the detection signal.

Time t14 shows a time when the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B is less than the predetermined threshold value by the second member 72B further rotating in the predetermined direction. At time t14, the output of the second magnetic sensor 76B changes from the detection signal to the non-detection signal. At time t14, the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A is maintained below the predetermined threshold, and therefore the output of the first magnetic sensor 76A is maintained as a non-detection signal.

Fig. 23 shows a case where the second member 72B rotates in a predetermined direction with respect to the first member 72A, but when the second member 72B rotates in a direction opposite to the predetermined direction with respect to the first member 72A, 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 from time t14 to time t 11.

The control unit 78 is configured to determine the rotation of the second member 72B with respect to the first member 72A based on, for example, the output of the first magnetic sensor 76A when the output of the second magnetic sensor 76B is changed. When the output of the first magnetic sensor 76A and the output of the second magnetic sensor 76B change to the first mode, the control unit 78 determines that the second member 72B rotates in the predetermined direction relative to the first member 72A. When the output of the first magnetic sensor 76A and the output of the second magnetic sensor 76B change to the second mode, the control unit 78 determines that the second member 72B rotates in a direction opposite to the predetermined direction with respect to the first member 72A. The control unit 78 is configured not to determine the rotation of the second member 72B with respect to the first member 72A, for example, when the output of the first magnetic sensor 76A and the output of the second magnetic sensor 76B are different from each of the first mode and the second mode.

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, the output of the first magnetic sensor 76A is the detection signal in the case where the output of the second magnetic sensor 76B changes from the non-detection signal to the detection signal at time t 12. Thereafter, at time t14, when the output of the second magnetic sensor 76B changes from the detection signal to the non-detection signal, the output of the first magnetic sensor 76A is the non-detection signal.

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 the non-detection signal to the 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 the detection signal to the non-detection signal. In the second mode, the output of the first magnetic sensor 76A is a non-detection signal in the case where the output of the second magnetic sensor 76B changes from a non-detection signal to a detection signal at time t 14. Thereafter, at time t12, when the output of the second magnetic sensor 76B changes from the detection signal to the non-detection signal, the output of the first magnetic sensor 76A is the detection signal.

Referring to fig. 24, an example of control in which the control unit 78 determines the rotational direction of the second member 72B with respect to the first member 72A will be described. When the control unit 78 is supplied with electric power, for example, the control unit 78 starts the process of step S11. When the process of fig. 24 ends, for example, the control unit 78 restarts the process of step S11 after a predetermined period.

In step S11, the control unit 78 determines whether or not the output of the second magnetic sensor 76B changes from the non-detection signal to the detection signal. The control unit 78 ends the process when the output of the second magnetic sensor 76B does not change from the non-detection signal to the detection signal. When the output of the second magnetic sensor 76B changes from the non-detection signal to the detection signal, the control unit 78 proceeds to step S12.

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

In step S13, the control unit 78 determines whether or not the output of the second magnetic sensor 76B changes from the detection signal to the non-detection signal. When the output of the second magnetic sensor 76B has not changed from the detection signal to the non-detection signal, the control unit 78 again executes the process of step S13. When the output of the second magnetic sensor 76B changes from the detection signal to the non-detection signal, the control unit 78 proceeds to step S14.

In step S14, the control unit 78 determines whether or not the output of the first magnetic sensor 76A is a non-detection signal. When the output of the first magnetic sensor 76A is a non-detection signal, the control unit 78 proceeds to step S15. When the output of the first magnetic sensor 76A is not a non-detection signal, the control unit 78 ends the process. In step S15, the control unit 78 determines that the second member 72B rotates in the predetermined direction with respect to the first member 72A, and then ends the process. 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 with respect to the first member 72A.

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

In step S17, the control unit 78 determines whether or not the output of the first magnetic sensor 76A is a detection signal. When the output of the first magnetic sensor 76A is the detection signal, the control unit 78 proceeds to step S18. When the output of the first magnetic sensor 76A is not a detection signal, the control unit 78 ends the process. In step S18, the control unit 78 determines that the second member 72B rotates in a direction opposite to the predetermined direction with respect to the first member 72A, and then ends the process. 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 with respect to the first member 72A.

The connector pin 96A protrudes toward the housing portion 64 with respect to the end wall 62C in the axial direction X1 via the through hole 62E, for example. A part of the socket 96B may protrude outside the housing 62 through the through hole 62E. In a case where a part of the receptacle 96B protrudes outside the housing 62, the connector pin 96A is connected to the receptacle 96B on the second axial A2 side with respect to the end wall 62C without protruding from the end wall 62C toward the first axial direction A1.

The magnetic shield member 60 can also be mounted to the electrical component 58 with at least a portion of the magnetic shield member 60 located between the magnet 44 and the electrical component 58 when viewed from the axial direction X1. In the case where the magnetic shield member 60 is attached to the electric component 58, for example, the magnetic shield member 60 is provided to a portion of the electric component 58 where magnetic shielding is required.

The magnetic shield member 60 may be located between the magnet 44 and the electric component 58 in the axial direction X1, and may be disposed so as not to contact the magnet 44.

The magnetic shield member 60 may be formed separately from the back yoke 42C as long as the magnetic shield member 60 can be magnetically connected to the back yoke 42C. In the case where the magnetic shield member 60 is formed separately from the back yoke 42C, the magnetic shield member 60 may not be in contact with the back yoke 42C.

The recess 86 of the tool engagement portion 84 of the end portion 26C of the shaft member 26 may not be continuous from the outer surface 26B to the inner surface 26A in the radial direction X2 as long as the tool T2 can be engaged. The recess 86 of the tool engaging portion 84 continues from the outer surface 26B to a position between the outer surface 26B and the inner surface 26A in the radial direction X2, for example, in the radial direction X2. The recess 86 of the tool engaging portion 84 continues from the inner surface 26A to a position between the outer surface 26B and the inner surface 26A in the radial direction X2, for example, in the radial direction X2.

The positioning member 80 may be integrally formed with one of the end cover 28 and the shaft member 26.
