The coil lead wires 70B are disposed in the second through-hole 32Y of the partition portion 32D so as to extend from the first space S1 to the second space S2.

[0096] 3, the power generating device 50 includes, for example, a magnetic flux forming member 72. In this embodiment, the magnetostrictive member 58 and the yoke 52 form a closed magnetic circuit M1. The magnetic flux forming member 72 is disposed between the yoke 52 and the magnetostrictive member 58 in the second direction D2 so that the magnetic flux of the closed magnetic circuit M1 passes through the magnetic flux forming member 72. The magnetic flux forming member 72 can increase the magnetic flux density of the magnetic flux passing through the magnetostrictive member 58, and therefore the generated voltage of the power generating device 50 can be increased. The magnetic flux forming member 72 includes, for example, a magnet.

[0097] The operating member 34 is provided in the housing 32 so that the swinging motion inducing portion 34B can come into contact with at least one of the magnetostrictive member 58 and the mounting portion 64. The swinging motion inducing portion 34B is, for example, a protrusion arranged to overlap with at least one of the magnetostrictive member 58 and the mounting portion 64 when viewed from the first direction D1. In this embodiment, the swinging motion inducing portion 34B is arranged to overlap with both the magnetostrictive member 58 and the mounting portion 64 when viewed from the first direction D1. The swinging motion inducing portion 34B can come into contact with at least one of the magnetostrictive member 58 and the mounting portion 64 in the first direction D1, for example. The swinging motion inducing portion 34B can come into contact with at least one of the predetermined end portions of the magnetostrictive member 58 and the mounting portion 64, for example. The predetermined end portion is, for example, an end portion in the third direction D3 of at least one of the magnetostrictive member 58 and the mounting portion 64, and is an end portion opposite to the support portion 52Y. The fluctuation inducing portion 34B of the present embodiment is capable of coming into contact with the second magnetostrictive surface 58Y of the magnetostrictive member 58 in the first direction D1.

[0098] For example, when the operating section 34A of the operating member 34 is operated, the swing motion inducing section 34B is configured to induce swing motion of at least one of the magnetostrictive member 58 and the mounting section 64 of the power generating device 50. For example, the swing motion inducing section 34B presses at least one of the magnetostrictive member 58 and the mounting section 64 in association with the movement of the operating member 34. At least one of the magnetostrictive member 58 and the mounting section 64 is pushed by the swing motion inducing section 34B, whereby at least one of the magnetostrictive member 58 and the mounting section 64 moves in the first direction D1. When at least one of the magnetostrictive member 58 and the mounting section 64 moves in the first direction D1, at least one of the magnetostrictive member 58 and the mounting section 64 moves with the support section 52Y as a fulcrum.

[0099] When the user releases the operating unit 34A, the elastic member 36 biases the operating member 34, causing the operating member 34 to return to its original position. As the swing inducing portion 34B moves in the first direction D1 due to the return of the position of the operating unit 34A, at least one of the magnetostrictive member 58 and the mounting portion 64 also moves in the first direction D1. When the user presses the operating unit 34A and releases the operating unit 34A, the magnetostrictive member 58 swings. When the magnetostrictive member 58 swings, the magnetostrictive member 58 expands and contracts, changing the magnetic flux passing through the coil 70, causing the coil 70 to generate electricity.

[0122] In the example of Fig. 9, the second adhesive portion 78 includes a second adhesive portion 78 in contact with the first magnetostrictive chamfered portion 82A and the first mounting chamfered portion 86A, and a second adhesive portion 78 in contact with the second magnetostrictive chamfered portion 82B and the second mounting chamfered portion 86B.

[0123] The first end 76B has a thickness X1 in the mounting direction AD. The first central portion 76A has a thickness X2 in the mounting direction AD.

The thickness X1 may be the same as or different from the thickness X2.

[0124] The second end 76C has a thickness X3 in the mounting direction AD. The thickness X3 may be the same as the thickness X1 or may be different from the thickness X1.

The thickness X3 may be the same as the thickness X2 or may be different from the thickness X2.

[0125] 11, the maximum thickness Y2 of the second adhesive portion 78 in the mounting direction AD is greater than the maximum thickness Y1 of the first adhesive portion 76. The maximum thickness Y2 of the second adhesive portion 78 is, for example, the thickness of the end portion of the second adhesive portion 78 opposite the first adhesive portion 76 in the mounting direction AD. When the mounting side surface 64Z is configured to be substantially flush with the magnetostrictive side surface 58Z, the maximum thickness Y2 of the second adhesive portion 78 is, for example, the thickness of the second adhesive portion 78 at a portion overlapping the mounting side surface 64Z and the magnetostrictive side surface 58Z in the mounting direction AD.

[0126] The ratio of the maximum thickness Y2 of the second adhesive portion 78 in the mounting direction AD to the maximum thickness Y1 of the first adhesive portion 76 in the mounting direction AD is, for example, 1.5 or more and 5.0 or less. The ratio of the maximum thickness Y2 of the second adhesive portion 78 in the mounting direction AD to the maximum thickness Y1 of the first adhesive portion 76 in the mounting direction AD is, for example, 2.0 or more and 3.0 or less. The ratio of the maximum thickness Y2 of the second adhesive portion 78 in the mounting direction AD to the maximum thickness Y1 of the first adhesive portion 76 in the mounting direction AD is, for example, 2.2 or more and 2.8 or less. The chamfering amount of the portion of the chamfered portion 80 facing the adhesive member 74 is determined, for example, so that the ratio of the maximum thickness Y2 to the maximum thickness Y1 is 1.5 or more and 5.0. The chamfering amount of the portion of the chamfered portion 80 facing the adhesive member 74 is determined, for example, so that the ratio of the maximum thickness Y2 to the maximum thickness Y1 is 2.0 or more and 3.0. The amount of chamfering of the portion of the chamfered portion 80 facing the adhesive member 74 is determined so that the ratio of the maximum thickness Y2 to the maximum thickness Y1 is, for example, 2.2 or more and 2.8 or less.

[0127] When manufacturing the magnetostrictive member 58 and the mounting portion 64, convex portions may be generated at the corners. The convex portions include, for example, burrs generated during manufacturing. If the magnetostrictive member 58 and the mounting portion 64 have convex portions, when the magnetostrictive member 58 is attached to the mounting portion 64 by the adhesive member 74, the thickness of the adhesive member 74 increases due to the convex portions. In the power generating device 50 of this embodiment, the chamfered portion 80 is provided at a portion facing the adhesive member 74, so that the magnetostrictive member 58 and the mounting portion 64 are chamfered to remove convex portions such as burrs. Since the convex portions such as burrs are removed, the magnetostrictive member 58 and the mounting portion 64 are less likely to have convex portions. Therefore, the thickness from the second magnetostrictive surface 58Y of the magnetostrictive member 58 to the second mounting surface 64Y of the mounting portion 64 in the mounting direction AD can be reduced. Therefore, the power generating device 50 is prevented from becoming large.

[0128] If the magnetostrictive member 58 and the mounting portion 64 have protrusions, it is difficult to make the thickness of the adhesive member 74 uniform. If the thickness of the adhesive is non-uniform, when the magnetostrictive member 58 oscillates, the power generated by the oscillation of the magnetostrictive member 58 becomes unstable. In the power generating device 50 of this embodiment, the chamfered portion 80 is provided in a portion facing the adhesive member 74, so that the magnetostrictive member 58 and the mounting portion 64 are unlikely to have protrusions. Therefore, it is easy to make the thickness of the adhesive member 74 uniform.

[0129] If the magnetostrictive member 58 and the mounting portion 64 have a convex portion, when the magnetostrictive member 58 and the mounting portion 64 move toward the coil 70, the convex portion may come into contact with the coil inner surface 70A, and the convex portion may apply pressure to the coil inner surface 70A. The magnetostrictive member 58 and the mounting portion 64 may move toward the coil 70, for example, when the magnetostrictive member 58 and the mounting portion 64 are disposed in the internal space 70S of the coil 70 during the manufacture of the power generating device 50, when the magnetostrictive member 58 is swung by the operating member 34, and when vibration is applied to the power generating device 50 due to the running of the human-powered vehicle 10, etc. In the power generating device 50 of this embodiment, the chamfered portion 80 is provided in a portion facing the coil inner surface 70A, so that the magnetostrictive member 58 and the mounting portion 64 are unlikely to have a convex portion. Therefore, deformation of the coil 70 can be suppressed, and therefore a decrease in power generation efficiency due to deformation of the coil 70 can be suppressed.

[0130] <Example of change> The description of the embodiments is an example of possible forms of the power generation device and the electrical components for a human-powered vehicle according to the present disclosure, and is not intended to limit the forms. The power generation device and the electrical components for a human-powered vehicle according to the present disclosure may take the following modified examples of the embodiments, or a combination of at least two mutually non-conflicting modified examples. In the following modified examples, parts common to the embodiments are given the same reference numerals as the embodiments, and descriptions thereof are omitted.

[0131] The shape of the housing 32 may be changed as appropriate. The housing 32 may have any shape as long as it can accommodate at least a portion of the power generation device 50. The components of the housing 32 may extend in any direction.

[0132] The mounting direction AD may be a direction different from the first direction D1. The mounting direction AD in this modified example may be any direction as long as the coil 70 can generate power by the oscillation of the magnetostrictive member 58 in the first direction D1. In this modified example, the mounting direction AD may be at least one of the second direction D2 and the third direction D3.

[0133] The magnetostrictive member 58 may be attached to the mounting portion 64 by a rod-shaped member instead of or in addition to the adhesive member 74. The rod-shaped member includes, for example, a pin and a bolt. The rod-shaped member may be made of, for example, metal, resin, etc. Even when the magnetostrictive member 58 is attached to the mounting portion 64 by a rod-shaped member, the chamfered portion 80 makes it easy for the magnetostrictive member 58 and the mounting portion 64 to come into close contact with each other. Therefore, the chamfered portion 80 has the effect of preventing the power generation device 50 from becoming larger.

[0134] The power generating device 50 may have, instead of or in addition to the adhesive member 74, a convex portion provided on one of the magnetostrictive member 58 and the mounting portion 64, and a concave portion provided on the other of the magnetostrictive member 58 and the mounting portion 64. The magnetostrictive member 58 may be attached to the mounting portion 64 by inserting the convex portion provided on one of the magnetostrictive member 58 and the mounting portion 64 into the concave portion provided on the other of the magnetostrictive member 58 and the mounting portion 64.

[0135] The magnetostrictive member 58 may be formed integrally with the mounting portion 64. When the magnetostrictive member 58 is formed integrally with the mounting portion 64, the adhesive member 74 may be omitted. For example, the magnetostrictive member 58 is formed integrally with the mounting portion 64 by welding, pressing, or the like. When the magnetostrictive member 58 is formed integrally with the mounting portion 64, a chamfered portion may be provided on at least one of the magnetostrictive member 58 and the mounting portion 64 by chamfering each edge of the assembled body of the magnetostrictive member 58 and the mounting portion 64 that are integrally formed. When the magnetostrictive member 58 is formed integrally with the mounting portion 64, at least one of the magnetostrictive member 58 and the mounting portion 64 may be chamfered before the magnetostrictive member 58 is formed integrally with the mounting portion 64. When the magnetostrictive member 58 is formed integrally with the mounting portion 64 by welding, or the like, a burr removal process may be performed on the portions of the magnetostrictive member 58 and the mounting portion 64 where burrs are generated by welding, or the like.

[0136] The mounting portion 64 may have a different shape from the magnetostrictive member 58 when viewed from the first direction D1. In this modification, the first mounting surface 64X of the mounting portion 64 may have a predetermined portion that does not overlap with the magnetostrictive member 58 in the first direction D1. A chamfered portion 80 may be provided at the predetermined portion of the first mounting surface 64X. The predetermined portion may be an end portion of the extension portion 56C in at least one of the second direction D2 and the third direction D3. The predetermined portion may be an end portion of the support portion 52Y in at least one of the second direction D2 and the third direction D3. The predetermined portion may be provided midway through the mounting portion 64 in the second direction D2.

[0137] The chamfered portion 80 is provided on the portion of the magnetostrictive member 58 facing the adhesive member 74, and does not have to be provided on the portion of the mounting portion 64 facing the adhesive member 74. In this modified example, if the chamfered portion 80 includes the first magnetostrictive chamfered portion 82, at least the first magnetostrictive outer edge 60 and the vicinity of the first magnetostrictive outer edge 60 are unlikely to have a convex portion. Therefore, in this modified example, the thickness from the second magnetostrictive surface 58Y of the magnetostrictive member 58 to the second mounting surface 64Y of the mounting portion 64 can be reduced. In this modified example, it is also possible to prevent the thickness of the adhesive member 74 from becoming uneven.

[0138] The chamfered portion 80 is provided on the portion of the mounting portion 64 facing the adhesive member 74, and does not have to be provided on the portion of the magnetostrictive member 58 facing the adhesive member 74. In this modified example, if the chamfered portion 80 includes the first mounting chamfered portion 86, at least the first mounting outer edge 66 and the vicinity of the first mounting outer edge 66 are unlikely to have a convex portion. Therefore, in this modified example, the thickness from the second magnetostrictive surface 58Y of the magnetostrictive member 58 to the second mounting surface 64Y of the mounting portion 64 can be reduced. In this modified example, it is also possible to prevent the thickness of the adhesive member 74 from becoming uneven.

[0139] The power generating device 50 may omit other components as long as it includes the magnetostrictive member 58 including the chamfered portion 80 facing the coil inner surface 70A. For example, the power generating device 50 includes the magnetostrictive member 58 formed to include a magnetostrictive material and capable of swinging in the first direction D1, and the coil 70 that generates power by swinging the magnetostrictive member 58 in the first direction D1, the coil 70 includes the coil inner surface 70A facing the magnetostrictive member 58, and the magnetostrictive member 58 includes the chamfered portion 80 provided to face the coil inner surface 70A, so that other components can be omitted. In this modification, for example, the chamfered portion 80 may not be provided in the portion of the magnetostrictive member 58 facing the adhesive member 74. In this modification, for example, the chamfered portion 80 may not be provided in the mounting portion 64.

[0140] The second magnetostrictive chamfered portion 84 may be provided so as to be continuous only with the portion of the second magnetostrictive outer edge 62 that faces the coil inner surface 70A. Also, the second mounting chamfered portion 88 may be provided so as to be continuous only with the portion of the second mounting outer edge 68 that faces the coil inner surface 70A.

[0141] The first magnetostrictive chamfer 82 may be provided discontinuously along the first magnetostrictive outer edge 60, provided that the first magnetostrictive chamfer 82 is continuous with the first magnetostrictive outer edge 60. At least one of the second magnetostrictive chamfer 84, the first mounting chamfer 86, and the second mounting chamfer 88 may also be provided discontinuously, similar to the first magnetostrictive chamfer 82.

When the electrical component 30 includes at least one of the sensor 28X and the power meter 28Y, the operating device 38 may include at least one of the sensor 28X and the power meter 28Y. When the electrical component 30 includes at least one of the gear shifter 26A, the adjustable seat post 26B, the suspension 26C, the drive unit 26D, and the braking device 26E, the operating device 38 may include an actuator included in at least one of the gear shifter 26A, the adjustable seat post 26B, the suspension 26C, the drive unit 26D, and the braking device 26E. In the case where electrical component 30 includes lamp 26F, operating device 38 may include the light source of lamp 26F. The sensor 28X is configured to detect at least one of the rotation speed of the crankshaft 22B, the human-powered driving force, the force applied to the handlebars 20 of the human-powered vehicle 10, and the pedal angle, for example.

The inclination of the rider's upper body relative to the frame 12 of the human-powered vehicle 10 is, for example, the inclination of the rider's upper body relative to the front-rear direction of the human-powered vehicle 10. The greater the inclination, the more the rider leans forward. The greater the angle of the rider's ankles, the further the toes are away from the knees. The sensor 28X includes, for example, a magnetic sensor, an optical sensor, an acceleration sensor, a gyro sensor, a torque sensor, a vehicle speed sensor, an inclination sensor, a strain sensor, a magnetostrictive sensor, a pressure sensor, and the like. The strain sensor includes a strain gauge. The sensor 28X may include a camera provided at a location capable of photographing the lidar. The power meter 28Y is disposed, for example, on a transmission path of the human-powered driving force.

[0143] The electric component 30 does not have to include the operating device 38. The electric component 30 may be configured to output the generated electric power to an operating device 38 provided separately from the electric component 30 or to a power storage unit.
