The magnetic shielding member 60 overlaps all the magnets 44 when viewed from the axial direction X1. Therefore, the magnetic shield member 60 includes a region overlapping all the magnets 44 when viewed from the axial direction X1. The magnetic shielding member 60 is arranged at the same position as the restricting member 52 in the axial direction X1. For example, the magnetic shielding member 60 contains a soft magnetic material.

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 direction X2. The first radial distance Y1 is, for example, the distance from the central axis C1 to the end of the magnetic shield member 60 located innermost in the radial direction X2. For example, the second radial distance Y2 is the distance from the central axis C1 to the magnet 44 in the radial direction X2.

For example, the magnetic shield member 60 is disposed in contact with the rear yoke 42C. For example, the magnetic shield member 60 is integrated with the rear yoke 42C. For example, the magnetic shielding member 60 is arranged over the entire circumference in the circumferential direction X3 with respect to the central axis C1. The magnetic shield member 60 is arranged so that the first radial distance Y1 is substantially the same over the entire circumference. For example, with respect to the magnetic shielding member 60 , even when the magnet 44 rotates around the central axis C1 , the magnetic shielding member 60 is arranged over the entire circumference, so the magnetic shielding member 60 can change the traveling direction of the magnetic field lines of the magnet 44 . The magnetic shield member 60 is formed, for example, by bending the end portion of the rear yoke 42C radially inward. For example, the magnetic shielding member 60 is disposed in contact with the magnet 44 .

如圖8所示，殼體限制構件62X，用來限制殼體62相對於軸構件26的移動。殼體限制構件62X例如藉由螺絲等安裝於殼體62。殼體限制構件62X例如包含與軸方向X1垂直地延伸的板狀構件。殼體限制構件62X，例如在與殼體62的安裝部分不同的部分，藉由以螺絲等安裝於發電部40，來安裝於軸構件26且不相對於軸構件26移動。殼體限制構件62X例如安裝於第1限制構件52C。As shown in FIG. 8 , the housing restricting member 62X is used to restrict the movement of the housing 62 relative to the shaft member 26 . The housing restricting member 62X is attached to the housing 62 by, for example, screws. The case restricting member 62X includes, for example, a plate-shaped member extending perpendicularly to the axial direction X1. The case restricting member 62X is attached to the shaft member 26 by being attached to the power generation unit 40 with screws or the like at a portion different from the attachment portion of the case 62 so as not to move relative to the shaft member 26 . The housing restriction member 62X is attached to the first restriction member 52C, for example.

如圖4所示，殼體62將軸構件26的至少局部包圍。例如軸構件26包含第1軸部26X。例如第1軸部26X在相對於中心軸心C1的軸方向X1配置有殼體62。第1軸部26X的尺寸D1，例如在第1軸部26X，是在與軸方向X1垂直的方向的軸構件26的外面部26B的外徑之中最大的尺寸。As shown in FIG. 4 , the housing 62 surrounds at least part of the shaft member 26 . For example, the shaft member 26 includes the first shaft portion 26X. For example, the housing 62 is arranged in the first shaft portion 26X in the axial direction X1 with respect to the central axis C1. The dimension D1 of the first shaft portion 26X is, for example, the largest dimension among the outer diameters of the outer portion 26B of the shaft member 26 in the direction perpendicular to the axial direction X1.

例如軸構件26包含第1軸部26X及第2軸部26Y。例如第2軸部26Y，在軸方向X1與第1軸部26X不同。第2軸部26Y，相對於第1軸部26X配置在第2軸方向A2側。例如徑向X2上的第2軸部26Y的尺寸D2，大於徑向X2上的第1軸部26X的尺寸D1。例如在第2軸部26Y設置有發電部40。在殼體62配置於軸構件26的狀態，第2軸部26Y的尺寸D2是在軸方向X1讓殼體62無法移動超過第2軸部26Y的尺寸。於是殼體62，在軸方向X1，無法從第2軸部26Y朝向第1軸部26X***於軸構件26。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 arranged on the second axis direction 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 power generation unit 40 is provided in the second shaft portion 26Y. When the housing 62 is arranged on the shaft member 26, the dimension D2 of the second shaft portion 26Y is a size that prevents the housing 62 from moving 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.

例如軸構件26包含第3軸部26Z。例如第3軸部26Z，在軸方向X1與第1軸部26X及第2軸部26Y的雙方不同。第3軸部26Z，相對於第1軸部26X配置在第1軸方向A1側。例如第2軸部26Y及第3軸部26Z配置成隔著第1軸部26X。例如徑向X2上的第3軸部26Z的尺寸D3，大於徑向X2上的第1軸部26X的尺寸D1。例如在第3軸部26Z安裝有軸承34。在殼體62配置於軸構件26的狀態，第3軸部26Z的尺寸D3是在軸方向X1讓殼體62無法移動超過第3軸部26Z的尺寸。於是殼體62，在軸方向X1，無法從第3軸部26Z朝向第1軸部26X***於軸構件26。For example, the shaft member 26 includes the 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 arranged on the first axis 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, the bearing 34 is attached to the third shaft portion 26Z. When the housing 62 is arranged on the shaft member 26, the dimension D3 of the third shaft portion 26Z is a size that prevents the housing 62 from moving 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.

軸構件接收部66用來接收軸構件26。藉由讓軸構件26經由開口部68而從徑向X2接收於軸構件接收部66，來將殼體62配置於軸構件26。軸構件接收部66配置於內壁62A的徑向內面部。例如軸構件接收部66，在相對於中心軸心C1的周方向X3，沿著軸構件26的至少局部的形狀。例如在軸構件接收部66作成沿著軸構件26的外周面之中圓弧形狀的部分的形狀的情況，則軸構件接收部66具有與軸構件26的外周面的圓弧形狀對應的形狀。例如軸構件接收部66作成，在周方向X3沿著軸構件26的90度以上200度以下的部分的形狀。換言之，軸構件接收部66之中沿著軸構件26的形狀的部分，具備有與在周方向X3上90度以上200度以下對應的長度。例如軸構件接收部66作成，在周方向X3沿著軸構件26的實質180度的部分的形狀。Shaft member receiving portion 66 is used to receive shaft member 26 .

The shaft member receiving portion 66 is arranged on the radial inner surface of the inner wall 62A. For example, the shaft member receiving portion 66 follows at least a partial shape of the shaft member 26 in the circumferential direction X3 relative to the central axis C1. For example, when the shaft member receiving portion 66 is shaped along an arc-shaped portion of the outer peripheral surface of the shaft member 26 , the shaft member receiving portion 66 has a shape corresponding to the arc shape of the outer peripheral surface of the shaft member 26 . For example, the shaft member receiving portion 66 has a shape along a portion of the shaft member 26 extending from 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 or more and 200 degrees or less in the circumferential direction X3. For example, the shaft member receiving portion 66 has a shape along a substantially 180-degree portion of the shaft member 26 in the circumferential direction X3.

The opening 68 is connected to the shaft member receiving portion 66 in the radial direction X2 with respect to the central axis C1. For example, the opening 68 is arranged in a different portion from the portion of the shaft member receiving portion 66 along the shaft member 26 in the circumferential direction X3, and is formed from an end portion of the housing 62 in the axial direction One party covers the other. The opening 68 covers from the inner wall 62A to the outer wall 62B in the radial direction X2.

On the radially inner surface of the inner wall 62A, the shaft member receiving portion 66 is arranged adjacent to the first side portion 68A, and the second side portion 68B is arranged adjacent to the shaft member receiving portion 66 . In the circumferential direction X3, the first side portion 68A is arranged at one end of the shaft member receiving portion 66, and the second side portion 68B is arranged 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.

例如開口部68形成了可讓軸構件26通過的軸構件通過路線68C。軸構件通過路線68C，是從殼體62的外壁62B起至內壁62A的連續通路。例如軸構件26經由軸構件通過路線68C而接收於軸構件接收部66。軸構件26通過軸構件通過路線68C而接收於軸構件接收部66。例如開口部68的開口尺寸D4，為徑向X2上的第1軸部26X的尺寸D1以上。開口部68的開口尺寸D4，例如從軸方向X1觀察，為從第1側部68A起至第2側部68B的距離。例如開口部68的開口尺寸D4，大於徑向X2上的第1軸部26X的尺寸D1。在本實施方式，由於第1側部68A及第2側部68配置成平行，所以經過軸構件通過路線68C的開口尺寸D4為一定的。而只要能讓軸構件26通過軸構件通過路線68C，開口部68的開口尺寸D4，通過軸構件通過路線68C也可部分改變。For example, the opening 68 forms a shaft member passage path 68C through which the shaft member 26 can pass. The shaft member passing route 68C is a continuous passage from the outer wall 62B of the housing 62 to the inner wall 62A. For example, the shaft member 26 is received in the shaft member receiving portion 66 via the shaft member passage path 68C. Shaft member 26 is received in shaft member receiver 66 via shaft member passage path 68C. For example, the opening size D4 of the opening 68 is equal to or larger than the size D1 of the first shaft portion 26X in the radial direction X2. The opening size D4 of the opening 68 is, for example, the distance from the first side 68A to the second side 68B when viewed from the axial direction X1. For example, the opening size D4 of the opening 68 is larger than the size D1 of the first shaft portion 26X in the radial direction X2. In the present embodiment, since the first side portion 68A and the second side portion 68 are arranged in parallel, the opening size D4 passing through the shaft member passage path 68C is constant. As long as the shaft member 26 can pass through the shaft member passage route 68C, the opening size D4 of the opening 68 can be partially changed through the shaft member passage route 68C.

Therefore, when the first member 72A does not rotate, the magnetism generating component 72X does not rotate. On the other hand, when the first member 72A rotates, the magnetism generating component 72X rotates integrally with the first member 72A. The magnetic generating component 72X is mounted on the electrical substrate 58A so as not to rotate relative to the first member 72A.

The magnetic component 74X is a magnet 74, for example. Magnetic sensor 76 is provided on electrical substrate 58A. The magnetic sensor 76 is arranged closer to the electric component 58 than the magnetic shield member 60 in the axial direction X1. The magnetic sensor 76 does not rotate relative to the first member 72A, and is used to detect the magnetism of the magnet 74 . 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 does not rotate relative to the first member 72A, and is used to detect the magnetism of at least one magnet 74 . At least one magnetic sensor 76 cannot rotate relative to the first member 72A. The magnetic sensor 76 is mounted on the electrical substrate 58A so as to prevent relative rotation with the first member 72A. The magnetic sensor 76 is a different entity from the first member 72A, for example. The magnetic sensor 76 is, for example, provided on the first member 72A and can rotate integrally with the first member 72A. For example, at least one magnetic sensor 76 is configured not to face the at least one magnet 74 . The magnetic sensor 76 is arranged so as not to face the magnet 74 in the axial direction X1. For example, at least one magnetic sensor 76 is arranged in the first region R1 in the radial direction X2.

A magnetic detection element is arranged on the detection surface 76X. The detection surface 76X is arranged non-perpendicularly to the magnetization direction M1 in which the S pole and the N pole of at least one magnet 74 are arranged. For example, the magnetization direction M1 is parallel to the axial direction X1. The detection surface 76X is arranged to be inclined with respect to the magnetization direction M1 or parallel to the magnetization direction M1. For example, the detection surface 76X is arranged parallel to the magnetization direction M1.

從磁鐵74產生的磁性的磁通密度，隨著朝向與磁化方向M1交叉的方向且朝向遠離磁鐵74的方向而變低。而且磁鐵74的磁力線的行進方向，隨著遠離磁鐵74而朝與磁化方向M1交叉的方向彎曲。藉由將磁性感應器76配置在從磁鐵74朝軸方向X1偏移且從磁鐵74朝徑向X2偏移的位置，讓磁性感應器76能高效率地檢測磁鐵74的磁性。The magnetic flux density of the magnet 74 becomes lower in a direction intersecting the magnetization direction M1 and in a direction away from the magnet 74 . Furthermore, the traveling direction of the magnetic field lines of the magnet 74 curves in a direction intersecting the magnetization direction M1 as it moves away from the magnet 74 . By arranging the magnetic sensor 76 at a position offset from the magnet 74 in the axial direction X1 and offset from the magnet 74 in the radial direction X2, the magnetic sensor 76 can efficiently detect the magnetism of the magnet 74 .

＜控制部78的旋轉判斷方法＞ 參考圖23及圖24，來說明控制部78的旋轉判斷方法。 磁性感應器76，例如在檢測到磁性的情況，對控制部78輸出檢測訊號，在未檢測到磁性的情況，對控制部78輸出非檢測訊號。磁性感應器76，例如在對檢測面76X輸入的磁通密度為預定臨界值以上的情況，則對控制部78輸出檢測訊號。磁性感應器76，例如在對檢測面76X輸入的磁通密度小於預定臨界值的情況，則對控制部78輸出非檢測訊號。檢測訊號及非檢測訊號也可是電壓值。檢測訊號及非檢測訊號的其中一方是高訊號，檢測訊號及非檢測訊號的其中一方是低訊號也可以。低訊號也可是0V。控制部78，因應來自第1磁性感應器76A及第2磁性感應器76B的輸出的變化，來判斷第2構件72B相對於第1構件72A的旋轉。 <Rotation determination method of control unit 78> The rotation determination method of the control unit 78 will be described with reference to FIGS. 23 and 24 . For example, the magnetic sensor 76 outputs a detection signal to the control unit 78 when magnetism is detected, and outputs a non-detection signal to the control unit 78 when magnetism is not detected. For example, when the magnetic flux density input to the detection surface 76X is equal to or higher than a predetermined threshold value, the magnetic sensor 76 outputs a detection signal to the control unit 78 . For example, when the magnetic flux density input to the detection surface 76X is less than a predetermined threshold value, the magnetic sensor 76 outputs a non-detection signal to the control unit 78 . The detection signal and the non-detection signal can also be voltage values. One of the detection signal and the non-detection signal may be a high signal, or one of the detection signal and the non-detection signal may be a low signal. Low signal can also be 0V. The control unit 78 determines the rotation of the second member 72B relative to the first member 72A in response to changes in the outputs from the first magnetic sensor 76A and the second magnetic sensor 76B.

在第2構件72B旋轉的情況，第1磁性感應器76A對磁鐵74的磁性的檢測時機、與第2磁性感應器76B對磁鐵74的磁性的檢測時機不同。第1磁性感應器76A對磁鐵74的磁性的檢測時機、與第2磁性感應器76B對磁鐵74的磁性的檢測時機的差，對應於相對於中心軸心C1的第1磁性感應器76A與第2磁性感應器76B的相位差。也就是說，第1磁性感應器76A對磁鐵74的磁性的檢測時機、與第2磁性感應器76B對磁鐵74的磁性的檢測時機的差，對應於第1磁性感應器76A與第2磁性感應器76B在周方向X3的位置。相對於中心軸心C1的第1磁性感應器76A與第2磁性感應器76B的相位差，例如小於相對於中心軸心C1的第1磁鐵74A與第2磁鐵74B的相位差。相對於中心軸心C1的第1磁鐵74A與第2磁鐵74B的相位差例如是180度。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 second magnetic sensor 76B. 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 difference between the first magnetic sensor 76A and the second magnetic sensor 76A with respect to the central axis C1. 2 Phase difference of magnetic sensor 76B. In other words, 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 difference between the first magnetic sensor 76A and the second magnetic sensor. The device 76B is at a position in the circumferential direction X3. The phase difference between the first magnetic sensor 76A and the second magnetic sensor 76B with respect to the central axis C1 is, for example, smaller than the phase difference between the first magnet 74A and the second magnet 74B with respect to the central axis C1. The phase difference between the first magnet 74A and the second magnet 74B with respect to the central axis C1 is, for example, 180 degrees.

也可作成在第2構件72B旋轉的情況，第1磁性感應器76A在第1預定期間內輸出檢測訊號。也可作成在第2構件72B旋轉的情況，第2磁性感應器76B在第2預定期間內輸出檢測訊號。例如第1預定期間實質與第2預定期間相等。相對於中心軸心C1的第1磁性感應器76A與第2磁性感應器76B的相位差，例如設定成：在第1磁性感應器76A輸出檢測訊號的情況，第2磁性感應器76B的輸出從非檢測訊號變成檢測訊號。When the second member 72B rotates, the first magnetic sensor 76A may output a detection signal within the first predetermined period. When the second member 72B rotates, the second magnetic sensor 76B may output a detection signal within the 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, for example, set so that when the first magnetic sensor 76A outputs a detection signal, the output of the second magnetic sensor 76B is from The non-detection signal becomes a detection signal.

在圖23，以實線顯示對第1磁性感應器76A的檢測面76X輸入的磁通密度的變化，以兩點鏈線顯示對第2磁性感應器76B的檢測面76X輸入的磁通密度的變化。In FIG. 23 , the change of the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A is shown as a solid line, and the change of the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B is shown as a two-dot chain line. change.

At time t11, the output of the first magnetic sensor 76A changes from a non-detection signal to a detection signal. At time t11, since the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B is less than the predetermined threshold value, the output of the second magnetic sensor 76B is a non-detection signal.

At time t12, the output of the second magnetic sensor 76B changes from a non-detection signal to a detection signal. At time t12, since the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A is maintained above the predetermined threshold value, the output of the first magnetic sensor 76A is maintained as a detection signal.

At time t13, the output of the first magnetic sensor 76A changes from a detection signal to a non-detection signal. At time t13, since the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B is maintained above the predetermined threshold value, the output of the second magnetic sensor 76B is maintained as a detection signal.

時刻t14，是顯示藉由第2構件72B進一步朝預定方向旋轉，而對第2磁性感應器76B的檢測面76X輸入的磁通密度變成小於預定臨界值的時刻。在時刻t14，第2磁性感應器76B的輸出從檢測訊號變化成非檢測訊號。在時刻t14，由於對第1磁性感應器76A的檢測面76X輸入的磁通密度維持為小於預定臨界值，所以第1磁性感應器76A的輸出維持為非檢測訊號。Time t14 indicates a time when the magnetic flux density input to the detection surface 76X of the second magnetic sensor 76B becomes less than a predetermined threshold value as the second member 72B further rotates 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, since the magnetic flux density input to the detection surface 76X of the first magnetic sensor 76A remains smaller than the predetermined threshold value, the output of the first magnetic sensor 76A remains a non-detection signal.

圖23雖然顯示了第2構件72B相對於第1構件72A朝預定方向旋轉的情況，而在第2構件72B相對於第1構件72A朝預定方向的相反方向旋轉的情況，會如從時刻t14朝向時刻t11，對第1磁性感應器76A的檢測面76X輸入的磁通密度、對第2磁性感應器76B的檢測面76X輸入的磁通密度、第1磁性感應器76A的輸出、及第2磁性感應器76B的輸出產生變化。FIG. 23 shows the case where the second member 72B rotates in the predetermined direction relative to the first member 72A. However, in the case where the second member 72B rotates in the opposite direction to the predetermined direction relative to the first member 72A, as shown in FIG. 23 , from time t14 toward At time t11, 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 second magnetic The output of sensor 76B changes.

控制部78，例如因應於第2磁性感應器76B的輸出變化的情況的第1磁性感應器76A的輸出，來判斷第2構件72B相對於第1構件72A的旋轉。控制部78，在第1磁性感應器76A及第2磁性感應器76B的輸出變化為第1模式的情況，則判斷第2構件72B相對於第1構件72A是朝預定方向旋轉。控制部78，在第1磁性感應器76A及第2磁性感應器76B的輸出變化為第2模式的情況，則判斷第2構件72B相對於第1構件72A是朝預定方向的相反方向旋轉。控制部78，例如在第1磁性感應器76A及第2磁性感應器76B的輸出變化與第1模式及第2模式的任一種都不相同的情況，則不判斷第2構件72B相對於第1構件72A的旋轉。The control unit 78 determines the rotation of the second member 72B relative to the first member 72A in response to, for example, the output of the first magnetic sensor 76A when the output of the second magnetic sensor 76B changes. When the outputs of the first magnetic sensor 76A and the second magnetic sensor 76B change to the first mode, the control unit 78 determines that the second member 72B rotates in a predetermined direction relative to the first member 72A. When the outputs of the first magnetic sensor 76A and the second magnetic sensor 76B change to the second mode, the control unit 78 determines that the second member 72B rotates in the opposite direction to the predetermined direction relative to the first member 72A. For example, when the output changes of the first magnetic sensor 76A and the second magnetic sensor 76B are different from those of the first mode and the second mode, the control unit 78 does not determine whether the second member 72B is different from the first mode. Rotation of member 72A.

In the second mode, when the output of the second magnetic sensor 76B changes from a non-detection signal to a detection signal at time t14, the output of the first magnetic sensor 76A becomes a non-detection signal. Then, when the output of the second magnetic sensor 76B changes from the detection signal to the non-detection signal at time t12, the output of the first magnetic sensor 76A becomes the detection signal.
