　（１）実施形態１
　（１．１）実施形態１の概要
　図１は、本実施形態に係る電動自転車１の側面図である。電動自転車１は、フレーム２を有する。フレーム２には、モータユニット５が取り付けられる。モータユニット５は、少なくとも、バッテリ装置６と、駆動ユニット５０と、を備える。 (1) Embodiment 1
(1.1) Overview of Embodiment 1 FIG. 1 is a side view of an electric bicycle 1 according to the present embodiment. The electric bicycle 1 has a frame 2. A motor unit 5 is attached to the frame 2. The motor unit 5 includes at least a battery device 6 and a drive unit 50.
　バッテリ装置６は、駆動ユニット５０に電力を供給する装置である。バッテリ装置６は、本実施形態では、バッテリ６８と、バッテリ装着部６１（図２参照）と、移動規制部６６１（図６Ａ参照）とを備える。 The battery device 6 is a device that supplies power to the drive unit 50. In this embodiment, the battery device 6 includes a battery 68, a battery mounting portion 61 (see FIG. 2), and a movement restricting portion 661 (see FIG. 6A).
　バッテリ装着部６１には、バッテリ６８を装着し得る。バッテリ装着部６１に装着されたバッテリ６８は、取外し方向Ｄ３に沿って、バッテリ装着部６１から取り外すことができる。ここで、取外し方向Ｄ３とは、バッテリ６８がバッテリ装着部６１に装着された装着位置から、バッテリ６８がバッテリ装着部６１から外れた離脱位置に向かう方向を意味する。また、「取外し方向Ｄ３」とは反対方向を「取付け方向」とする。 The battery 68 can be attached to the battery attachment portion 61. The battery 68 attached to the battery attachment portion 61 can be removed from the battery attachment portion 61 along the removal direction D3. Here, the removal direction D <b> 3 means a direction from the attachment position where the battery 68 is attached to the battery attachment portion 61 to the separation position where the battery 68 is detached from the battery attachment portion 61. Further, the direction opposite to the “removal direction D3” is defined as the “attachment direction”.
　移動規制部６６１は、装着位置と離脱位置との間で、バッテリ６８の取外し方向Ｄ３への移動を規制する。これにより、ユーザがバッテリ装着部６１に装着されたバッテリ６８を取外し方向Ｄ３に移動させた際、バッテリ６８がバッテリ装着部６１から離脱する前に、バッテリ６８の移動が規制される。したがって、バッテリ６８をバッテリ装着部６１から取り外す際に、一度の操作で取り外すことができないため、バッテリ６８の盗難を防ぎ得る。特に、取外し方向Ｄ３が水平面よりも下側に向く方向である場合には、バッテリ６８をバッテリ装着部６１から取り外す際に、バッテリ６８の脱落を抑えることもできる。 The movement restricting unit 661 restricts the movement of the battery 68 in the removal direction D3 between the attachment position and the removal position. Thereby, when the user moves the battery 68 attached to the battery attachment portion 61 in the removing direction D3, the movement of the battery 68 is restricted before the battery 68 is detached from the battery attachment portion 61. Therefore, when removing the battery 68 from the battery mounting portion 61, the battery 68 cannot be removed by a single operation, and thus the battery 68 can be prevented from being stolen. In particular, when the removal direction D3 is a direction that is directed downward from the horizontal plane, the removal of the battery 68 can be suppressed when the battery 68 is removed from the battery mounting portion 61.
　（１．２）実施形態１の詳細
　以下、本実施形態に係る電動自転車１について更に詳細に説明する。 (1.2) Details of Embodiment 1 Hereinafter, the electric bicycle 1 according to the present embodiment will be described in more detail.

　第２の取付部７２は、図３に示すように、バッテリ装着部６１の第２の支持部６４に対して取り付けられ、第２の支持部６４に対する取外し方向Ｄ３への移動が規制される。第２の取付部７２は、本実施形態では、筒状体７０の第１の方向Ｄ１の両端面のうち、第１の取付部７１とは反対側の開口面を塞ぐ。第２の取付部７２は、本実施形態では、筒状体７０に対してねじ留めされて固定される。第２の取付部７２は、図４Ｂに示すように、ベース板７２１と、移動板７２４と、を備える。 As shown in FIG. 3, the second attachment portion 72 is attached to the second support portion 64 of the battery mounting portion 61, and movement in the removal direction D <b> 3 with respect to the second support portion 64 is restricted. In the present embodiment, the second attachment portion 72 closes the opening surface on the opposite side of the first attachment portion 71 among the both end faces of the cylindrical body 70 in the first direction D1. In the present embodiment, the second attachment portion 72 is fixed by screwing to the cylindrical body 70. As shown in FIG. 4B, the second mounting portion 72 includes a base plate 721 and a moving plate 724.
　ベース板７２１は、筒状体７０に対して固定される板である。ベース板７２１は、筒状体７０の第１の方向Ｄ１の両端面のうち、第１の取付部７１とは反対側の開口面を塞ぐようにして、筒状体７０に固定される。ベース板７２１は、第１の受け部７２２を有する。 The base plate 721 is a plate that is fixed to the cylindrical body 70. The base plate 721 is fixed to the cylindrical body 70 so as to close the opening surface on the opposite side of the first attachment portion 71 among the both end faces of the cylindrical body 70 in the first direction D1. The base plate 721 has a first receiving part 722.
　第１の受け部７２２は、後述の第２の支持部６４が有する位置決め部６５２（図３参照）によって、バッテリ装着部６１に対して、取外し方向Ｄ３への移動が規制される。第１の受け部７２２は、本実施形態では、ベース板７２１に対してねじ止めされているが、本開示では、第１の受け部７２２はベース板７２１と一体であってもよい。本開示でいう「一体」とは、二次接着や機械的接合が用いられないことを意味する。第１の受け部７２２は、第１の受け面７２３を有する。第１の受け面７２３は、後述の位置決め部６５２の作用面６５３に対向する。第１の受け面７２３は、作用面６５３に対して当たることで、位置決めの機能を発揮する。 The movement of the first receiving portion 722 in the removal direction D3 is restricted with respect to the battery mounting portion 61 by a positioning portion 652 (see FIG. 3) of the second support portion 64 described later. In the present embodiment, the first receiving portion 722 is screwed to the base plate 721. However, in the present disclosure, the first receiving portion 722 may be integrated with the base plate 721. The term “integrated” in the present disclosure means that secondary bonding or mechanical bonding is not used. The first receiving portion 722 has a first receiving surface 723. The first receiving surface 723 faces an action surface 653 of a positioning portion 652 described later. The first receiving surface 723 exerts a positioning function by abutting against the action surface 653.
　移動板７２４は、ベース板７２１に対して、第１の方向Ｄ１に移動可能である。移動板７２４とベース板７２１との間には、例えば、コイルばね等の弾性体が配置されており、移動板７２４は、第１の方向Ｄ１のうち、ベース板７２１から離れる方向に押されている。したがって、移動板７２４は、自然状態では、ベース板７２１との間に隙間を有し、第１の方向Ｄ１のうちのベース板７２１に近づく方向に押されることで、ベース板７２１に近づくように移動する。一方、移動板７２４を押す力を解くと、移動板７２４は、第１の方向Ｄ１のうちのベース板７２１から離れる方向に移動し、自然状態に戻る。ここで、本開示でいう「自然状態」とは、位置決め以外の外力が加えられていない状態を意味する。 The moving plate 724 is movable in the first direction D1 with respect to the base plate 721. For example, an elastic body such as a coil spring is disposed between the moving plate 724 and the base plate 721, and the moving plate 724 is pushed in a direction away from the base plate 721 in the first direction D1. Yes. Therefore, the moving plate 724 has a gap with the base plate 721 in a natural state, and is pushed in a direction approaching the base plate 721 in the first direction D1, so that the moving plate 724 approaches the base plate 721. Moving. On the other hand, when the force pushing the moving plate 724 is released, the moving plate 724 moves in a direction away from the base plate 721 in the first direction D1 and returns to the natural state. Here, the “natural state” in the present disclosure means a state in which an external force other than positioning is not applied.
　移動板７２４は、少なくとも１つの第２の受け部７２５を有する。本実施形態では、移動板７２４は、複数（ここでは、２つ）の第２の受け部７２５を有する。複数の第２の受け部７２５は、後述の移動規制部６６１に当たる部分であり、これにより、バッテリ６８の取外し方向Ｄ３への移動が規制される。複数の第２の受け部７２５は、本実施形態では、第２の方向Ｄ２に離れている。各第２の受け部７２５は、本実施形態では、移動板７２４に形成された凹部で構成されており、移動規制部６６１に当たる第２の受け面７２６を有する。本実施形態において、第２の受け面７２６は、バッテリ６８がバッテリ装着部６１に装着された状態では移動規制部６６１に対して離れており、第１の受け面７２３が位置決め部６５２から外れると、第２の受け面７２６は移動規制部６６１に当たる。第２の受け面７２６は、移動規制部６６１に対して当たることで、バッテリ６８の取外し方向Ｄ３に沿った移動を規制する機能を発揮する。 The moving plate 724 has at least one second receiving portion 725. In the present embodiment, the moving plate 724 has a plurality of (here, two) second receiving portions 725. The plurality of second receiving portions 725 correspond to a movement restricting portion 661, which will be described later, and thereby the movement of the battery 68 in the removing direction D3 is restricted. The plurality of second receiving portions 725 are separated in the second direction D2 in the present embodiment. In the present embodiment, each second receiving portion 725 is configured by a concave portion formed in the moving plate 724, and has a second receiving surface 726 that hits the movement restricting portion 661. In the present embodiment, the second receiving surface 726 is separated from the movement restricting portion 661 in a state where the battery 68 is mounted on the battery mounting portion 61, and when the first receiving surface 723 is detached from the positioning portion 652. The second receiving surface 726 hits the movement restricting portion 661. The second receiving surface 726 exerts a function of restricting movement of the battery 68 along the removal direction D <b> 3 by contacting the movement restricting portion 661.
　バッテリ装着部６１は、バッテリ６８を装着可能な部分である。ここで、本開示では、バッテリ装着部６１に装着されたバッテリ６８の位置を「装着位置」とし、バッテリ装着部６１から外れたバッテリ６８の位置を「離脱位置」とする。特に、本実施形態では、装着位置は、後述の位置決め部６５２によって、第１の受け部７２２が位置決めされた位置である。装着位置にあるバッテリ６８は、バッテリ装着部６１に対して、取外し方向Ｄ３に沿って移動可能であり、取外し方向Ｄ３に移動することで、バッテリ装着部６１から取り外される。 The battery mounting portion 61 is a portion where the battery 68 can be mounted. Here, in the present disclosure, the position of the battery 68 attached to the battery attachment part 61 is referred to as “attachment position”, and the position of the battery 68 detached from the battery attachment part 61 is referred to as “detachment position”. In particular, in the present embodiment, the mounting position is a position where the first receiving portion 722 is positioned by a positioning portion 652 described later. The battery 68 in the mounting position is movable along the removal direction D3 with respect to the battery mounting portion 61, and is removed from the battery mounting portion 61 by moving in the removal direction D3.
　バッテリ装着部６１は、本実施形態では、下パイプ２０に形成された開口部２９内に配置される。本実施形態において、バッテリ装着部６１は、図３に示すように、ベース６２と、第１の支持部６３と、第２の支持部６４と、配線押さえ具６７とを備える。 The battery mounting portion 61 is disposed in the opening 29 formed in the lower pipe 20 in the present embodiment. In the present embodiment, the battery mounting portion 61 includes a base 62, a first support portion 63, a second support portion 64, and a wiring presser 67, as shown in FIG.
　ベース６２は、バッテリ装着用パイプ２８（本実施形態では、下パイプ２０）の開口部２９に対応する部分の内面に固定される。ベース６２は、第１の方向Ｄ１に延びており、ベース６２の長手方向は、下パイプ２０の長手方向に平行である。ベース６２の第１の方向Ｄ１の両端部のうち、一方の端部には、第１の固定部６２１が形成され、他方の端部には、第２の固定部６２２が形成される。第１の固定部６２１には、第１の支持部６３が取り付けられる。第２の固定部６２２には、第２の支持部６４が取り付けられる。 The base 62 is fixed to the inner surface of the portion corresponding to the opening 29 of the battery mounting pipe 28 (in this embodiment, the lower pipe 20). The base 62 extends in the first direction D1, and the longitudinal direction of the base 62 is parallel to the longitudinal direction of the lower pipe 20. Of the both ends of the base 62 in the first direction D1, a first fixing portion 621 is formed at one end, and a second fixing portion 622 is formed at the other end. A first support portion 63 is attached to the first fixing portion 621. A second support portion 64 is attached to the second fixing portion 622.
　第１の支持部６３は、バッテリ６８の第１の取付部７１を支持し得る部分である。第１の支持部６３は、本実施形態では、第１の取付部７１を第２の方向Ｄ２に沿った軸回りに回転可能に支持する。本実施形態において、第１の支持部６３は、第１の取付部７１の支持凹部７１２に入る支持凸部６３１を有する。支持凸部６３１は、支持凹部７１２に入ることで、第１の取付部７１を支持し得る。 The first support portion 63 is a portion that can support the first attachment portion 71 of the battery 68. In the present embodiment, the first support portion 63 supports the first attachment portion 71 so as to be rotatable about an axis along the second direction D2. In the present embodiment, the first support portion 63 has a support convex portion 631 that enters the support concave portion 712 of the first attachment portion 71. The support convex portion 631 can support the first attachment portion 71 by entering the support concave portion 712.
　支持凸部６３１の先端面６３２は、図５Ａに示すように、第２の方向Ｄ２に直交する断面において、円弧状に形成されている。また、支持凹部７１２の底面７１３も、第２の方向Ｄ２に直交する断面において、円弧状に形成されている。したがって、支持凹部７１２に支持凸部６３１が入ると、支持凸部６３１の先端面６３２と支持凹部７１２の底面７１３とが対向し、支持凸部６３１の先端面６３２と支持凹部７１２の底面７１３とが面接触する。バッテリ６８が取外し方向Ｄ３に移動すると、図５Ｂに示すように、支持凹部７１２の底面７１３は、支持凸部６３１の先端面６３２に対して面接触を保ちながら移動し得る。これにより、バッテリ６８は、支持凹部７１２の底面７１３の円弧の中心を回転軸とした回転移動を行い得る。 The front end surface 632 of the support convex portion 631 is formed in an arc shape in a cross section orthogonal to the second direction D2, as shown in FIG. 5A. The bottom surface 713 of the support recess 712 is also formed in an arc shape in a cross section orthogonal to the second direction D2. Therefore, when the support convex portion 631 enters the support concave portion 712, the tip surface 632 of the support convex portion 631 and the bottom surface 713 of the support concave portion 712 face each other, and the tip surface 632 of the support convex portion 631 and the bottom surface 713 of the support concave portion 712 Makes surface contact. When the battery 68 moves in the removal direction D3, as shown in FIG. 5B, the bottom surface 713 of the support recess 712 can move while maintaining surface contact with the tip surface 632 of the support projection 631. As a result, the battery 68 can perform rotational movement about the center of the arc of the bottom surface 713 of the support recess 712 as the rotation axis.
　第２の支持部６４は、バッテリ６８の第２の取付部７２を支持し得る部分である。第２の支持部６４は、本実施形態では、バッテリ６８を装着位置に位置させ、バッテリ６８をバッテリ装着部６１に対して位置決めする。第２の支持部６４は、図３に示すように、位置決め機構部６５と、移動規制体６６とを備える。 The second support portion 64 is a portion that can support the second mounting portion 72 of the battery 68. In the present embodiment, the second support portion 64 positions the battery 68 at the mounting position and positions the battery 68 with respect to the battery mounting portion 61. As shown in FIG. 3, the second support portion 64 includes a positioning mechanism portion 65 and a movement restricting body 66.
　位置決め機構部６５は、位置決め部６５２を支持位置と非支持位置とに切替可能であり、支持位置に切り替えられることで、バッテリ６８をバッテリ装着部６１に対して位置決めし得る部分である。ここで、本開示でいう「支持位置」とは、バッテリ６８の第２の取付部７２を支持し得る位置を意味する。本開示でいう「非支持位置」とは、バッテリ６８の第２の取付部７２を支持しない位置を意味する。位置決め機構部６５は、本実施形態では、本体部６５１と、位置決め部６５２と、解除操作部６５５とを備える。 The positioning mechanism portion 65 is a portion that can switch the positioning portion 652 between a support position and a non-support position, and can position the battery 68 with respect to the battery mounting portion 61 by switching to the support position. Here, the “support position” in the present disclosure means a position where the second mounting portion 72 of the battery 68 can be supported. The “non-supporting position” in the present disclosure means a position where the second attachment portion 72 of the battery 68 is not supported. In this embodiment, the positioning mechanism unit 65 includes a main body unit 651, a positioning unit 652, and a release operation unit 655.
　本体部６５１は、位置決め機構部６５の主体を構成する部分である。本体部６５１は、ベース６２の第２の固定部６２２に取り付けられ、第２の固定部６２２に対して固定される。 The main body portion 651 is a portion constituting the main body of the positioning mechanism portion 65. The main body portion 651 is attached to the second fixing portion 622 of the base 62 and is fixed to the second fixing portion 622.
　位置決め部６５２は、バッテリ６８を装着位置で位置決めし得る部分である。位置決め部６５２は、図６Ａ、図６Ｂに示すように、本実施形態では、支持位置（図６Ａ参照）と非支持位置（図６Ｂ参照）との間で往復移動し得る。位置決め部６５２において、支持位置は、本体部６５１から、第１の方向Ｄ１のうちのバッテリ６８側に向かう方向に、所定寸法以上、突出した位置である。これにより、支持位置にある位置決め部６５２は、バッテリ６８の第１の受け部７２２を位置決めする。ここでいう「所定寸法」とは、バッテリ６８の第１の受け部７２２を位置決めし得る寸法であり、本体部６５１とバッテリ６８の第１の受け部７２２との間の寸法に応じて適宜変更され得る。 The positioning portion 652 is a portion where the battery 68 can be positioned at the mounting position. As shown in FIGS. 6A and 6B, the positioning portion 652 can reciprocate between a support position (see FIG. 6A) and a non-support position (see FIG. 6B) in this embodiment. In the positioning part 652, the support position is a position protruding from the main body part 651 by a predetermined dimension or more in the direction toward the battery 68 in the first direction D1. Thereby, the positioning part 652 in the support position positions the first receiving part 722 of the battery 68. The “predetermined dimension” here is a dimension capable of positioning the first receiving part 722 of the battery 68, and is appropriately changed according to the dimension between the main body part 651 and the first receiving part 722 of the battery 68. Can be done.
　位置決め部６５２において、非支持位置は、第１の方向Ｄ１において、支持位置よりも本体部６５１に近い位置である。本開示では、非支持位置は、位置決め部６５２の移動範囲のうち、支持位置以外の位置を意味する。位置決め部６５２は、本体部６５１に内蔵されたコイルばね等の弾性体によって、支持位置に向かって押されており、要するに、位置決め部６５２は、自然状態では、支持位置に位置する。 In the positioning portion 652, the non-supporting position is a position closer to the main body 651 than the supporting position in the first direction D1. In the present disclosure, the non-supporting position means a position other than the supporting position in the movement range of the positioning unit 652. The positioning portion 652 is pushed toward the support position by an elastic body such as a coil spring built in the main body portion 651. In short, the positioning portion 652 is positioned at the support position in the natural state.
　位置決め部６５２は、本実施形態では、作用面６５３と、傾斜面６５４とを備える。作用面６５３は、バッテリ６８の第１の受け部７２２に当たって、第１の受け面７２３を支持し得る。作用面６５３は、本実施形態では、取外し方向Ｄ３に対して交差しており、より詳細には、取外し方向Ｄ３に対して直交する。ここでいう「直交」とは、取外し方向Ｄ３とのなす角が９０°のみを意味するのではなく、第１の受け部７２２の第１の受け面７２３をバッテリ装着部６１に対して位置決めすることができれば、例えば、±５°程度は「直交」であることの範疇である。 The positioning portion 652 includes an action surface 653 and an inclined surface 654 in the present embodiment. The working surface 653 can contact the first receiving portion 722 of the battery 68 and support the first receiving surface 723. In the present embodiment, the working surface 653 intersects the removal direction D3, and more specifically, is perpendicular to the removal direction D3. Here, “orthogonal” does not mean that the angle formed by the removal direction D3 is only 90 °, but the first receiving surface 723 of the first receiving portion 722 is positioned with respect to the battery mounting portion 61. If possible, for example, about ± 5 ° is a category of “orthogonal”.
　傾斜面６５４は、取付け方向に他の部材が当たると、位置決め部６５２を支持位置から非支持位置に移動させる。傾斜面６５４は、本実施形態では、取付け方向に対して傾斜しており、かつ第１の方向Ｄ１のうちのバッテリ６８側に向かう方向に進むほど取付け方向に進むような勾配を有する。傾斜面６５４は、本実施形態では、第２の方向Ｄ２に直交する断面において、円弧状である。したがって、傾斜面６５４に対して、取付け方向に移動するバッテリ６８の少なくとも一部が当たると、位置決め部６５２は、非支持位置に向かって移動する。 The inclined surface 654 moves the positioning portion 652 from the support position to the non-support position when another member hits in the mounting direction. In the present embodiment, the inclined surface 654 is inclined with respect to the attachment direction, and has a gradient that advances in the attachment direction as it goes in the direction toward the battery 68 in the first direction D1. In the present embodiment, the inclined surface 654 has an arc shape in a cross section orthogonal to the second direction D2. Therefore, when at least a part of the battery 68 moving in the attachment direction hits the inclined surface 654, the positioning portion 652 moves toward the non-supporting position.
　解除操作部６５５は、位置決め部６５２によるバッテリ６８の位置決めを解除する。解除操作部６５５は、本実施形態では、ユーザ等の操作により、位置決め部６５２によるバッテリ６８の位置決めを解除することができる。解除操作部６５５は、本実施形態では、シリンダ錠６５６を有しており、シリンダ錠６５６を操作することで、位置決め部６５２を非支持位置に切り替えることができる。具体的には、シリンダ錠６５６の鍵穴６５７に鍵を差し入れた状態で、鍵をシリンダ錠６５６の回転軸回りに回転させると、位置決め部６５２は非支持位置に切り替えられる（図６Ａから図６Ｂ）。なお、本実施形態では、鍵を鍵穴６５７に差し入れたままでは、位置決め部６５２は非支持位置に保たれるが、鍵を鍵穴６５７から引き抜くと、位置決め部６５２は支持位置に切り替えられる。解除操作部６５５の先端面は、下パイプ２０から露出する。 The release operation unit 655 releases the positioning of the battery 68 by the positioning unit 652. In this embodiment, the release operation unit 655 can release the positioning of the battery 68 by the positioning unit 652 by an operation of a user or the like. In this embodiment, the release operation unit 655 has a cylinder lock 656, and by operating the cylinder lock 656, the positioning unit 652 can be switched to the non-supporting position. Specifically, when the key is rotated around the rotation axis of the cylinder lock 656 with the key inserted into the key hole 657 of the cylinder lock 656, the positioning portion 652 is switched to the non-supporting position (FIGS. 6A to 6B). . In this embodiment, the positioning unit 652 is kept in the non-supporting position while the key is inserted into the key hole 657, but when the key is pulled out from the key hole 657, the positioning unit 652 is switched to the support position. The distal end surface of the release operation unit 655 is exposed from the lower pipe 20.
　移動規制体６６は、バッテリ６８が装着位置から離脱位置に向かう間に、バッテリ６８の取外し方向Ｄ３の移動を規制するための部材である。移動規制体６６は、位置決め機構部６５に取り付けられ、位置決め機構部６５に対して固定される。移動規制体６６は、複数（本実施形態では２つ）の移動規制部６６１を有する。 The movement restricting body 66 is a member for restricting the movement of the battery 68 in the removal direction D3 while the battery 68 moves from the mounting position to the removal position. The movement restricting body 66 is attached to the positioning mechanism unit 65 and fixed to the positioning mechanism unit 65. The movement restricting body 66 has a plurality (two in this embodiment) of movement restricting portions 661.
　複数の移動規制部６６１は、装着位置と離脱位置との間で、バッテリ６８の取外し方向Ｄ３への移動を規制する。各移動規制部６６１は、第１の方向Ｄ１のうちのバッテリ６８側に向かう方向に延びている。複数の移動規制部６６１は、複数の第２の受け部７２５に対応しており、複数の第２の受け部７２５に対して一対一で入る。ただし、本開示では、１つの移動規制部６６１でもよく、要するに少なくとも１つの移動規制部６６１があればよい。また、２つの第２の受け部７２５に対して、１つの移動規制部６６１であってもよい。本実施形態では、位置決め部６５２が非支持位置に切り替えられたときに、図６Ｂに示すように、バッテリ６８が取外し方向Ｄ３に移動しても、複数の移動規制部６６１に対して複数の第２の受け部７２５が引っ掛かる。すると、複数の第２の受け部７２５は、取外し方向Ｄ３に沿ったバッテリ６８の移動を規制し得る。ここでいう「バッテリ６８の移動」とは、本実施形態では、第１の支持部６３の支持凸部６３１による第２の方向Ｄ２に沿った軸回りの回転移動を意味する。ただし、本開示では、移動規制部６６１によるバッテリ６８の移動は、回転移動に限らず、バッテリ６８の平行移動（直線移動）であってもよい。 The plurality of movement restriction portions 661 restrict movement of the battery 68 in the removal direction D3 between the attachment position and the removal position. Each movement restricting portion 661 extends in a direction toward the battery 68 in the first direction D1. The plurality of movement restricting portions 661 correspond to the plurality of second receiving portions 725 and enter the plurality of second receiving portions 725 on a one-to-one basis. However, in the present disclosure, one movement restriction unit 661 may be provided, and in short, at least one movement restriction unit 661 may be provided. Further, one movement restricting portion 661 may be provided for the two second receiving portions 725. In the present embodiment, when the positioning unit 652 is switched to the non-supporting position, as shown in FIG. The second receiving portion 725 is caught. Then, the plurality of second receiving portions 725 can regulate the movement of the battery 68 along the removal direction D3. In this embodiment, the “movement of the battery 68” means a rotational movement around the axis along the second direction D2 by the support convex portion 631 of the first support portion 63. However, in the present disclosure, the movement of the battery 68 by the movement restriction unit 661 is not limited to the rotational movement, and may be a parallel movement (linear movement) of the battery 68.
　ここで、本実施形態に係るバッテリ装置６では、図１に示すように、フレーム２に対し、バッテリ６８の取外し方向Ｄ３が水平面よりも下側に向く方向である（要するに、バッテリの取外し方向Ｄ３は、水平面に対して角度を持ち、かつ下側に向かう方向である）。ここでいう「水平面に対して角度を持つ」とは、取外し方向Ｄ３と水平面とのなす角度θが、０°＜θ＜１８０°であることを意味する。つまり、「水平面に対して角度を持つ」ことには、取外し方向Ｄ３と水平面とが直交することを含むが、取外し方向Ｄ３と水平面とが平行であることは含まない。 Here, in the battery device 6 according to the present embodiment, as shown in FIG. 1, the removal direction D3 of the battery 68 is directed downward from the horizontal plane with respect to the frame 2 (in short, the battery removal direction D3 Is an angle with respect to a horizontal plane and is directed downward. Here, “having an angle with respect to the horizontal plane” means that the angle θ formed by the removal direction D3 and the horizontal plane is 0 ° <θ <180 °. That is, “having an angle with respect to the horizontal plane” includes that the removal direction D3 and the horizontal plane are orthogonal to each other, but does not include that the removal direction D3 and the horizontal plane are parallel.
　したがって、位置決め部６５２によるバッテリ装着部６１に対するバッテリ６８の位置決めが解かれると、バッテリ６８は、重力の作用により、取外し方向Ｄ３に移動し得る。本実施形態に係る電動自転車１では、ユーザ等が解除操作部６５５を操作し、位置決め部６５２を非支持位置に切り替えると、バッテリ装着部６１に対するバッテリ６８の位置決めが解かれ、バッテリ６８が、装着位置から離脱位置に向かって移動し得る。 Therefore, when the positioning of the battery 68 relative to the battery mounting portion 61 by the positioning portion 652 is released, the battery 68 can move in the removal direction D3 due to the action of gravity. In the electric bicycle 1 according to the present embodiment, when the user or the like operates the release operation unit 655 and switches the positioning unit 652 to the non-supporting position, the positioning of the battery 68 with respect to the battery mounting unit 61 is released, and the battery 68 is mounted. It can move from the position toward the disengagement position.
　本実施形態に係るバッテリ装置６は、複数の移動規制部６６１を有しており、この移動規制部６６１によって、装着位置と離脱位置との間で、取外し方向Ｄ３に沿ったバッテリ６８の移動を規制することができる。このため、このため、本実施形態のバッテリ装置６によれば、バッテリ装着部６１からバッテリ６８が落下することを抑えることができる。 The battery device 6 according to the present embodiment includes a plurality of movement restricting portions 661, and the movement restricting portions 661 allow the battery 68 to move along the removal direction D3 between the attachment position and the removal position. Can be regulated. For this reason, according to the battery apparatus 6 of this embodiment, it can suppress that the battery 68 falls from the battery mounting part 61. FIG.
