To prevent a battery case from being displaced even if there are rough driving operations and the unevenness of a road surface so as to stabilize a current flow at an electrical connection portion and a power feeding to a motor driving unit.SOLUTION: A battery device includes: an attachment base that is fastened on a handle; and a battery case 8 that is placed on the attachment base so as to be detachable. An electrical connection portion 60 that electrically connects a motor driving unit and a battery together is provided at a position where the attachment base and the battery case 8 face with each other. Right and left guide portions each having guiding surfaces at an external side, an upper side and a lower side, and a latch bolt pushed so as to protrude from an upper surface of the attachment base are provided on the attachment base. Right and left side portions 80 each including sliding surfaces 81 to 83 which are engaged with the external, upper and lower guiding surfaces of each guide portion, respectively, and which are slidable along the respective guiding surfaces, and a latch hole 104 where the latch bolt is fitted in are provided at a lower surface of the battery case 8.SELECTED DRAWING: Figure 4

    【課題】荒い運転操作や路面の凹凸があっても、バッテリーケースが変位しないようにし、電気接続部での通電及びモータ駆動部へ給電を安定させる。【解決手段】バッテリー装置は、ハンドル上に固定される取付ベースと、取付ベース上に取外し可能に定置されるバッテリーケース8とを含む。取付ベースとバッテリーケース8との対向位置にモータ駆動部とバッテリーとの間を電気接続する電気接続部60が設けられる。取付ベース上には外側及び上下に案内面を有する左右のガイド部と、取付ベースの上面より突出するように付勢されるラッチボルトとが設けられる。バッテリーケース8の下面にはガイド部の外側及び上下の各案内面に係合し各案内面に沿って摺動が可能な摺動面81~83を有する左右のスライド部80と、ラッチボルトが嵌合するラッチ穴104とが設けられる。【選択図】図4
