Zusammenfassung: | PROBLEM TO BE SOLVED: To smoothly slide a movable plate 25 along a guide rod 27 even if the movable plate 25 inclines in a direction 44 orthogonal to the guide rod 27.SOLUTION: A pressing device for a film exterior battery has a guide rod 27 passing through a plurality of movable plates 25 and fixed to a housing. With the film external battery arranged between two adjacent movable plates 25, the movable plates 25 are pressed in a direction in which they come close to each other, thereby pressing the film external battery 11. Guide holes 26 in the movable plates 25 through which the guide rod 27 passes through is provided with a straight part 41 forming a cylindrical face that is constant in radial dimension in a plate thickness direction 40; and tapering parts 42, 43, gradually increasing in radial dimension away from the central part of the movable plate 25 in the plate thickness direction 40.
【課題】 可動プレート25がガイドロッド27の直交方向44に対して傾いても、可動プレート25をガイドロッド27に沿って円滑に摺動させる。【解決手段】 複数の可動プレート25を貫通してハウジングに固定されるガイドロッド27を有する。隣り合う2つの可動プレート25の間にフィルム外装電池を配置した上で、可動プレート25を互いに近づく方向に押圧することで、フィルム外装電池11を加圧する。ガイドロッド27が貫通する可動プレート25のガイド孔26に、径方向寸法が板厚方向40で一定の円筒面をなす直線部41と、可動プレート25の中央部から離間するにしたがって径方向寸法が板厚方向40で徐々に拡大するテーパ部42,43と、を設ける。【選択図】図9 |
