將電池40收容於電池殼體41內時,首先,打開踏板面板9b而使電池插拔口41a開放。將設為前方抬高之傾斜姿勢之電池40相對於該電池插拔口41a而自後下部***。其次,使電池40以後下部為支點而旋動成使前上部移動至下方,以此將電池40整體收容於電池殼體41內。其次,藉由鎖定機構將電池40之脫離鎖定。又,關閉踏板面板9b而將電池插拔口41a閉合,以此完成電池40之收容。When storing the
於電池40之以上述傾斜姿勢朝向前上方之頂部,設置有用以提取電池40之提手。於電池40之以上述傾斜姿勢朝向後下方之底部,設置有能裝卸地連接電池側連接端子(未圖示)。在位於電池殼體41之後端之底壁部,設置有能裝卸地連接上述電池側連接端子之殼體側連接端子42。殼體側連接端子42藉由插拔電池40時之旋動而使上述電池側連接端子裝卸。電池殼體41亦可為如下構成,即,根據上述鎖定機構之鎖定操作而使殼體側連接端子42出現或隱藏,使上述電池側連接端子裝卸。At the top of the
參照圖3、圖4,於電池殼體41之後下部,設置有電纜取出部41b。電纜取出部41b係為了將自殼體側連接端子42延伸之輸出電纜(高壓線)43取出至殼體外而設置。自電纜取出部41b導出至殼體外之輸出電纜43***至接近於電池殼體41後方之擺動單元20之前部(橫向部25)。該輸出電纜43連接於橫向部25內之功率控制單元32。3 and 4, a
