PROBLEM TO BE SOLVED: To prevent rain water or dust from invading into a battery-storing part 9 in an empty state, and to improve convenience by allowing a lid body 34 to be opened or closed according to the inserting or extracting operation of a battery case 10 into or from the battery-storing part 9 in an electrically driven tending machine.SOLUTION: The lid body 34 turnably supported by a horizontal spindle 33 is installed at the upper side of the battery-storing part 9 in the near side of an opening part 30, and is constituted so as to change the posture from a closed posture of the opening part 30 to an insertion-allowing posture by the insertion operation of the battery case 10 into the battery-storing part 9, and so as to change the posture to the closed posture of the opening part 30 by the extraction operation of the battery case 10. The lid body 34 is urged so as to close the opening part 30 by constantly moving the lid body 34 downward to the lower end side through an urging means such as a torsion spring. When the battery-storing part 9 is empty, a stepped part 35 being a stopper for closing the opening part 30 by the contact with the lower end part of the lid body 34 is integrally formed at the bottom plate 27a.COPYRIGHT: (C)2010,JPO&INPIT【課題】空の状態のバッテリ収納部9内に雨水やほこりが侵入しないようにするとともにバッテリ収納部9内へのバッテリケース10の挿抜操作に応じて蓋体34が開閉動作することで簡便性を向上させる。【解決手段】バッテリ収納部9の上側であって、開口部30に近い側には、横支軸33に回動可能に支持された蓋体34が設けられ、この蓋体34は、バッテリ収納部9内へのバッテリケース10の挿入動作により開口部30の閉止姿勢から挿入可能姿勢へと姿勢変更し、バッテリケース10の抜き出し動作により開口部30の閉止姿勢へと姿勢変更するように構成されている。そして、蓋体34は、捩じりバネなどの付勢手段を介して下端側常時下向きに移動して開口部30を閉止するように付勢されている。バッテリ収納部9が空状態の時、蓋体34の下端部が当接して開口部30を塞ぐためのストッパとなる段部35が底板27aに一体的に形成されている。【選択図】図5
