PROBLEM TO BE SOLVED: To provide a battery mounting structure capable of easily removing a battery.SOLUTION: A battery mounting structure comprises: a holder main body 30； a cover member 40 having a pivot part 45 pivoted by the holder main body 30 so that it can be changed to a close attitude and an open attitude to the holder main body 30； and an operation member 50 provided on the cover member 40. An engaging part 52 fixing the cover member 40 in the close attitude to the holder main body 30, and guide parts 35 and 46 guiding the cover member 40 so as to operate between the close attitude and the open attitude and restricting an opening operation of the cover member 40 in the open attitude, are provided over at least any one of the cover member 40 and the operation member 50, and the holder main body 30. A position of the pivot part 45 is set so that a partial region of the battery 20 is located on the operation member 50 side to the pivot part 45, and an operation position 54 of the operation member 50 is set to an opposite side to a centroid G of the battery 20 to the pivot part 45.【課題】バッテリの取り外しが容易なバッテリ取付構造を提供する。【解決手段】ホルダ本体３０と、ホルダ本体３０に対して閉じ姿勢と開き姿勢とに変更可能となるよう、ホルダ本体３０に枢支される枢支部４５を有するカバー部材４０と、カバー部材４０に設けられた操作部材５０とを備え、ホルダ本体３０に対してカバー部材４０を閉じ姿勢で固定する係合部５２と、カバー部材４０が閉じ姿勢と開き姿勢との間で動作するよう案内し、開き姿勢においてカバー部材４０の開き動作を規制するガイド部３５，４６とが、カバー部材４０及び操作部材５０の少なくとも何れか一方とホルダ本体３０とに亘って設けられ、バッテリ２０の一部の領域が枢支部４５に対し操作部材５０の側に位置するよう、枢支部４５の位置が設定されるとともに、操作部材５０の操作位置５４を、枢支部４５に対しバッテリ２０の重心Ｇとは反対側に設定した。【選択図】図４
