Abstract

Abstract The present invention provides novel applications of a battery pack, which is detachably attached to specific power-driven tools. A battery holder of the invention is applicable as a separate power source of portable electrical appliances used for and in automobiles. A body (2) of a battery holder (1) is a flat box-like part including an upper housing (3) and a lower housing (4), which are separable from and joined with each other by means of a plurality of bolts (5). A metal hook (6) projected from the lower housing (4) is held and fixed between the upper housing (3) and the lower housing (4). A shoulder belt or hand strap (8) with both ends thereof held by a pair of pins (7,7) extending from the lower housing (4) to the upper housing (3) is attached to the body (2) for making the battery holder (1) handy to carry. A socket element (9) formed on one shorter side of the body (2) is connectable with a cigar lighter plug. An inlet (11) of a battery pack (14) and a cover plate (12) for opening and closing the inlet (11) are provided on the other shorter side of the body (2).
