Abstract: A battery carrier configured to be mounted to a tool body of an electric tool for supplying electric power to the tool body may include a plurality of battery mount sections arranged in a juxtaposed relationship, each battery mount section may be configured to hold a battery that has a length along a longitudinal direction, the length of each mounted battery may be substantially the same, and the battery mount sections may be arranged and configured so that when batteries are mounted on the battery mount sections, longitudinal axes of the respective batteries mounted to the battery mount sections may extend at least partially parallel to each other.

Abstract: A battery device that functions as a power source of a tool main body and is attachable to a body of a user may include a battery housing that is capable of removably receiving at least one rechargeable battery and capable of being electrically connected to the at least one battery, an adaptor that is capable of being electrically connected to the tool main body, and a cable electrically connecting the battery housing and the adaptor. The battery housing comprises a housing body that is constructed to be attached to the body of the user and is capable of receiving the at least one battery therein, and a cover member that is openably and closably attached to the housing body. The housing body and the at least one battery are connected to each other via a male-female engagement device. The male-female engagement device has an engagement release portion that is positioned so as to be exposed when the cover member is opened relative to the housing body.

Abstract: A tool storage bag includes a hexahedral fabric bag body and openable only at a top side or at the top side and a bottom side, and an interlining material at least provided at three adjoining sides of the bag body. The interlining material includes plural flat plates corresponding to the three sides. At least one of the flat plates is detachable from a corresponding one of the sides of the bag body, while the bag body is foldable without folding the sides provided with the interlining material. The bag body with at least one flat plate detached from the corresponding side is folded down by overlapping, on one of the unfoldable sides of the bag body, the side other than the above one side and provided with the interlining material.
