The purpose of the present invention is to maintain a better usability and a better electrical connection, while restricting burden on an attachment portion of an electric tool. In an attachment portion (7) of a chain saw (1) to which a battery pack is mounted, a pair of ribs (15, 15) are provided parallel to and on outer surfaces of the guide rails (10, 10). On the contrary, a connecting member (32) of a remote control holder (30) has a connecting wall (35) positioned outside the guide rails (10, 10) and having a pair of recessed grooves (38, 38) for allowing the pair of ribs (15, 15) to be fitted into the recessed grooves. The chain saw (1) can be connected to the connecting member (32) without utilizing the guide rails (10, 10) and by the engagement between the ribs (15, 15) and the connecting wall (35). |
