PURPOSE:To make the connecting work easy and prevent the poor connection by engaging a mounting protrusion of a terminal block with a terminal block mounting port of an apparatus body and displacing the terminal block so as to come near the electric source wire inserting hole. CONSTITUTION:A terminal block mounting hole 6 provided on the bottom face of an apparatus body 1 is formed of a large hole part 6a and a small hole part 6b, and a mounting protrusion 7 engaged with the terminal block mounting hole 6 is formed on the terminal block 5. This mounting protrusion 7 is formed of an engaging part 7a engaged with the small hole part 6b and a protruded head 7b provided on the upper end of said engaging part 7a. The connection with an electric source wire B is carried out before the terminal block 5 is mounted to the bottom face of the apparatus body 1. Namely, after the mounting protrusion 7 of the terminal block 5 is passes through the large hole part 6a in the terminal block mounting hole 6 of the tool body 1, the terminal block 5 is slided toward the direction of an electric source through port 4 to engage the engaging part 7a of the mounting protrusion 7 with the small hole part 6b of the terminal mounting hole 6 followed by fixing. As no tensile force is given to the electric source wire, poor connection of the terminal block and the electric source wire can be eliminated. |
