PROBLEM TO BE SOLVED: To solve the problem wherein a conventional motor terminal box keeps a power cable orthogonal to a terminal block so that the electric wire length is shortened when a terminal to be connected is at the center and made longer when at both ends, and as a result longer working time is required and the electric wire may be damaged by forcible work due to such a structure, and also the terminal box body must be enlarged for a terminal block having many terminals, which causes a difficulty in installing a motor. SOLUTION: The terminal blocks are structured at both sides to face each other in the parallel direction to the leading-in direction of the power cable, or arranged at three directions of both right and left sides and a front to the leading-in direction of the power cable. Wiring work is performed without changing the electric wire length by making further uniform the distances from the led-in power cable to the terminal fittings to be connected. Furthermore, by arranging the terminal blocks at the three directions to the led-in power cable, the dimensions of the motor terminal box is prevented from being enlarged, even when there are many terminals.
