PROBLEM TO BE SOLVED: To simplify a structure for fitting a board mounted with a terminal block into a case, and to prevent trouble accompanying attachment and detachment of a connection cable to and from the terminal block. SOLUTION: An elastic engagement claw 7 for snap-fit coupling to a rear side portion of a circuit board 2 is provided at an inner surface portion of a board fitting wall portion 1a of a lower case 1. A plurality of a first fixer 8 and a second fixer 9 are provided on an inner surface portion of the board fitting wall portion 1a at positions shifting to the right and left corresponding to a front side portion of the circuit board 2. The first fixer 8 has an upper end bent in an L shape to lock an edge surface of the front side of the circuit board 2, and the second fixer 9 abuts against the back surface of the front side portion of the circuit board 2 to support it from below. The board fitting wall portion 1a is provided with a plurality of columnar ribs 10 receiving the back surface of the circuit board 2 where a terminal block 4 mounting portion of the circuit board 2 is clamped from before and behind with the second fixer 9.
