PROBLEM TO BE SOLVED: To favorably reduce variations of the relative positions of the bottom for cooling of each circuit module, the topside for mounting of a circuit board on the second stage, the main surface of a connecting terminal, etc. SOLUTION: A coupling member 4 has a function of coupling each circuit module 1 with the next by press fitting, and a function of bearing a control circuit board 14 on the second stage by the topside for circuit board fast sticking to which a circuit board 1a is to stick fast. This way, the adhesion between the control circuit board 14 on the second stage where each circuit module 1 is mounted and the topside for circuit board fast sticking of each coupling member 4 bearing it is automatically improved by controlling the quantity of press fitting into the circuit module 1 of each coupling member 4, so a two- stage type of electronic circuit device which has a plurality of circuit modules can be materialized by simple constitution. Moreover, the backside of the circuit board 1a of each circuit module 1 can be leveled into the same plane at the same time with the leveling of the topside of the coupling member 4, by press. |
