PROBLEM TO BE SOLVED: To arrange a first connector and a second connector, mounted on a single substrate, back to back on a pair of opposite case walls although a bus extension structure of a plurality of control units constituted such that the plurality of control units are arranged in parallel and a bus is extended by connector-connecting control units on the opposite bonded case walls can be manufactured at a low price. SOLUTION: The first connector 24 coupled and fixed to a substrate 21 is disposed to be exposed to outside one of the case side walls in a unit parallel direction, and a cable 26 lead out of the second connector 25 which can be connected to and separated from the first connector 24 is connected to the substrate 21, and the second connector 25 is supported on the case side wall to be exposed to outside the other case side wall in the unit parallel direction, and the first connector 24 and second connector 25 are disposed back to back at mutually opposite positions of the opposite case side walls of the control units 2.
