<P>PROBLEM TO BE SOLVED: To provide a control unit which reduces the number of assembling steps when mounting a plurality of boards within a shell. <P>SOLUTION: A transmission unit (control unit) 2 includes a body, a power supply board 22, a control board 23 and a cover 24 attached onto the body. The power supply board 22 and the control board 23 are fixed within the cover 24 being faced each other. The power supply board 22 has cutouts 22b, the diameter of which is larger than the diameter of the head of fixing screws 23a, at positions corresponding to dispositions 23b of the fixing screws 23a for fixing the control board 23. With this arrangement, the control board 23 and the power supply board 22, which are connected to each other via a connector, can be fixed with screws to the cover 24 at the same time. Thus, the number of assembling steps can be reduced when mounting the control board 23 and the power supply board 22 within the transmission unit 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
