<P>PROBLEM TO BE SOLVED: To prevent an electronic circuit board from being incorrectly assembled into a case in an electronic control device. <P>SOLUTION: Fitting pins 3d, which are provided at a case 3, are placed so as to be rotary asymmetrical when viewed from a direction that an electronic circuit board 2 is assembled into a case. Further, in response to the arrangement of the fitting pins 3, fitting holes 2c, which are respectively engaged with the fitting pins on the electronic circuit board, are placed so as to be rotary asymmetrical as with the fitting pins. In this arrangement, unless the electronic circuit board is correctly placed relative to the case, the fitting pins interfere with the electronic circuit board and the electronic circuit board is not assembled to the case. <P>COPYRIGHT: (C)2012,JPO&INPIT |
