<p><P>PROBLEM TO BE SOLVED: To provide an electronic control unit capable of simply completely stopping the function of the unit without using a special implement. <P>SOLUTION: The electronic control unit includes a unit case 10, a circuit board 30 housed in the case, a conductive member 21 mounted in the unit case, a continuity point 31 which electrically connects an electronic circuit and the conductive member by engaging with a contact point part of the conductive member to be electrically conductive when the circuit board is positioned at the right position, and an insulating point 32 which is provided on the circumference of the circle with the rotating center of the circuit board on the board surface of the circuit board as a center, and shields the continuity of the contact point with the electronic circuit to hold the state by engaging with the contact point of the conductive member when the circuit board is rotated from the right position to the operation position in case of failure. A groove 16 is provided on a pair of side walls 11 mutually opposed to the unit case, and the circuit board is rotatably supported in the unit case by the insertion of a circular arc shape outer peripheral part of the circuit board into the groove. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
