<P>PROBLEM TO BE SOLVED: To provide a circuit board support structure which enables enlargement of a mounting space of an electronic component to a circuit board whose size is reduced. <P>SOLUTION: A circuit board support structure comprises: a slit part 201A formed on one part of one end edge in a rectangular outer shape; a circuit board 201 in which fastening member insertion parts 201B, 201C are provided on plural parts on an end edge facing the end edge on which the slit part is provided but four corners are not fastened; a projection 210' having a shape capable of fitting into the slit part at a circuit board supporting position in a chassis or an electrical box; and fastening holding parts 220A, 220B having fastening parts provided corresponding to the positions of the fastening member insertion parts. In the structure, the projection serves as an oscillation supporting point of the circuit board in the case where the slit part is inserted, and after oscillation, one end edge in the longitudinal direction of the slit part on the circuit board mounted on the fastening holding part is caused to abut thereon so that fastening positions of the circuit board and the fastening holding part correspond to each other. <P>COPYRIGHT: (C)2013,JPO&INPIT |
