<P>PROBLEM TO BE SOLVED: To provide a board fixing structure that prevents or reduces play or overstress of a wiring board when holding the wiring board in a base body and a cover body by absorbing dimensional variations thereof. <P>SOLUTION: A wiring board 1 is provided with one circularly sectioned through hole 11 penetrating in a thickness direction in each corner portion in correspondence with projecting portions 21, 31. A tip portion of the projecting portion 21 of a base body 2 is formed in a conical rib 22 as a radially contracted portion continuously radially contracted (tapered) toward the tip (upper end). The conical rib 22 has a continuous radial change in an insertion direction so as to coaxially enter the through hole 11 of the wiring board 1 from the tip side and, in the inserted state (mounted state) in the through hole 11, slantingly touch an insertion side inner circumferential edge (lower inner circumferential edge) of the through hole 11. <P>COPYRIGHT: (C)2012,JPO&INPIT |
