Abstract

PROBLEM TO BE SOLVED: To provide a member joining structure excellent in junction strength and simple in structure. SOLUTION: Two members 10, 11 are joined together by pressing oblong plates 12 into fitting holes 10a, 11a in a beam, and therefore the fitting holes 10a, 11a should be cut as holes with U-shaped inner peripheries, and fitting holes of such a shape can be cut at low cost. The oblong plates 12 are locked in the fitting holes 10a, 11a by passing a pin 13 through pin holes 10b, 11b, so that the two members 10, 11 can be firmly joined together. Further, if necessary an adhesive is applied to the oblong plates 12 and the oblong plates 12 are pressed into and bonded to the fitting holes 10, 11a, in which case the two members 10, 11 can be more firmly joined together as the oblong plates 12 can be securely locked in the fitting holes 10a, 11a.
