PURPOSE: To prevent the generation of a shearing force or the like by inserting a bonding end of a beam member into an opening of a post member and pene trating a sleeve buried in the bonding end and locking a shaft, which turns relatively with the sleeve, with the post member. CONSTITUTION: A bonding end of a beam member 1 is inserted into the opening 5 of a post member 2 where a shaft 4, which penetrates the post member 2 is locked with a sleeve 3 aligned with the center of a locking hole 6, thereby connecting the beam member 1 to the post member 2. In the case where a tensile force is produced as an axial force of the beam member 1, an allowable compression stress of the beam member 1 is specified to beσb1 and an allowable shear stress isτs1 and the outside diameter of the sleeve is W1 and the distance from the end face of the beam member 1 to the sleeve 3 is L1 , the following equation of L1 >σb1×W1 /2τs1 is satisfied. At the same time when the allowable compression stress of the post member 2 is 7.2 and the allowable shear stress isτs2 and the outside diameter of the shaft in the area locked with the post member 2 is W2 and the distance from the side surface of the post member on the beam member side to the shaft 3 is L2 , the following equation must be satisfied: L2 >σb2 /W2 /2τs2 .
