  For this reason, when the axial force N acts on the joint J3 between the first wood 36 and the second wood 38, the fitting member 40 bites into the wedge surfaces 36AH and 38AH against the compressive force, and against the tensile force. The bolt 90 bears a tensile force and can resist the axial force N.

  In addition, when the bending moment M acts on the joint J3, the wedge surfaces 36AH and 38AH are pressed against the fitting member 40, and the bending moment M can be resisted.

For example, as shown in FIG. 4C, the fitting member 40 need not have a bolt hole. In this case, a plurality of bolts 90 are embedded along the axial direction of the first wood 36 and the second wood 38. By doing in this way, the strength reduction of the fitting member 40 can be suppressed. Further, by increasing the number of bolts 90, the bonding strength between the first wood 36 and the second wood 38 can be increased.
