PROBLEM TO BE SOLVED: To provide a coupling device for wood members that can connect two wood members rigidly.SOLUTION: In a coupling device for wood members, a screw having a head part is fixed to one wood member, and a connector tool molded by synthetic resin formed with a round hole into which the head part of the screw can be inserted and an oblong hole with a diameter narrower than that of the round hole continuous to this round hole is fitted into a recess part formed at the other wood member. The other wood member is slid under a state in which the head part of the screw fixed to one wood member is fitted to the round hole of the connector member, a side wall part of the oblong hole is pushed wide by the head part of the screw to expand the connector tool, the connector tool is closely contacted with a side wall of the recess part to connect these two members.SELECTED DRAWING: Figure 3 |
