Zusammenfassung:	PROBLEM TO BE SOLVED: To connect lumbers simply, easily, and securely through a dowel and a tenon so as to prevent them from coming off. SOLUTION: In this lumber connection structure, both ends of a wooden dowel 2 are fitted into a connection hole 3 of lumbers 1 to be connected mutually to connect the lumbers 1 through the dowel 2. Furthermore, the dowel 2 is formed into an outer shape fitted into the connection hole 3 by shrinking the lumber 1 from outer periphery toward the center thereof to put it in a condition in which it is thin and shrunk. The compressed wooden dowel 2 is inflated by absorbing adhesive 6 like liquid or paste in a condition in which it is put in the connection hole 3 and adheres closely on an inner face of the connection hole 3 without causing a clearance to connect the lumbers 1 through the adhesive 6.
