PROBLEM TO BE SOLVED: To provide a link for wooden building members, which has a tenon thereof stored in a round mortice formed in a column, and is produceable by press working. SOLUTION: The link R for the wooden building members is formed of the cup-shaped tenon 4 which is inserted into the mortice 6 formed in a main erect member 1, and two mutually opposed flat connection pieces 5 which are inserted into right and left engaging grooves 7 formed in an end face of a joining member 2 to be abutted on the main erect member, and set up such that the connection pieces are protruded from right and left sides of a mouth of the tenon, and fixed to the joining member by fixtures 3. The connector whose right and left connection pieces are protruded from the tenon, is formed of a single metallic plate by press working. Specifically the tenon is a continuous one-piece cup, and the cup is formed such that flat surfaces 8 that define sectional semi-lunar gaps 24 with respect to the round mortice, are continuously formed on right and left side in a protruding direction of the connection pieces 5, and that curved surfaces 14 having an arched cross section along an internal peripheral surface of the round mortice 6 are formed in remaining areas other than the right and left sides.
