PROBLEM TO BE SOLVED: To maintain a strong fastening force between both wooden members after long years, without being affected by a wood contraction in a width direction at a connecting part of wooden members. SOLUTION: In a connecting part of two wooden members 20 and 20 to be placed to have an angle between them, two anchor members 11 and 11 are embedded in holes drilled on a center line of both wooden members. Each rod is inserted from side holes set from a side of both wood members in a diagonal direction and each of rods 12 and 12 is screwed into screw holes 11 and 11 set at each side part of the anchor members. These two rods 12 and 12 are placed on almost the same line to introduce a pulling force to each rod 12 by connecting other edge together through a turnbuckle 13. When two wooden members are fast fastened by this pulling force, as the anchor members are placed on the center line of wood members, a strong fastening force is maintained without being affected by a wood contraction in the width direction.
