PURPOSE: To prevent a fixing member between the first and the second members from being exposed on the surface by a constitution wherein a female member is provided in the first member to hold a flight member and an assembly of a washer and a nut in an enlarged hole of the second member is connected with this flight member. CONSTITUTION: A non-exposed device 300 contains a copper inserting part 302 inserted into a receiving hole 102 of a leg member 100 and the inserting part 302 is surely held by means of a spiral wood flight 303 in the leg member 100. A screw-cut bar 304 is screwed into the inserting part 302 with tapped inside. The bar 304 is inserted into the member 200 through a hole 206 made in the longer direction so as to facilitate the end part of the bar 304 enter into a nut and a washer 310 connected in an enlarged hole 208 made on the inside of the member 200 in the side face direction. When the washer and the nut are tightly connected with the bar 304, the second member 200 is precisely connected with the leg member 100 by applying an equal pressure to both rivets 202 and 204 and is held.
