Reference numeral 17 denotes a pipe-shaped table leg having a hollow portion 18 and a small hole 18 'and having a thick portion.

To assemble each member formed as described above, the following is performed.

The head 3 of the core rod member b is welded at right angles to the back surface of the leg mounting plate 1. Then, the leg fixing member c is fitted so as to embrace the whole core rod member b, and the pressure plate d fitted in the window 13 of the fixing member c is opposed to the notch 4 of the core rod member b, The small holes 14 of the pressure plate d are aligned with the small holes 7 of the core rod member b, and the socket bolt 16 is screwed. Among the above constituent members, the core rod member excluding the leg mounting plate 1, the leg fixing member fitted so as to embrace the entire core rod member, and the pressure fitted into a window hole of the leg fixing member. A plate and a socket bolt are fitted into the hollow portion 18 of the pipe-shaped table leg 17,
By inserting a screwdriver into the socket portion 16 ′ of the bolt 16 from the small hole 18 ′ of the table leg 17 and rotating, and pulling the pressure plate d inward,
Outer side portions near the notch portion 4 of the core rod member b constitute leg fixing members c. Left and right side wall portions 9 and 10 are developed in directions opposite to the small holes of the pipe-shaped table legs, and the corner portions 8 and Pressing part
11 and 12 press against the inner surface of the thick part of the pipe-shaped table leg 17 and firmly adhere to it.

Note that the window portion 13 of the leg fixing member c is slightly enlarged,
Alternatively, by slightly increasing the size of the small hole 18 'of the table leg 17, the height of the table leg 17 can be appropriately adjusted and fixed.

[Effect] According to the present invention, when a screwdriver is inserted into the socket portion of the socket bolt screwed into the small hole of the core rod member and turned, the pressure plate and the core rod inserted into the window portion are rotated. Since the notch portion of the member is formed in a flat shape, the both side walls of the leg fixing member are uniformly adhered in a direction opposite to the small holes of the pipe-shaped table leg with uniform pressing force and uniform pressing force. Since the corners and both pressing portions forming the fixing member also strongly press the inner surface of the thick portion forming the pipe-shaped table leg with a uniform pressing force, This has the advantage that the table legs can be securely fixed.
