。On the outer periphery of the vertical support cylinder 4 below the first turning protrusion 16,
A first protrusion 17.18 in the left and right direction is formed by changing the phase by 90'' from the above-mentioned retaining protrusion 16. Extracting protrusion 17.1
8 is inserted into the engagement groove 6.7 from above and then inserted into the vertical support cylinder 4.
When it is rotated in the A direction, its L end comes into contact with the lower end of the bent portion 9.9, preventing the vertical support tube 4 from being pulled out.

。Since the present invention has the above-mentioned configuration, the engagement yt6.7 is formed on the upper plate 3 of the bracket 2, so the upper plate 3
Insert the lower end of the vertical support tube 4 into the L portion insertion hole 5 of the vertical support tube 4.
When inserting from the side with the first protrusions 17 and 18 of the vertical support tube 4 facing left and right, the protrusions 17 and 18 of the vertical support cylinder 4
! 8 engages in the engagement groove 6.7 of the upper plate 3. Therefore, the lower end of the vertical support cylinder 4 is connected to the lifting protrusion 17 of the vertical support cylinder 4.
．． 18 is engaged with the engagement groove 6.7 of the upper plate 3, so that it is guided and inserted into the lower insertion hole 11 of the lower plate.

に当接しく第２図、第６図）。Further, when the vertical support cylinder 4 is pushed downward, a rotation first protrusion 16 is formed on the lower surface of the locking device 13 of the vertical support 04.
2 and 6), so that the lower end of the rotation projection 16 comes into contact with the upper surface of the upper plate 3 (Figs. 2 and 6).
縦支持筒４がそれ以上下らなくなる。The vertical support tube 4 will no longer go down.
この状態で、縦支持筒４を矢印イ方向に回転させると、

２の円弧面側に当接する。In this state, when the vertical support cylinder 4 is rotated in the direction of arrow A,
■The bent portion 9.9 of the one plate 3 is formed with an inclined surface 10.10 that protrudes downward in the direction of rotation of the vertical support tube 4. 17 and 1
The L surface of the toe projection 18 is in contact with the inclined surface 10.10, and when the vertical support cylinder 4 is further rotated, the upper surfaces of the ejection W and ejection tooth projections 17 and 18 are guided to the inclined surface 10.10. The vertical support tube 4 is lowered (Fig. 4, Fig. 9), and the +h protrusion 1 is removed.
The inclined surface 19 of 7 abuts against the arcuate surface side of the bracket 2 on the side of the skeleton frame 1.

取付けが終了する。On the other hand, an elastic piece 8 is formed on the upper plate 3 on the front side of the engagement groove 7 to lower the rotating protrusion 16 on the lower surface of the locking device 13 of the vertical support cylinder 4. Then, as the vertical support tube 4 is lowered, the rotation first protrusion 16 moves while pushing down the gripper 8 and engages with the engagement groove 7, thereby completing the installation of the vertical support tube 4.
この場合、前記弾性片８は弾性を有してＬ下するから、

When the first rotation protrusion 16 engages with the engagement groove 7, it moves 1-
To prevent rotation of the vertical support cylinder 4. Since the upper surfaces of the first and second protrusions 17 and 18 are in contact with the lower end of each bent portion 9, the vertical support cylinder 4 is prevented from coming off, and the first and second protrusions are prevented from coming off. Since the inclined surface 19 of 17 is in contact with the circular arc surface on which the bracket 2 is attached to the skeleton frame 1, it is possible to prevent the vertical support tube 4 from falling.
