The T-groove 11 is formed at the same time as the cylinder body 1 is extruded, and has the same cross section in the longitudinal direction. That is, the T groove 11
Consists of an inlet groove 14 and a deeper groove 15 wider than the inlet groove 14,
When the cylinder body 1 is formed by extrusion molding, it is formed at the same time, so that the same cross section is continuous in the longitudinal direction.

Here, the groove width of the inlet groove 14 of the T groove 11 is A, and the groove width of the inner groove 15 is B. As shown in FIGS. 4 and 5, the nut plate 16 has a rectangular shape with a predetermined thickness, and a plurality (two in the illustrated example) of screwing mounting bolts 17 for fixing the auxiliary mounting legs 12. A screw hole 18 is engraved. Assuming that the width of the nut plate 16 is C, the width C of the nut plate 16 is T
The nut plate 16 is formed to be slightly smaller than the groove width B of the inlet groove 14 so that the nut plate 16 can be inserted into the T groove 11 from the side and can be mounted in the inner groove 15, or the width C of the nut plate 16 is set to the inlet groove. 14 is slightly larger than the groove width B, and as shown in FIG.
The nut plate 16 is formed so that the nut plate 16 can pass through the inlet groove 14 and be mounted in the inner groove 15 by making the nut 16 be slanted.

As shown in FIG. 4, since the width C of the nut plate 16 is smaller than the width B of the deep groove 15 of the T-slot 11, the nut plate 16 is located inside the deep groove 15 as shown in FIG. Although the nut plate 16 can move in the vertical direction, when the diagonal end of the nut plate 16 is brought into contact with the diagonal angle θ in the inner groove 15 as shown in the drawing, the screw hole 18 is formed so that the mounting bolt 17 can be screwed. It is set so that it can be seen from the groove 14 side.
