It is composed of a cap 54. That is, the plate material 52 has an exposed portion 52a that is flush with the outer surface of the channel material 53, a bent portion 52b extending from both side edges of the exposed portion 52a toward the support column 3, and a bent portion 52b extending from the tip of the bent portion 52b. It consists of an extending portion 52c extending parallel to the exposed portion 52a,
A guide rail 52d in the form of a protrusion is integrally provided on the outer surface of both bent portions 52b. and,
A bolt hole 55 is provided at the lower end of the extending portion 52c, and a female threaded portion 39 is provided at a portion of the mounting bracket 33, which is a fixed portion of the column 3, corresponding to each of the bolt holes 55 to secure the plate material. The plate material 52 is fixed to the support column 3 by passing a screw member 51 through the bolt hole 55 and screwing it into the female threaded portion 39. On the other hand, the channel material 53 has a C-shaped cross section and has grooves 53a extending vertically on both opening edges thereof, and by engaging the grooves 53a with the guide rail 52d, the plate material 52 It is connected so that it can slide vertically.
