(Prior art and its problems) Conventionally, when connecting a handrail cap and a plurality of standers, the upper end surface of the stand is cut into a curved shape corresponding to the outer surface of the headboard, which has a circular cross section. While this curved end surface is engaged with the lower surface of the Kasagi, a long through bolt that hangs upward from the inside of the lower horizontal frame or stands upright from the base is inserted into the brace. The upper end of the cap protruded from a bolt hole provided in the cap, and a nut was screwed onto this protruding end from the inside of the cap and tightened, thereby connecting the cap and the stand. Of course, the tightening is done with the upper part of the Kasagi removed.) However, this method required a specially made long through-bolt for each stand, which caused the problem of high construction costs.

(Technical means for solving the problems) The present invention solves the above problems, and the technical means is to solve the above-mentioned problems.
Alternatively, the lower mold member 1b is provided with a concave portion 7 that opens on the upper surface side or the lower surface side over the entire length of the horizontal frame member 1, and a bis pocket 11 is provided inside each brace 4 over the entire length. Insert the end of each brace 4 into the recess 7 of the frame member 1, and insert the tip into the recess 7.
Screw the screw 12 into the screw pocket 11 of the stand 4 from the bottom wall 7a,
Furthermore, a cover member 13 is attached to the recessed part 7, which is formed to cover the opening of the recessed part 7 except for the part where the bar 4 is inserted.
