Molded from resin, this support body 14 has a panel fitting groove 14a located at the center in the width direction and opening on the inner peripheral surface side (lower surface side in the figure).
are formed over the entire lengthwise direction, and two rail mounting grooves are located on both sides in the width direction so as to sandwich the panel fitting groove 14a in the center, and each open to the outer circumferential surface side (upper surface side in the figure). 14b, 14b are formed over the longitudinal direction. The panel fitting groove 14a is relatively wide, substantially the same as the thickness of the balustrade panel 13, and is formed deeply from the inner peripheral surface side to the vicinity of the outer peripheral surface side. It can be fitted, and the rail mounting grooves 14b, 14
b is narrow in width, but is deeply formed from the outer peripheral surface side to approximately the middle from the inner peripheral surface side so as to sandwich the panel fitting groove 14a in the center and overlap in a staggered manner;
The dual leg portions of a guide rail 15, which will be described later, can be fitted therein.

Further, the support body 14 has its panel fitting groove 14.
A, and the rail mounting grooves 14b, 14b, a plurality of screw insertion holes 14c are formed at the same pitch interval so as to correspond to the notches 13a of the balustrade panel 13. Each of the screw insertion holes 14c has stepped large diameter openings 14d at both ends.

The guide rail 15 is made of metal, and has a cylindrical portion 1 that guides the movable handrail 16 on both sides in the width direction.
