1. A carrier bar comprising: a shell formed along a longitudinal direction; and hollow zones formed in a cross-sectional structure, the carrier bar being assembled with a stay by using a clamp mechanism having a head and a constricted portion to form a base carrier, wherein the shell has an assembly opening and a positioning opening, the positioning opening extends toward a longitudinal end or a longitudinal center of the shell by using the assembly opening as a basal end, a terminated end of the positioning opening is formed by the longitudinal end of the shell when the positioning opening extends toward the longitudinal end, the terminated end of the positioning opening is formed by the longitudinal center of the shell when the positioning opening extends toward the longitudinal center of the shell, the assembly opening has an opening width and an opening length into which the head of the clamp mechanism is insertable, and the positioning opening has an opening width, narrower than that of the assembly opening, along which the constricted portion is slidable, and an opening length longer than that of the assembly opening, the carrier bar further has a lid that seals a part of the assembly opening and the positioning opening after the carrier bar is installed to the stay, the lid is arranged to extend from an opening end of the assembly opening that does not communicate with the positioning opening toward a side of a hollow portion that does not seal the assembly opening in the longitudinal direction of the shell, and the lid is slidable to seal the assembly opening and the positioning opening.
