PURPOSE:To secure the rigidity of a bar and decrease a wind cutting sound by forming a bar on a roof in square in sectional view, which is used for placing a load and so arranging the inclinations of this bar that they differ at front and rear with each other. CONSTITUTION:A bar 11 is laid horizontally on a seat 9 above a roof 1. The cross section of this bar is formed in a square shape and a caps 87 are installed on both ends of the bar 11. And the rear face 81 of the bar 11 is so formed that it inclines forward at an angle larger than the inclination of a front face 79. Hereby, since running wind runs backward while being rectified at a front face 79 and a rear face 81 at time of running, the wind cutting sound caused by a carrier 5 above the roof can be decreased. Further since the bar 11 is formed in square in the sectional view, even if a heavy load is placed on the bar 11, the bar is hard to deform and the rigidity of the bar 11 can be secured. |
