PURPOSE: A roof beam and center pillar-integrated structure of a bus is provided to improve impact energy absorption capacity caused at a center pillar by a broadside collision of the bus, to greatly absorb energy with the square tube-typed center pillar during a bent unit is bent, and accordingly to reduce the degree of strain and disperse impact energy. CONSTITUTION: In a bus formed by combining a side body, a front body(20), a rear body, and a roof(400) in a split-combination method, a roof beam and center pillar-integrated structure of the bus integrates a roof beam(420), which is combined with the rear side of the front body at the front side of the roof, with a center pillar(410) and makes a face(411) combined with the front body in a square tube type.
