PURPOSE: A connecting structure for a roof corner portion of a bus with a window pillar is provided to improve rigidity of the corner portion of the bus roof by connecting a curved upper end of the window pillar to a lower end of a roof stringer, and a curved lower end of a roof beam to a folding portion of the window pillar portion. CONSTITUTION: A window pillar(10) is formed as a square steel pipe. A folding portion is formed to an upper portion of the window pillar by a bending work. An upper surface of the window pillar is welded to a lower surface of a roof beam(20). A cant rail(40) mounted to a vehicle body longitudinally is connected to both sides of the window pillar. The roof beam is formed as the square steel pipe and mounted to a roof of a bus longitudinally. A curved portion is formed to an end of the roof beam in the shape of a semi-arc. A lower end of the roof beam is welded to the folding portion of the window pillar. A roof stringer(30) mounted to the vehicle body longitudinally is welded to both sides of the roof beam. The curved portion of the roof beam is connected to an upper portion of the cant rail that is not connected with the roof beam and the window pillar. Thereby, bending rigidity and vibration property are improved by connecting the roof beam and the window pillar to the roof stringer and the folding portion of the window pillar after bending.
