Abstract: A sun shade apparatus is provided. Each of a pair of right and left roof side rails is constituted of upper and lower members which are joined to each other. A dimension in an up-down direction can be reduced while a closed cross-sectional area required for the roof side rail is ensured to maintain a strength and a rigidity thereof, and a height of a vehicle cabin can be ensured by compactly disposing a sun shade apparatus under a lower surface of a roof panel while enhancing side collision resisting performance by restricting bending of the roof side rails in cooperation with a cross member when a collision load of a side collision is input. Due to roof side garnishes covering outer end portions of the roof panel and upper surfaces of the roof side rails, the rigidity and the strength of the roof side rails can be further enhanced.
