CONSTITUTION: A roof rack assembly for a vehicle has a cross rail(120) disposed horizontally on a side rail(110) mounted in the longitudinal direction of a vehicle body to adjust longitudinally the position. Guide grooves(113a,113b) are formed at both lateral sides(112a,112b) of the side rail along the longitudinal direction. The cross rail is supported to a mounting member(130) of which the position is regulated along the guide grooves, and installed on the side rail. The mounting member is composed of a locking unit(139) for locking an inside(114) of the guide groove and a combining unit(133) joined with the cross rail, and supported on both lateral sides having the guide grooves and an upside(111) of the side rail.
