[TASK] In a vehicle side collision, a roof reinforcement member provided between left and right roof side rails is prevented from being bent despite a load acting on a center pillar, and the center pillar is prevented from moving toward the vehicle interior. [MEANS OF SOLVING THE PROBLEM] In an automobile roof structure in which each end 44 of the roof reinforcement member 4 is connected to a roof side rail 2 via a bracket 5, the base end of the bracket 5 is fixed to the end 44 of the roof reinforcement member 4, a base plate 50 of the bracket 5 has upstanding sections 51, 52, 53 that extend to a head edge 54 of the base plate, the upper end of an upstanding end edge 56 of each upstanding section abuts the upper end of a vehicle interior side-surface 21 of the roof side rail 2, a gap is provided between the lower portion of the upstanding end edge 56 and the side surface 21. A rotational moment M that is induced in the roof side rail 2 by a collision load acting from the center pillar 3 is not transmitted to the roof reinforcement member 4.
