PROBLEM TO BE SOLVED: To provide a roof side reinforcement structure of a curtain airbag-mounted vehicle which can obtain sufficient reinforcement effect with a simple configuration.SOLUTION: An extension auxiliary member (8) for regulating an extension direction of an air bag (2, 21) includes: a base end stationery part (83) which is fixed to a rail side panel (41); a first extension auxiliary surface (81) which is oriented diagonally downwards on a lower side of the air bag toward a cabin from the base end stationery part; a second extension auxiliary surface (82) which is oriented diagonally upwards on an upper side of the air bag toward the cabin; and an upper end stationery part (84) which is fixed to a roof cross member (31) at an upper end of the second extension auxiliary surface. The second extension auxiliary surface serves as also a brace (82) which linearly extends over a flange stationery part (34) between the base end stationery part (83) and the upper end stationery part (84), and an inflator (22) for expanding and extending the air bag (21) is located on a vehicle longitudinal direction rear side or front side of the extension auxiliary member (8).SELECTED DRAWING: Figure 3
