PROBLEM TO BE SOLVED: To provide a center pillar structure capable of being easily manufactured and increasing deformation yield strength relative to side surface collision load without excessively increasing weight. SOLUTION: The structure of the center pillar structure 1 for an automobile is provided with an outer frame member 4; an inner frame member 5; and a reinforcement frame member 6 arranged between the outer frame member 4 and the inner frame member 5. The reinforcement frame member 6 has a projection part 60c bent/formed on a vertical cross section in a longitudinal direction so as to be projected toward a side of the inner frame member 5 in an intermediate part in a vehicle longitudinal direction; and an end reinforcement wall part 62a extending toward the inner frame member 5 along the outer frame member 4 at both ends in the vehicle longitudinal direction. Further, the reinforcement frame member 6 is fixed to the outer frame member 4. COPYRIGHT: (C)2009,JPO&INPIT
