PROBLEM TO BE SOLVED: To provide a fiber-reinforced resin-made center pillar structure which can obtain a desired impact absorption load by properly axially collapsing an energy absorption member which is arranged in a center pillar at a side face collision.SOLUTION: A center pillar structure comprises: an energy absorption member for absorbing a collision load by being axially collapsed at a side face collision; a reinforcing member arranged at an inner face of an outer member; and a transmission member having a fixed part fixed to the reinforcing member, and a pressing part which is arranged at an upper part than the fixed part while separating from the inner face of the outer member and the reinforcing member, and transmits the collision load to the energy absorption member, and having at least higher rigidity than those of the outer member and an inner member. The fixed part of the transmission member is located at a position opposing an opening part of the inner member, and the energy absorption member is supported while separating from the inner member or the pressing part before the side face collision, and at the side face collision, sandwiched by an inner face of the inner member and the pressing part in an upper part of the opening part, and collapsed.SELECTED DRAWING: Figure 5
【課題】側面衝突時に、センターピラーの内部に配置されたエネルギ吸収部材を適切に軸圧壊させて、所望の衝撃吸収荷重を実現可能な繊維強化樹脂製のセンターピラー構造を提供する。【解決手段】センターピラー構造は、側面衝突時に軸圧壊して衝突荷重を吸収するエネルギ吸収部材と、アウタ部材の内面に設けられた補強部材と、補強部材に固定される固定部、及び、アウタ部材の内面及び補強部材から離間して固定部よりも上方に配置されてエネルギ吸収部材に衝突荷重を伝達する押圧部を有し、少なくともアウタ部材及びインナ部材よりも高い強度を有する伝達部材と、を備え、伝達部材の固定部がインナ部材の開口部に対向する位置にあり、エネルギ吸収部材は、側面衝突前にはインナ部材又は押圧部から離間して支持され、側面衝突時には開口部の上方でインナ部材の内面と押圧部とにより挟まれて圧壊される。【選択図】図5
