To provide an upper vehicle body structure etc. which enables reduction of entry of a pillar into a vehicle cabin through displacement suppression of roof side rails during a lateral collision.SOLUTION: An upper vehicle body structure includes: roof side rails 10, each of which has a closed cross section extending in an anteroposterior direction at an outer portion as seen in a vehicle width direction of an upper part of a vehicle; pillars 5, each of which extends downward from a middle part as seen in a vehicle body anteroposterior direction of the roof side rail 10; and roof rail reinforcements 13, each of which extends in the anteroposterior direction at an interior of the middle part as seen in the vehicle body anteroposterior direction, is bent to the outer side in the vehicle width direction at front and rear end parts, and is disposed so as to partition an internal space of the roof side rail 10 in the anteroposterior direction and the vehicle width direction. Each roof side rail has: a roof rail outer 11; and a roof rail inner 12 which cooperates with the roof rail outer to form a closed cross section. Each pillar has: a pillar outer 5a; and a pillar inner 5b which cooperates with the pillar outer to form a closed cross section extending in a vertical direction. Each roof rail reinforcement is fixed to at least the roof rail outer, the roof rail inner 12, and the pillar inner.SELECTED DRAWING: Figure 5

    【課題】側面衝突時におけるルーフサイドレールの変位抑制を介してピラーの車室内への侵入を軽減可能な上部車体構造等を提供すること。【解決手段】車両の上部車幅方向外側部分に、前後方向に延びる閉断面を有するルーフサイドレール10と、その車体前後方向途中部から下方に延びるピラー5と、その車体前後方向途中部の内部で前後に延び且つ前後端部が車幅方向外側に屈曲されてその内部空間を前後方向及び車幅方向に仕切るように配設されたルーフレールレイン13を備えた上部車体構造において、ルーフサイドレールは、ルーフレールアウタ11と、このルーフレールアウタと協働して閉断面を形成するルーフレールインナ12を有し、ピラーは、ピラーアウタ5aと、このピラーアウタと協働して上下方向に延びる閉断面を形成するピラーインナ5bを有し、ルーフレールレインは少なくともルーフレールアウタとルーフレールインナ12とピラーインナに固定される。【選択図】図5
