To provide a vehicle body roof reinforcement structure configured to increase snowfall intensity of a roof outer panel of a vehicle body.SOLUTION: A vehicle body roof reinforcement structure 1 includes a substantially rectangular-shaped roof outer panel 9 supported by an A-pillar 3, a B-pillar 5, and a C-pillar 7. In a vehicle body on which the roof outer panel is configured such that a ratio of a length in a vehicle body width direction to a length in a vehicle body longitudinal direction is 1.6 or lower, a band-shaped reinforcement member 15 of resin is attached to a lower surface of the roof outer panel and thereby snowfall intensity is increased. The band-shaped reinforcement member includes a front side portion 17 extending along a front side 9a of the roof outer panel between opposite sides 9c of the roof outer panel and a rear side portion 19 extending along a rear side 9b of the roof outer panel between the opposite sides 9c, bent portions 21 arranged at respective corner portions 9d of the roof outer panel and having intermediate portions each bent inward of the outer panel in a protruded shape, and extending portions 23 extending from the respective bent portions toward the corner portions.SELECTED DRAWING: Figure 1

    【課題】車体のルーフアウタパネルの積雪強度を向上させる車体ルーフ補強構造。【解決手段】車体ルーフ補強構造1は、Aピラー3、Bピラー5およびCピラー7によって支持される略矩形状のルーフアウタパネル9を有し、該ルーフアウタパネルにおける車体長さ方向と車体幅方向の長さの比が1.6以下である車体において、前記ルーフアウタパネルの下面に樹脂製の帯状補強部材15を貼付することにより積雪強度を向上させるものであって、前記帯状補強部材は、前記ルーフアウタパネルにおける前辺9aおよび後辺9bのそれぞれに沿って前記ルーフアウタパネルの両側辺9cまで延在する前辺部17および後辺部19と、前記ルーフアウタパネルの各コーナー部9dに配置され、中央部が前記アウタパネルの内側に向かって凸状に屈曲する屈曲部21と、各屈曲部から前記各コーナー部に向かって延在するコーナー延在部23と、を備えてなることを特徴とする。【選択図】図1
