To provide a vehicle body front part structure that can provide quietness in a vehicle cabin and reduce the weight of a vehicle body in a compatible manner.SOLUTION: A vehicle body front part structure includes: a cowl top panel extending at a vehicle cabin front part of a vehicle in a vehicle width direction and supporting a front window; and a dash panel having an upper end portion connected to the cowl top panel and extending in a vehicle up-down direction and the vehicle width direction to define the vehicle cabin front part. A boundary portion having a thickness varying in a vehicle front-back direction is disposed to extending in the vehicle width direction in a region on a vehicle front side of a connection portion to which the dash panel of the cowl top panel is connected. The cowl top panel is formed such that a portion from the boundary portion to a vehicle back side is thinner over a predetermined area from the boundary portion than a portion at a vehicle front side.SELECTED DRAWING: Figure 3
【課題】車室内の静粛性と車体の軽量化の両立を図ることができる車体前部構造を提供する。【解決手段】車体前部構造は、車両の車室前部において車幅方向に延在され、フロントウインドを支持するカウルトップパネルと、前記カウルトップパネルに上端部が接続されるとともに、車両上下方および車幅方向に延在されて車室前部を区画するダッシュパネルと、を備えた車体前部構造であって、前記カウルトップパネルの前記ダッシュパネルが接続される接続部よりも車両前方側の領域に、車両前後で板厚が変化する境界部が車幅方向に亘って設けられ、前記カウルトップパネルは、前記境界部を境に車両後方側の部位が前記境界部から所定範囲にわたって、車両前方側の部位より板厚が薄く形成されている。【選択図】 図3
