PROBLEM TO BE SOLVED: To provide a body front part structure of an automobile 1 in which even if a first reinforcement member 20 is joined to a front surface of a cowl panel 10, welding workability can be secured without impairing NVH performance of the automobile.SOLUTION: In a body front part structure of an automobile 1 in which a first reinforcement member 20 is joined to a cowl panel 10, the cowl panel 10 is formed integrally, in a nearly S shape cross section, of an upper surface part 104, a forward swelling part 105 swelling forward and downward, a rearward swelling part 106 swelling rearward and downward and a lower surface part 107. In the first reinforcement member 20 is provided a member main body 21 in which a nearly U shape cross section whose vehicle-rear side is opened is bent and extended along a front surface of the cowl panel 10. The member main body 21 is formed integrally of: a widened part 211, wide in a vehicle width direction and formed in a nearly U shape cross section, which is extended along the forward swelling part 105 to the lower part of the automobile; and a narrowed part 212 in which the nearly U shape cross section extended from the widened part 211 is gradually narrowed in width toward the lower part of the automobile.SELECTED DRAWING: Figure 2
【課題】カウルパネル10の前面に第1補強部材20を接合した場合であっても、車両のNVH性能を損なうことなく、溶接作業性を確保できる自動車1の前部車体構造を提供することを目的とする。【解決手段】カウルパネル10に第1補強部材20を接合した自動車1の前部車体構造であって、カウルパネル10を、上面部104と、前方下方へ膨出した前方膨出部105と、後方下方へ膨出した後方膨出部106と、下面部107とで断面略S字状に一体形成し、第1補強部材20に、車両後方側が開口した断面略コ字形状をカウルパネル10の前面に沿うように屈曲させて延設した部材本体21を備え、部材本体21を、車幅方向に幅広な断面略コ字形状で、前方膨出部105に沿って車両下方側へ延設した幅広部211と、幅広部211から延設された断面略コ字形状を車両下方ほど幅狭に絞った絞り部212とで一体形成されたことを特徴とする。【選択図】図2
