An intake passage structure for a vehicle is provided with: a hollow intake air intake part (33) having an intake opening and communicating with an intake passage main body; and an intake air guide member (40) provided in the intake air intake part, the intake air guide member (40) being provided with: a first guide part (41) disposed on the intake air upstream side and having a first upper surface part protruding from the intake opening part to the inner part of the intake air intake part, a first side surface part (41b), and a first front surface part (41c) disposed in the inner part of the intake air intake part; and a second guide portion (42) disposed on the intake downstream side of the first guide portion (41) and having a second upper surface portion protruding from the intake opening toward the inner portion of the intake air intake portion, a second side surface portion (42b), and a second front surface portion (42c) disposed on the inner portion of the intake air intake portion, the first guide portion (41) having a larger amount of protrusion toward the inner portion than the second guide portion (42), and the second guide portion (42) having a larger amount of protrusion toward the inner portion than the second guide portion (42). The curvature of the curved surface of a first corner portion (41g) where the first side surface portion (41b) and the first front surface portion (41c) are continuous is smaller than that of a second corner portion (42g) where the second side surface portion (42b) and the second front surface portion (42c) are continuous.

    一种车辆用进气通道构造,具备:中空的进气取入部(33),具有进气开口部,并供进气通道主体连通连接;和进气引导构件(40),装备于进气取入部内,进气引导构件(40)具备:第1引导部(41),配置于进气上游侧,并具有从进气开口部向进气取入部内的里部突出的第1上表面部、第1侧面部(41b)、以及配置于进气取入部内的里部的第1正面部(41c);和第2引导部(42),配置于第1引导部(41)的进气下游侧,并具有从进气开口部向进气取入部内的里部突出的第2上表面部、第2侧面部(42b)、以及配置于进气取入部内的里部的第2正面部(42c),第1引导部(41)与第2引导部(42)相比向里部的突出量大,使第1侧面部(41b)与第1正面部(41c)连续的第1角部(41g)与使第2侧面部(42b)与第2正面部(42c)连续的第2角部(42g)相比,曲面的曲率小。
