In a vehicle (10) to which awheel well rear portion structure (S1) has been applied, a curved portion (44) of an upper wall (40) of a guide portion (30) bulges obliquely forward toward the vehicle lower side as seen in a side view and is connected to a discharge portion (34). Additionally, an air flow (F1) flowing in a flow channel (36) flows along the upper wall (40) due to the Coanda effect, so in the air flow (F1) flowing along the curved portion (44) the flow component heading toward the vehicle rear side becomes larger. For this reason, the flow direction of the air flow (F1) discharged from the discharge portion (34) substantially coincides with the flow direction of an air flow (F2) flowing in the space under the body of the vehicle (10). Because of this, in a state in which a drop in the flow speed of the air flow (F1) discharged from the discharge portion (34) is controlled, the air flow (F1) can be caused to smoothly merge with the air flow (F2). |
