PROBLEM TO BE SOLVED: To provide an inner fender for a vehicle capable of reducing air resistance in a wheel house. SOLUTION: The inner fender 10 is installed in the vehicular wheel house and has a plurality of dimples 15 on its surface 11a. When the flow speed of air in the wheel house reaches a prescribed value due to an increase of the vehicle speed, a flow at a boundary layer in proximity to the surface 11a of the inner fender 10 is transitted from a stratified flow to a turbulent by the dimples 15, to cause the peeling position of the boundary layer to shift to further downstream so that the pressure of a low-pressure peeling area likely to be a cause of the air resistance may rise to result in the reduction of the air resistance.
