PROBLEM TO BE SOLVED: To provide an inner peripheral structure for a vehicle wheel house, which makes it possible to prevent pebbles and the like lifted upward by a tire from repeatedly hitting the inner peripheral surface of a wheel house or the like and hence reduce hitting sound of pebbles.SOLUTION: The inner peripheral surface structure comprises: an external inclined surface 11 covering a tread surface 21 of a tire 20 and oriented obliquely outside in a vehicle width direction of a vehicle 1; an internal inclined surface 12 continuously formed from an end part of the external inclined surface 11 inside in the vehicle width direction, covering the tread surface 21, and oriented obliquely inside in the vehicle width direction; and a back inclined surface 13 continuously formed from an end part of the internal inclined surface 12 inside in the vehicle width direction and oriented obliquely outside in the vehicle width direction. An intersecting angle AN1 of the internal inclined surface 12 and the back inclined surface 13 is 85 degrees or greater. This makes it possible to prevent pebbles and the like lifted upward by the tire 20 from repeatedly hitting the inner peripheral surface of a wheel house 10 and hence reduce hitting sound of pebbles.SELECTED DRAWING: Figure 2

    【課題】タイヤによって巻き上げられる小石等がホイールハウス等の内周面に繰り返し衝突することを回避して石当たり音を低減することができる車両用ホイールハウスの内周面構造を提供する。【解決手段】タイヤ20のトレッド面21を覆い車両1の車幅方向斜め外側を向く外傾斜面11と、外傾斜面11の車幅方向内側の端部から連続して形成されてトレッド面21を覆い車幅方向斜め内側を向く内傾斜面12と、内傾斜面12の車幅方向内側の端部から連続して形成されて車幅方向斜め外側を向く奥傾斜面13と、を有し、内傾斜面12と奥傾斜面13との交角AN1は、85度以上である。これにより、タイヤ20によって巻き上げられる小石等がホイールハウス10の内周面に繰り返し衝突することを回避して石当たり音を低減することができる。【選択図】図2
