Zusammenfassung:	To efficiently cool a site of an oil pan at the rear of a vehicle with traveling wind.SOLUTION: An oil pan 2, which is arranged below the engine of a motorcycle and stores engine oil, comprises: a shallow bottom part 3; and a deep bottom portion 4 formed so as to extend in a vehicle front-rear direction substantially at the center of the shallow bottom part in a vehicle left-right direction, and formed deeper than the shallow bottom part, wherein the space in the vehicle left-right direction at both side walls of the deep bottom part facing the vehicle left-right direction is formed so as to increase from the front of the vehicle to the rear of the vehicle.SELECTED DRAWING: Figure 6 【課題】オイルパンの車両後方の部位を走行風により効率的に冷却する。【解決手段】二輪車のエンジン下部に配置され、エンジンオイルを貯留するためのオイルパン２は、浅底部３と、前記浅底部の車両左右方向略中央において車両前後方向へ延びるように、かつ前記浅底部よりも深く形成された深底部４であって、車両左右方向に対向する前記深底部の両側壁部における車両左右方向の間隔が、車両前方から車両後方へ向かうにつれて大きくなるように形成されている深底部とを備えている。【選択図】図６
