Summary:PROBLEM TO BE SOLVED: To provide a deflector of a vehicle capable of reducing negative pressure at a rear end of a baffle plate portion, while allowing the baffle plate portion to have high rigidity and strength.SOLUTION: There is provided a deflector of a vehicle disposed on a top face of a bonnet 3 of a vehicle, and having: a baffle plate portion 13 inclined so as to be spaced apart from the bonnet as going backward of the vehicle; and an air duct opening 21 provided at the baffle plate portion, for guiding a part of aerodynamic drag to a back surface side of the baffle plate portion. At an opening edge of the air duct opening, there is formed a duct portion for guiding aerodynamic drag allowed to flow in from the air duct opening, to a part right under a rear end, in a vehicle longitudinal direction, of the baffle plate portion. This structure causes aerodynamic drag α flowing in from the air duct opening of the baffle plate portion to be guided to the part right under the rear end of the baffle plate portion where negative pressure is generated, while diffusion of the drag is prevented by the duct portion, thus reducing pressure difference between both surface sides at the rear end of the baffle plate portion. In addition, surface rigidity of the baffle plate portion is supplemented with rigidity of the duct portion, thus the baffle plate portion is enabled to have high rigidity and strength.SELECTED DRAWING: Figure 2 【課題】本発明は、導風板部の剛性強度を確保しつつ、導風板部後端における負圧の発生を抑制することができる車両のデフレクタを提供する。【解決手段】本発明は、車両のボンネット3の上面に配置され、車両後方に向かうにしたがいボンネットから離れる方向に傾斜した導風板部13と、前記導風板部に設けられ、走行風の一部を導風板部の裏面側に導く導風開口21とを有する車両のデフレクタであって、導風開口の開口縁には、導風開口から流入された走行風を前記導風板部の車両後方向端の直下へ導くダクト部が形成されるものとした。これにより、導風板部の導風開口から流入する走行風αは、ダクト部により、拡散が抑えられながら、負圧が発生している導風板部後端の直下へ導かれ、導風板部の後端両側での圧力差は改善される。しかも、導風板部の面剛性はダクト部の剛性で補われるから、導風板部の剛性強度は確保される。【選択図】図2
