Patent number: 9637185Abstract: In a vehicle to which a wheel well rear portion structure has been applied, a curved portion of an upper wall of a guide portion bulges obliquely toward the vehicle lower side as seen in a side view and is connected to a discharge portion. An air flow flowing in a flow channel flows along the upper wall due to the Coanda effect, so in the air flow along the curved portion the flow component heading toward the vehicle rear side becomes larger. The flow direction of the air flow discharged from the discharge portion substantially coincides with the flow direction of an air flow flowing in the space under the body of the vehicle. In a state in which a drop in the flow speed of the air flow discharged from the discharge portion is controlled, the air flow can be caused to smoothly merge with the air flow.Type: GrantFiled: March 5, 2014Date of Patent: May 2, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Fumihiko Kishima, Kazuya Koizumi

Patent number: 9381956Abstract: In a vehicle to which a vehicle body front structure is applied, an opening portion is formed behind a rear end portion of an arch portion. The opening portion is held in communication with an air flow passage, and is opened backward with respect to the vehicle. Then, the air caused to flow into the air flow passage during traveling of the vehicle flows from a front side toward a rear side with respect to the vehicle, and is discharged from the opening portion backward with respect to the vehicle. Thus, the air current blown out from the air flow passage to an outside of the wheel house in a vehicle width direction via the wheel house is restrained from being produced. Therefore, the traveling wind flowing outside the wheel house in the vehicle width direction is restrained from hitting the air current.Type: GrantFiled: August 26, 2013Date of Patent: July 5, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Fumihiko Kishima, Kazuhiro Maeda, Kazuya Koizumi, Taro Yamashita
