Description

Vehicle with a vehicle body having a vehicle body support Technical Field The present invention relates to a vehicle. Background Conventionally, there is known a technique of inclining a rear portion of a vehicle downward toward a rear in a vehicle front-rear direction to improve aerodynamic characteristics. In connection with this, for example, patent document 1 below discloses a rear structure of a vehicle, which is characterized by having a recess extending in the vehicle front-rear direction across the roof top surface, the tailgate upper surface, and the spoiler upper surface at the vehicle width direction center portion. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2010-30465 Disclosure of Invention Technical problem to be solved by the invention However, in the rear structure of the vehicle disclosed in patent document 1, since the recess has a quadrangular shape as viewed from the vehicle up-down direction, when the length of the recess in the vehicle front-rear direction is increased for the purpose of improving aerodynamic performance, the front end of the recess protrudes above the head of the occupant on the left and right of the rear seat, thereby narrowing the head space. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a vehicle capable of improving aerodynamic performance while suppressing a head space of a passenger on the left and right of a rear seat from being narrowed. Technical scheme for solving technical problems The vehicle according to the present invention for achieving the above object has a recess extending in the vehicle front-rear direction from the upper surface of the roof portion to the upper surface of the rear spoiler in the vehicle width direction center portion, the recess having a first apex disposed in front of the vehicle and two second and third apices disposed in rear of the vehicle.
