In addition, a front end panel is assembled | attached to a vehicle body in a vehicle front end part, and is also called a carrier or a radiator support etc. depending on literature.

  By the way, a front end module including a front end panel, a heat exchanger, and the like is normally disposed between an engine that forms a driving source for driving and a bumper reinforcement on the front end side of the vehicle.

  At this time, since the distance between the engine and the bumper reinforcement is relatively small, the front end module is mounted on the front end of the vehicle so that other parts and the front end module do not interfere with each other and the front end module is damaged. It was difficult to assemble to the side, and it was difficult to reduce the assembly man-hours (assembly time).

  In addition, since the heat exchanger such as a radiator is already assembled in the front end module, its weight is large, and the parts mounted on the front end side of the vehicle such as the front end panel and the heat exchanger are individually assembled in the vehicle. Compared to the above, there is a problem that the assembly workability is poor.

  In view of the above, the present invention firstly provides a new vehicle front end structure different from the conventional one, and secondly, to a vehicle having a front end panel (front end module) in which a heat exchanger is assembled. The purpose is to improve assembly workability.
