Thereby, the angle change of the knee becomes large, and there is a concern that the load on the knee increases. Therefore, in the conventional vehicle body front structure, there is a storage position that covers the vehicle front of the bumper reinforcement and an operation position that is disposed below the storage position and protrudes forward of the vehicle from the bumper reinforcement. Some have a movable bumper (see, for example, Patent Document 1).
