ABSTRACT:
The present invention provides a hood impact absorbing apparatus capable of further mitigating an impact that a collision body receives from a hood than ever, wherein a push-up rod pushes up the rear end of a hood at the time of a collision of a vehicle, and when a collision body is battered against the top surface of the hood in this state, the rear end of the hood descends and the distal end of the push-up rod slidingly contacts and moves a rear-side flat portion and an arm intermediate curved portion in the rear end of the hood, and herein, a slide contact angle (θ) in the arm intermediate curved portion is larger than a slide contact angle (θ) in the rear end of the rear-side flat portion, thereby, during a process in which the rear end of the hood descends, peaks at which an absorbing amount of impact energy becomes large can be provided at least twice, and as a result, the impact can be mitigated further than ever.
