Patent ID: 7815007

Claim:
A hood impact absorbing apparatus configured such that a rear end of a hood is pushed up at the time of a collision of a vehicle, and when a collision body is battered against a top surface of the hood, descending of the rear end of the hood is permitted so as to mitigate an impact to the collision body, the hood impact absorbing apparatus, comprising: an actuator incorporated into a vehicle main body except for the hood in the vehicle; a push-up rod arranged movably on the actuator, standing by at a standby position below the hood at a normal time, held after being moved to an actuating position above the standby position at the time of a collision of the vehicle and bringing the rear end of the hood into a state of being pushed up to an upper limit position; a first slide contact portion provided on the hood, contacted with a distal end of the push-up rod, slidingly contacting and moving the distal end of the push-up rod and folding a proximal end of the push-up rod while the rear end of the hood descends from the upper limit position, and formed so as to decrease a slide contact angle (θ) that is an angle formed between a first vector oriented to a slide contact movement direction of the distal end of the push-up rod and a second vector oriented from the proximal end of the push-up rod to the distal end as the slide contact movement advances; and a second slide contact portion along which the distal end of the push-up rod having passed through the first slide contact portion slidingly contacts and moves and which is larger in slide contact angle (θ) than a terminal end of the first slide contact portion.
