A hood lift apparatus of a vehicle is provided to absorb shock efficiently by lifting up a hood in bumping a pedestrian into the hood, to open and close the hood conveniently by functioning as a hood hinge, and to reduce manufacturing cost and weight of the vehicle by simplifying structure. A hood lift apparatus of a vehicle includes a plunger(5) combined with a lower part of a hood(1) by a hinge and provided with a piston(3), a cylinder(7) guiding linear motion of the piston of the plunger and moving up and down the piston to a vehicle body, and a gas generator formed in a lower part of the cylinder. The cylinder is fastened in the vehicle body by a mounting bracket(15), and a vent hole(17) is formed in the cylinder to slowly discharge expansion gas from the gas generator out of the cylinder. Shock is gradually absorbed in bumping a pedestrian into the hood by moving down the plunger with discharging gas from the cylinder through the vent hole. |
