Vehicle pop-up hood apparatus

A pop-up hood apparatus includes a hood, a hood lock mechanism, a support mechanism of the hood lock mechanism, and an actuator that displaces the hood lock mechanism upward. The support mechanism includes a movable block that supports the hood lock mechanism and a base block and that supports the movable block such that the movable block is slidable upward and downward. The base block has a long hole that extends along a vertical direction. A protrusion part that is slidably inserted in the long hole is provided on the movable block. A resistance-applying part that comes into contact with the protrusion part and that applies a resistance to the protrusion part is provided in at least a higher region of the long hole than a required elevation position of the hood.
