Abstract:
1. A vehicle pop-up hood apparatus comprising: an arm member, of which a proximal end portion is connectable to a body of a vehicle so as to be pivotable about a first axis extending in a width direction of the vehicle; a first connection part that is connectable to a hood of the vehicle, the first connection part being rotatably connected, by a connection shaft, to a tip side portion of the arm member, so as to allow the hood to pivot relative to the arm member about a second axis extending in the width direction of the vehicle, the second axis being coaxial with the connection shaft; a shear element that serves as a second connection part that connects the first connection part to the arm member to prevent the hood from pivoting relative to the arm member about the second axis; an actuator that generates a lifting force that lifts the hood relative to the body and breaks the connection established by the second connection part; a first restriction mechanism that restricts an angle of pivotal movement of the arm member relative to the body to a predetermined angle at a connection portion at which the proximal end portion of the arm member and the body connect; and a second restriction mechanism that, when the hood is lifted by the lifting force, stops the ascent of the hood before pivotal movement of the arm member is stopped by the first restriction mechanism.
