  "textContent": "In a vehicle pop-up hood device, a piston rod (70) can be raised to a retention position on the vehicle upper side of a lock position. Furthermore, the piston rod (70) raised to the retention position is temporarily retained by a lock mechanism (80). Additionally, when, during oscillation of a hood that occurs after the hood has been pushed up by an actuator (50), the vehicle width direction central portion of the hood becomes displaced from top dead center toward the vehicle lower side and reaches bottom dead center or near bottom dead center, the state in which the piston rod (70) is temporarily retained by the lock mechanism (80) becomes cancelled and both vehicle width direction end portions of the hood become displaced to the lock position. Because of this, strain in the hood is eliminated at the point in time when the oscillation speed of the hood becomes substantially zero, and the hood becomes substantially horizontal. As a result, the amplitude of the hood in the lock position is reduced, so the oscillation that has occurred in the hood can be damped at an early stage.",
