Claims

[Scope of Claim for Utility Model Registration] (1) Consisting of a vehicle, a vibration generator mounted on the chassis of the vehicle, and a house mounted on the vibration generator and accommodating a simulated experience person, the vibration generator A vibration generating device that allows the user to experience an earthquake by generating vibrations in the front-rear direction, left-right direction, and vertical direction in a house, wherein the vibration generator includes a first vibration generator and a first vibration generator that generate mutually different amplitudes and frequencies. Two vibration generators are arranged in a vertical relationship with each other, and the amplitude and frequency generated by the first vibration generator and the second vibration generator are synthesized so that a simulated experiencer in the house can experience an earthquake. Either the first vibration generator or the second vibration generator is configured by a hydraulic oscillation cylinder and a hydraulic oscillator that generates an alternating hydraulic pressure in the hydraulic oscillation cylinder. Earthquake generator. (2) The first vibration generator is equipped with a mechanism that vibrates the house in the front-rear and vertical directions, and the second vibration generator is equipped with a mechanism that vibrates the floor of the house in the front-rear, left-right, and vertical directions. The seismic vehicle according to claim 1, characterized in that:
