PROBLEM TO BE SOLVED: To enhance reliability by reducing sensors which may cause trouble, and to make a control device inexpensive by simplifying the control. SOLUTION: This base isolation device reduces vibration of a wheelchair 2 mounted on an automobile. The device is provided with a ball screw type electric base isolation mechanism 6 provided on a floor 1 of the automobile to vertically move the wheelchair 2 and having driving force suitable for weight of the wheelchair 2 and a sitting person, an acceleration sensor 11 for detecting upper and lower acceleration of the wheelchair 2, and a base isolation mechanism control device 12 to impart an acceleration signal from the acceleration sensor 11 as a position command signal to the base isolation mechanism 6 to cancel the vertical movement of the wheelchair 2 according to vertical movement of the floor 1 of the automobile.
