PURPOSE:To prevent the influence from being transmitted to a superstructure even if a main hull brings about sizable rolling or pitching, by making weight of the superstructure so as to be supported by one buffer capable of almost disregarding a spring constant. CONSTITUTION:Balancing piston cylinders 113 connected to each gas reservoir 114 works as a first buffer supporting device capable of almost disregarding a spring constant while supporting weight of a superstructure 2. In this state as it is, restoring force of the superstructure 2 is almost zero and an attitude of the superstructure 2 varies according to a variation in load very slowly so that a controlling piston cylinder 109 as a second buffer supporting device being supported by a servocontroller is installed there, whereby the superstructure 2 is controlled so as to keep up a state approximate to a standstill to space.
