    • PROBLEM TO BE SOLVED: To provide a liquid filled mount, which can be preferably used for a working machine etc., and can effectively control its vibration damping characteristic, and further to provide a cab supporting device and a seat supporting device.
      SOLUTION: The liquid filled mount 30 comprises a cylindrical body 33C in which MR fluid is enclosed, a rodlike body 32B which is brought into contact with the inside surface of the cylindrical body 33C and is arranged so as to slide with respect to the cylindrical body 33C, an elastic body 32C which deforms following the reciprocation of the rod shape body 32B in the cylindrical body 33C, a by-pass passage 41 which communicates with two regions, partitioned in the sliding direction of the rod shape body 32B, by means of the rod shape body 32B, and makes the MR fluid flow between these two regions, and a magnetic field generating means 43B for controlling the viscosity of the MR fluid by applying the magnetic field to the MR fluid flowing inside the by-pass passage 41, wherein the cylindrical body 33C keeps the elastic body 32C arranged inside.
