To provide a simple mount device which can minimize a spring constant of a weight support and can restrain run-out of slant direction of a driver's seat installation body with respect to an airframe frame and vertical horizontal vibration.
The mount device disposes the driver's seat installation body 21 on the airframe frame 12 and disposes a vibration damping mechanism portion 22 between the airframe frame 12 and the driver's seat installation body 21. The vibration damping mechanism portion 22 fixes a plurality of cylindrical mounts themselves 23 on one side and the other side of the airframe frame 12 and fits to make it possible to vertically move both rods type of a piston 24 in each of the mounts themselves 23, respectively, and forms to partition upper and lower chambers 25, 26 in the mount themselves 23. The device is in fluid communication with the upper chamber 25 formed on the left side of the mounts themselves 23 and the lower chamber 26 formed on the right side of the mounts themselves 23 by one piping 31 which enables fluid accompanied with resistance to move. The device is in fluid communication with the lower chamber 26 formed on the left side of the mounts themselves 23 and the upper chamber 25 formed on the right side of the mounts themselves 23 by other piping 32 which enables fluid accompanied with resistance to move.
