PURPOSE:To effectively absorb the transmission of vibration to a driver's room by supporting the lower part of the driver's room on a chassis through a plurality of springs and rubbers and supporting one edge of the driver's room in swingable manner on a shaft supported by a movable spherical body on the chassis. CONSTITUTION:A spherical body 10 is installed in rotatable manner by an installation plate 9 at the center part of a chassis 5, and a shaft 6 is fixed on an arm 12 extending from the spherical body 10, and one edge of the bottom part of a vertical operation chamber is fixed through an arm at the left and right of the shaft 6. Further, a driver's room 1 is elastically supported on the chassis through a buffer member in the combination of a spring 2 and a rubber 3 at four places on the bottom part of the driver's room, and the impacts in the vertical and lateral directions which are applied on the driver's room 1 can be absorbed, and the load for an operation vehicle is reduced. |
