PURPOSE:To increase the degree of freedom in layout and reduce the manufacturing cost of a gas spring by forming the casing of gas spring in a cylindrical shape, as well as mounting multiple number of gas springs adjacent to a hydraulic cylinder. CONSTITUTION:Gas springs 18, whose casing 19 are formed in cylindrical shape whose movable bulkheads 20 are composed of movable pistons, are mounted adjacent to a hydraulic cylinder 6 and in parallel with the hydraulic cylinder 6. Gas springs 18, 3 pieces each, are provided on right and left for front wheels, and 2 pieces each on right and left for rear wheels, and the 3 pieces for front wheels are mounted just like surrounding the hydraulic cylinder 6 and abutting each other, and these gas springs 18 are connected to each other at the area near their bottom edges by a plate shape connecting bracket 98 welded to the casing 19. Also, as to the gas springs 18 for rear wheels, their construction is the same as that for front wheels except that they are two springs. |
