PURPOSE:To reduce mechanical friction loss against a coil spring by arranging said coil spring just above a tilt hinge, in suspension where the lower front end of a cab is supported by a pair of the right and left coil springs. CONSTITUTION:The lower front end part 1a of a cab 1 is supported by a pair of the right and left coil springs 2, and the lower end 2a of said coil spring 2 is placed on a spring receptacle member 3. A pair of the right and left link levers 4, also used for a spring cradle 4a of the coil spring 2, are engaged on a tilt hinge 7 on the upper end 6a of a cab mount bracket 6 fixed to a frame 5, and the rear end 4b of the link lever 4 is engaged 8a on the right and left brackets 8. The coil spring 2 is arranged just above the tilt hinge 7 of the cab mount bracket 6 such that the friction loss against said coil spring may be reduced. |
