PROBLEM TO BE SOLVED: To provide a support device for the operator's cab of a construction vehicle capable of inhibiting rolling in the presence of vertical vibration. SOLUTION: In the support device for the operator's cab of a construction vehicle, a floor frame 2 forming the lower portion of the operator's cab 1 is provided with a low floor section 2a and a high floor section 2b located in respective longitudinal positions on side view which are a predetermined distance away from each other vertically, and a vibration-isolating mount device is mounted between the low floor section 2a, the high floor section 2b, and a body frame 3 to elastically support the operator's cab 1. The support device includes a first support means 20 for damping the vertical vibration of the operator's cab 1 and a second support means 40 for inhibiting horizontal oscillation while permitting vertical and longitudinal vibrations.
