PURPOSE: An armored car is provided to improve riding comfort by doubly absorbing ground shocks through a suspension device. CONSTITUTION: An armored motorcar comprises a car body, a road wheel(3), an arm(33), and a suspension device(5). The road wheel supports a caterpillar. One end of the arm is connected to the rotary shaft of the road wheel. The suspension device is installed between the car body and the road wheel and joined with the car body to connect the road wheel to the car body. The suspension device comprises a crank unit(51), a damping unit(52), and a gas spring unit(53). A crank chamber(511) of the crank unit has a first piston(515) connected to the arm. A damper of the damping unit is installed in an oil chamber(521,522). One side of a second piston(532) of the gas spring unit faces an oil seal while the other faces a gas chamber(531).
