PROBLEM TO BE SOLVED: To provide a new carriage capable of more suitably suppressing vibration of a cabin during traveling. SOLUTION: In a support device A for supporting a cabin on a carriage body, a plurality of air suspension mechanisms 3 are constituted of a plurality of air springs 31 and 32, and operation states of the air springs 31 and 32 are switched through a controller 4 to change spring constants. As a result, when a natural frequency of the cabin 2 is overlapped with a frequency range with high human sensitivity, the spring constants are switched to shift the natural frequency, and riding comfort can be effectively improved without requiring replacement of the springs 31 and 32.
