To provide a technique of miniaturizing a chassis device using a rocker bogie mechanism.SOLUTION: A chassis device includes: a driving wheel 24; a first driven wheel 26 disposed on one side in a longitudinal direction with respect to the driving wheel 24; a second driven wheel 28 disposed on the other side in the longitudinal direction with respect to the driving wheel 24; a bogie link member 38 supporting the driving wheel 24 and the first driven wheel 26 to be rocked around a first rocking shaft 44; and a rocker link member 40 supporting the second driven wheel 28 and the bogie link member 38 to be rocked around a second rocking shaft 50. The first rocking shaft 44 is positioned vertically above a rotation shaft 70 rather than on the same vertical line as the rotation shaft 70 of the driving wheel 24 and positioned inside an outer shape of the driving wheel 24 when seen from a right-left direction.SELECTED DRAWING: Figure 3
