PROBLEM TO BE SOLVED: To provide an abnormality detection device of a railway vehicle which detects an abnormality of a rotating mechanism possessed by the railway vehicle.SOLUTION: An abnormality detection device of a railway vehicle has a third acceleration sensor 34C arranged in a railway vehicle 100, and a calculation processing part 90 arranged in a vehicle body of the railway vehicle 100. The abnormality detection device of the railway vehicle derives components from third X axial data SX3 and third Y axial data SY3 by using the calculation processing part 90, calculates a third mutual correlation value by obtaining a high-frequency component PX3 from the third X axial data, and obtaining a low-frequency component PY3 from the third Y axial data, and performs abnormality determination when the obtained numerical value satisfies a specified condition.SELECTED DRAWING: Figure 4
