PROBLEM TO BE SOLVED: To provide a vehicle body inclining device of a railway vehicle which can start an exhaust operation swiftly when an air spring on a curved inner rail side rises during passage of a curved part.SOLUTION: A vehicle body inclining device of a railway vehicle comprises: an air spring 4 placed on a carriage 3 and supporting a vehicle body 2; a passive adjusting valve 6 which is provided in a first air passage 7 for supplying and exhausting air to and from the air spring 4, and to which an adjusting link 5 is fitted horizontally; and an inclination adjusting valve 10 which is provided in a second air passage 11 for supplying and exhausting air to and from the air spring 4, and to which an adjusting link 9 is fitted obliquely. Each of the passive adjusting valve 6 and the inclination adjusting valve 10 comprises an air supply valve 18, an exhaust valve 19, air supply valve hydraulic damper mechanisms 21, 23, 31, and exhaust valve hydraulic damper mechanisms 21, 25, 32. A diameter of an orifice 32 of the exhaust valve hydraulic damper mechanisms 21, 25, 32 of the passive adjusting valve 6 is larger than a diameter of an orifice 31 of the air supply valve hydraulic damper mechanisms of the passive adjusting valve 6.SELECTED DRAWING: Figure 2
