Disclosed is a vehicle, in particular rail vehicle, with a wagon body and an running gear on which the wagon body is supported, wherein the wagon body and the running gear define a vehicle longitudinal direction, a vehicle transverse direction and a vehicle height direction. A tilting mechanism is arranged between the wagon body and the running gear, which is designed to impose, during a transverse displacement in the vehicle transverse direction, upon the wagon body a rolling motion about a rolling axis parallel to the vehicle longitudinal direction. The tilting mechanism comprises a transverse decoupling device, which is designed to reduce the stiffness of the tilting mechanism against a pure transverse displacement of the wagon body with respect to the running gear. The invention furthermore relates to a corresponding tilting mechanism.
