The cross beam includes a pair of pipe members extending in the car width direction and lined up so as to be located away from each other in a car longitudinal direction, and air spring seats provided at upper surfaces of car width direction end portions of the pair of pipe members. At least one of the pair of pipe members includes a curved portion at a car width direction middle portion thereof, the curved portion projecting outward in the car longitudinal direction such that a clearance between the pair of pipe members increases.
