Abstract

A railcar bogie includes a cross beam, an axle box, a supporting member, a plate spring, and an axle beam. The axle box accommodates a bearing rotatably supporting a wheelset. The supporting member is provided at an upper portion of the axle box. The plate spring supports a car width direction end portion of the cross beam and extends in a car longitudinal direction, and the plate spring includes a car longitudinal direction end portion supported by the supporting member. The axle beam couples the axle box and the cross beam in the car longitudinal direction and is opposed to the plate spring in an upward/downward direction. An installation seat is provided at an upper surface of the axle beam and includes an installation surface on which a pushing-up device configured to push up a lower surface of the plate spring can be placed.
