Abstract:
A railcar bogie includes: a bogie frame including a cross beam and plate springs and being rotatable relative to a bolster in a yawing direction, the cross beam extending in a car width direction, the plate springs supporting both respective car width direction end portions of the cross beam and extending in a car longitudinal direction; and stoppers provided at the bogie frame and configured to contact interference members to restrict a rotation range of the bogie frame when the bogie frame rotates relative to the bolster in the yawing direction, the interference members being connected to the bolster. When the bogie frame is located at a neutral position relative to the bolster in the yawing direction, the stoppers are arranged at car width direction lateral sides of the cross beam so as to overlap the cross beam in a side view.
