Abstract
A railcar steering bogie includes a bogie frame, a wheelset, an axle box suspension, a steering mechanism configured to steer the wheelset, a brake unit, and a brake unit support link. The brake unit includes: a main body frame; a brake shoe supported by the main body frame and pressed against a wheel tread of the wheel during braking. The brake unit support link couples the axle box suspension and the brake unit and transmits displacement of the axle box in a car longitudinal direction to the brake unit at least during steering performed by the steering mechanism. The brake unit support link restricts the brake unit from being displaced outward in a car width direction by a predetermined distance or more during the braking. At least one of a side surface of the brake unit support link and a side surface of the brake unit includes a sliding surface.
