Railcar bogie

A railcar bogie comprising:

• a wheelset including:
• an axle extending in a car width direction, and
• a pair of wheels provided at both respective car width direction sides of the axle;
• a bearing configured to rotatably support the wheelset;
• an axle box including:
• an upper axle box element covering the bearing from above the bearing, and
• a lower axle box element fixed to the upper axle box element by a fastening member and covering the bearing from below the bearing;
• and
• an obstacle deflector including:
• an obstacle deflecting portion arranged at one side of the wheel in a car longitudinal direction and, when viewed from the one side in the car longitudinal direction, the obstacle deflecting portion overlaps at least one wheel, and
• a coupling portion configured to couple the obstacle deflecting portion to the axle box, the coupling portion of the obstacle deflector being fixed to a receiving seat provided at the upper axle box element, wherein:
• when viewed from the car width direction, the receiving seat is provided at a region of the upper axle box element, and
• the region is located at the one side of an axle center in the car longitudinal direction and intersecting with a horizontal line extending in the car longitudinal direction through the axle center.
