A parallel cardan drive-type steering bogie (3) is provided with: a bogie frame (7); first and second axles (9) disposed along a vehicle-width direction at the front and the rear in a vehicle-length direction; a steering mechanism (30) which steers by rotating both the first and second axles (9) with respect to the bogie frame (7); first and second electric motors (12) which are respectively disposed, in a state of being supported on the bogie frame (7), at the front and the rear in the vehicle-length direction, and which are respectively provided with first and second output shafts (28) that are parallel with respect to the first and second axles (9) when steering is not being performed; first and second reduction gears (13) respectively connected to the first and second axles (9); and first and second constant-velocity ball joints (15) which respectively couple the first and second output shafts (28) to the first and second reduction gears (13), and which are made to track the rotation of the first and second axles (9) during steering to cause relative displacement of the first and second output shafts (28) and the first and second reduction gears (13).
