Abstract
A railcar bogie includes: a cross beam extending in a car width direction; a first traction motor supported by a first car longitudinal direction portion of the cross beam; a second traction motor supported by a second car longitudinal direction portion of the cross beam; and a coupling member arranged under the cross beam and between the first traction motor and the second traction motor and coupling the first traction motor and the second traction motor to each other.

A railcar bogie comprising:
- a cross beam extending in a car width direction;
- a first traction motor supported by a first car longitudinal direction portion of the cross beam;
- a second traction motor supported by a second car longitudinal direction portion of the cross beam;
- and
- a coupler (i) arranged under the cross beam and between the first traction motor and the second traction motor, (ii) coupling the first traction motor and the second traction motor to each other, and (iii) configured to cancel out a swinging motion of the first traction motor and a swinging motion of the second traction motor, wherein
- the first traction motor is arranged at a first side in the car width direction;
- the second traction motor is arranged at a second side in the car width direction;
- in a plan view, a swing axis of the first traction motor is inclined relative to the car width direction;
- and
- in the plan view, a swing axis of the second traction motor is inclined relative to the car width direction.
