Abstract
In a power transmission system, a ring gear of a first speed reducer and a ring gear of a second speed reducer are coupled to each other and have the same rotational axis. An engagement portion between the ring gear and a planetary gear is formed such that, when a first motor generates a rotational torque in the forward direction, a force acts on the ring gear in a direction approaching the second speed reducer in the rotational axis direction. An engagement portion between the ring gear and a planetary gear is formed such that, when a second motor generates a rotational torque in the forward direction, a force acts on the ring gear of the second speed reducer in a direction of approaching the first speed reducer in the rotational axis direction.
