1. A gutter for recovering lubrication oil, particularly for a mechanical reducer of an aircraft turbomachine, comprising an annular main body around a central axis, and a deflector attached to the main body and configured to allow the evacuation of the oil radially from an inner cavity of the main body toward the outside of the gutter, the deflector comprising a main sleeve disposed in the continuity of the main body, and an evacuation channel configured to deflect oil from the main sleeve and having a curved shape such that a first end of the evacuation channel, communicating with the inner cavity, is tangent to the main body, the evacuation channel then gradually deviating, due to its curved shape, all the way to a second end directed outward with respect to the annular main body, wherein the curved shape of the evacuation channel comprises an axial component such that the evacuation channel is configured to deflect oil from the main sleeve in the direction of the central axis.
