An uncoupling pulley provided with a longitudinal axis includes a wheel rim including a first area, intended for receiving a belt connecting the wheel rim to a first power-transmission element, and a second area extending from the first area; a hub rigidly connected to a second power-transmission element; one of the power-transmission elements being driving and the other being driven; a ring gear including a first portion located under the second area and a second portion presented in the shape of at least one cylindrical skirt extending, from the first portion, along said longitudinal axis, the ring gear being capable of rotating relative to the wheel rim and/or the hub about the longitudinal axis; a device for driving the ring gear by the wheel rim; a resiliently deformable element, one end of which is attached to the hub and another end of which is attached to the ring gear; the cylindrical skirt being located opposite the resiliently deformable element, so that the resiliently deformable element can engage with the cylindrical skirt in said first relative direction of rotation.
