Le dispositif d'entraînement est pourvu : d'une source d'entraînement ; d'un boîtier pour loger la source d'entraînement ; et de l'élément d'entraînement, qui se déplace par la force d'entraînement générée par la source d'entraînement et transmet la force d'entraînement à l'élément mobile, l'élément d'entraînement étant au moins partiellement positionné à l'extérieur du boîtier.
