An improved pulley, characterized in that the fixing device the shaft is formed by three segments that are introduced in a frustoconical cavity of the axial area of the pulley, which segments are supported on a coplanar step to the face of the pulley where the smaller base of the cavity corresponds; fixed to said step by screws, which, when penetrating said segments, move them towards the interior of the cavity and as they slide through the frustoconical wall towards the minor base, they tend to join, pressing strongly on the axis of the pulley; while when unscrewing said screws, the pressure on the shaft ceases and the displacement or separation of the pulley and shaft is allowed.
