<p>Axial adjustment device (1) for a member (3) of a trailing cable transmission (2), provided with a fastening element (7) having first and second seats (8, 23) intersecting orthogonally with one another and adapted to be slidably engaged respectively by one end (10, 15) of the said member (3) and by a fixing element (24) movable between a normal position and a position for blocking the said member (3) in a desired axial position with respect to the fastening element (7), the device (1) being provided moreover with a thrust element (35) movable axially along the fastening element (7) towards the fixing element (24) under the load of a spring (36), first releasable relative constraining means (38, 40, 41) interposed between the thrust element (35) and the fixing element (24) and cooperating with one a other as a result of the action of the spring (36) in order to hold the fixing element (24) in the normal position, and second relative cam constraining means (39, 43, 27, 28) interposed between the thrust element (35) and the fixing element (24) which can be activated following deactivation of the first relative constraining means (38, 40, 41) and cooperating with one another as a result of the action of the spring (36) in order to transmit a radial load to the fixing element (24), adapted to bring the said fixing element (24) into the blocking position. <IMAGE></p> |
