A rail vehicle slack adjuster of the axial type has a barrel (4), a spindle (2), and an adjuster nut (29). In order to prevent the spindle (2) from leaving its thread engagement with the adjuster nut (29) the spindle is provided with a stop ring (64) so located that it will contact a barrel part (57) and, via the barrel and a barrel spring (53), bring about a closing of a main clutch (49, 50) between a pull means (6, 48) and the adjuster nut. |
