In order to provide a retraction device, which is as simple as possible in design, for an insert which is displaceable in the pulling-out direction from a unit by means of a pulling-out guide mounted in a roller bearing, in which device retraction of the insert into the end position of the insert takes place over a predetermined retraction path without additional operating elements, it is proposed that a connecting part is provided, which is displaceable between a first and a second position in the pulling-out direction and on which an elastic energy store engages, that the storage of the energy is effected by a catch element which engages on the connecting part when the insert is pulled out and moves said connecting part from the first position into the second position, that the connecting part can be fixed in the second position and the catch element as well as the connecting part can be disengaged when the insert is pulled out beyond the retraction path, and that, when the insert reaches the second position while being pushed in, the connecting part can be released and brought into engagement with the catch element for retraction of the insert. <IMAGE> |
