Abstract

A syringe having a bearing divided at least once in the axial direction of a threaded rod into bearing parts. The bearing parts are held at a distance from one another and at a distance from the threaded rod by at least one expanding part. The bearing parts, on their surfaces facing the threaded rod, have surfaces which can be brought by external pressure into engagement with the threaded rod against the resistance of the bearing parts.
