1. A tripod joint comprising:

  • an outer joint part provided with three axially extending longitudinal recesses with circumferentially opposed tracks;

    an inner joint part with three radial circumferentially distributed arms which each engage one of the longitudinal recesses and carry roller assemblies each including a roller carrier and a roller element, said roller elements rollingly guided in the axial direction in the longitudinal recesses of the outer joint part on the tracks, with each roller carrier provided with a cylindrical inner recess and guided on a spherical arm end of a respective one of said arms so as to be pivotable and longitudinally movable relative to an axis of the respective arm, said roller element rotatably supported on the roller carrier, and said roller assemblies each including the roller carriers and the roller elements being supported on the outer joint part to prevent the roller assemblies from tilting around the longitudinal axis of the inner joint part; and

    havinga radially inwardly directed edge of the inner recess of each roller carrier including at least one elastically deformable projection or an elastic deformable bead said projection or bead may be guided past the respective arm end in being elastically deformed without being destroyed, wherein said projection or bead provides a form-fitting resistance to prevent said roller assembly from axial removal from its respective arm.
