FIELD: mechanical engineering.
SUBSTANCE: sliding support includes a housing, a shaft, an antifriction bushing and a rotation direction locking mechanism. Anti-friction bushing is made with recesses on end sides forming ratchet teeth, and the locking elements are made in the form of at least four elastic spring elements with bent free spring ends mating the antifriction bushing end ratchet teeth with possibility of their wedging. Elastic spring elements are located in turn in radial direction and make two locking units, one of which is fixed on shaft shoulder, and the other one is fixed on inner surface of housing. Directions of bent free spring ends forming ratchet teeth are opposite for these units.
EFFECT: providing relative rotational movement in the sliding support at any rotation angle, including those exceeding 360°.
