FIELD: parallel connection of parts by means of axle. SUBSTANCE: hinged joint includes first constructional member having two parts connected mutually in parallel, spaced one from another and having circular openings arranged one opposite to another. Hinged joint also includes sleeve rigidly connected with second constructional member and arranged between connected parts coaxially relative to their openings. Supporting axle passes coaxially through supporting sleeve. Its end portions pass through said openings. Each end portion of axle has extending outwards recesses forming inner cone surface with predetermined conicity and peripheral clamping zone restricted by said cone surface. Hinged joint also includes two members designed for engaging one with another and made the form of cone ring for each clamping zone; two threaded members passing through central opening of cone ring and central opening of supporting axle for axially shifting rings in said recesses. Clamping zones are arranged in such a way that butt joint is formed between supporting axle and constructional parts by action of threaded members. Supporting axle is in the form of sleeve with cylindrical through opening whose diameter is equal to minimum diameter of recesses. Supporting sleeve includes sliding bearing with cylindrical insert provided on its each end with inner elastic sealing dent made monolithically with insert.
