FIELD: mechanical engineering. SUBSTANCE: hinge joint has a housing, pin with spherical head received in the housing, and bushing embracing the spherical head and having through grooves. The grooves are open from the side of the end face and form tabs. Threaded cover is provided with a pit on the internal surface. The pit is shaped as a truncated cone. The housing has conical and cylindrical internal surfaces, a bigger threaded opening being on the one end and a smaller on the other. The internal conical surface is near the smaller opening. The external surface of the bushing tabs are conical from the side of the end face and identical to the inside surface of the housing. Other end of the bushing tabs are shaped as truncated cone. The through grooves of the bushing are radial. EFFECT: simplified assembling. 4 cl, 3 dwge
