FIELD: machine building.
SUBSTANCE: invention relates to mechanical engineering, in particular to the hinge joints of machine parts. Unijunction two-degree-of-freedom kinematic pair consists of a connection between a supporting link and an acting link. Support link is made in the form of a circular parabolic hole. Acting link is made in the form of a parabolic barrel, which forms congruent to a parabolic hole.
EFFECT: realization of the possibility of two relative rotational movements of the links with respect to two mutually perpendicular axes.
