FIELD: machine building.
SUBSTANCE: invention relates to mechanical engineering, in particular to the hinge joints of machine parts. Single-contact four-mobile kinematic pair consists of a connection between a supporting link and an acting link. Support link is made in the form of a hole of constant negative Gaussian curvature. Acting link is made in the form of a circular barrel, forming which is an arc of a circle with a radius that in absolute value is equal to the radius of curvature of the support link.
EFFECT: possibility of three relative rotational movements to provide one relative translational motion of the links.
