FIELD: machine building.

SUBSTANCE: invention can be used in units of piston machines, in particular, internal combustion engines. Connecting rod and piston group comprises piston (1) installed in cylinder, in hole of which support pin (2) is hinged. In support pin (2) there is a transverse hole crossing longitudinal axis (3) of the support pin. In transverse hole of support pin (2) there is piston pin (4) having surface of hinged support. Surface of the hinged support interacts with the mating surface of the hinged support of connecting rod (7). Support pin (2) is equipped with thrust surfaces (8) made on its opposite sides. Support pin (2) is installed in hole of piston (1) with possibility of force transfer from hinged support of piston pin (4) to inner surface of cylinder by means of thrust surfaces.
