FIELD: agricultural engineering. SUBSTANCE: teat cup comprises a casing 1 with suction cup 2, flexible combined plates 3 installed diametrically in casing and provided with joints 4 at the ends. Casing has a removable lower portion 7. Internal surface of the casing is provided with circular guides 8 one of which is disposed in the upper part of the casing and the other one, in its lower part. Joints 4 of plates 3 are installed in guides 8 with a provision for transverse movement relative to the casing 1.
