A teat cup assembly for an automatic milking machine including an inflation assembly having a retaining diaphragm integrally formed with the cup liner for engaging the teat of a cow to retain the cup against falling off while venting the space between the teat and liner at the end point of milking. The inflation is formed by initially molding the liner and diaphragm from a single mass of resilient elastic material, with the diaphragm having vent means integrally formed thereon to permit the egress of air into the liner at the end point of the milking operation. The configuration of the vent means facilitates molding the liner and diaphragm as a unitary structure.
