<P>PROBLEM TO BE SOLVED: To provide a teat cup having a sufficiently long service life. <P>SOLUTION: The teat cup 12 includes a teat cup liner 32 and a teat cup shell 31 formed in a cylindrical shape so as to be able to house a bore part 63 of the teat cup liner 32. The teat cup liner 32 is attached to the teat cup shell 31 in such a way that the bore part 63 is housed. A projecting part 44 for regulating a crushing direction, which projects toward the center of the teat cup shell 31, is provided on a portion of the inner surface of the teat cup shell 31 opposite to the bore part 63. The projecting part 44 is specified to have a projection height such that when a vacuum pressure is supplied at least between the teat cup shell 31 and the teat cup liner 32 (outside space S2), a peripheral face of the teat cup liner 32 makes contact with a projecting end T of the projecting part 44. <P>COPYRIGHT: (C)2013,JPO&INPIT |
