PROBLEM TO BE SOLVED: To simplify an opening/closing type milker by providing an opening/ closing mechanism using an elastic body. SOLUTION: In this milker having the opening/closing mechanism for sealing/ opening the inside of a milker tube 1, the opening/closing mechanism has an air port 34 communicating with the inside of the milker tube and a button 37 provided on the air port and formed of an elastic body. An air passage 36 communicating with the air port in a direction vertical to the air port is provided in an upper part of the air port, and the air passage is provided with at least one opening 361. The opening is sealed by a seat valve 371 to be extended downward from the button, and the seat valve is deflected by pushing the button to open the opening. Sealing condition and opening condition can be thereby easily formed without using a complicated valve mechanism. COPYRIGHT: (C)2003,JPO
