PROBLEM TO BE SOLVED: To provide a joint mechanism which prevents dust and bacteria from entering thereinto and maintains the sanitary condition.SOLUTION: A joint mechanism includes: a cylindrical body 21 having a take-in opening part 21b for taking water from a water container 30 for a water server, in which the water is stored, into the water server; and a shutter body 22 which closes the take-in opening part 21b so that the take-in opening part 21b can open. The shutter body 22 includes: a shutter part 25 which slides on an outer periphery of the cylindrical body 21 to open or close the take-in opening part 21b; and a biasing part 26 which biases the shutter part 25 so that the shutter part 25 covers the take-in opening part 21b. The water container 30 for the water server is attached to the joint mechanism and the joint mechanism supplies the water from the water container 30 for the water server to the water server.SELECTED DRAWING: Figure 9 |
