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 a fluid from a fluid container 30, in which the fluid is stored, into a liquid feeder; 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 and 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 fluid container 30 is attached to the joint mechanism and the joint mechanism supplies the fluid from the fluid container 30 to the fluid feeder.SELECTED DRAWING: Figure 9 |
