Abstract

A liquid send/receive joint device that releases pressure on a false connection prevention key and prevents breakage of the false connection prevention key when a rotary force of a predetermined level or greater is applied to the liquid send/receive joint device while a liquid accepter and a liquid reservoir are connected to each other, is provided. A fuel cell system equipped with such a liquid send/receive joint device is also provided. The liquid send/receive joint device includes: a first joint member 10 having a male joint part 14; and a second joint member 50 that has a female joint part 54 to receive the male joint part 14 and is connected to the first joint member 10. The female joint part 54 has ribs 68A to 68D that are inserted into spaces between adjacent engagement protrusions 16A to 16D of the male joint part 14 when the female joint part 54 receives the male joint part 14. When a rotary force of a predetermined level or greater is applied to the liquid send/receive joint device with the ribs 68A to 68D inserted in the respective spaces and then the first joint member 10 rotates relative to the second joint member 50, the ribs 68A to 68D cause the engagement protrusions 16A to 16D to elastically distort and move relatively in the direction of rotation, and make each engagement protrusion 16A to 16D be inserted into another space.
