LIQUID FEEDING/RECEIVING JOINT DEVICE AND FUEL CELL SYSTEM EQUIPPED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a liquid feeding/receiving joint device and a fuel cell system equipped with the liquid feeding/receiving joint device releasing load applied to an erroneous connection preventing key to prevent the damage of the erroneous connection preventing key when predetermined or larger turning force is applied in the connected state of a liquid acceptor and a liquid reservoir to relatively rotate both of them.

SOLUTION: The liquid feeding/receiving joint device comprises: a first joint device 10 having a male type joint part 14; and a second joint device 50 having a female type joint part 54 receiving the male type joint part 14 and connected to the first joint device 10. The female type joint part 54 has ribs 68A-68D inserted in the mutual clearances of projecting type locking parts 16A-16D of the male type joint part 14 when receiving the male type joint part 14. When the predetermined or larger turning force is applied in the inserted state of ribs 68A-68D in the respective clearances to rotate the first joint device 10 relative to the second joint device 50, the ribs 68A-68D elastically deform the projecting type locking parts 16A-16D to relatively move in the rotating direction and are inserted in the clearances different from the above.
