<p>PROBLEM TO BE SOLVED: To prevent the whirling of a piping due to relative rotation between a socket and a plug and wear of a packing, and to prevent the twist of a piping. SOLUTION: A ball lock type connector 1 connected to one end 2a of a piping 2 is formed such that hard balls 50 in respective hard ball containing holes 14 formed in the plug receiving part 11 of a socket 10 are fitted in a plurality of respective fit in recessed parts 24 formed with the same phase difference as that the rigid ball 50 contained hole 14 formed in the outer peripheral surface of the insertion cylinder part 21 of the plug 20, the socket 10 and the plug 20 are itercoupled with relative rotation therebetween prevented from occurring, and the whirling of the piping 2 and wear of packing 70 and 170 are prevented from occurring. A ball lock type connector 100 to connect the other end 2b of the piping 2 is fitted in a fit-in groove 122 peripherally continuously formed in the outer peripheral surface of the insertion cylinder part 121 of a plug 120. The socket 110 and the plug 120 are intercoupled in a relative rotatable state and the twist of the piping 2 is prevented from occurring.</p> |
