PURPOSE:To prevent drinking water from leaking from a mounting part when mounting a faucet into the cover of a transportation storage tank and mount the faucet by means of a simple structure so that the spout of the mounted faucet can be turned directly down at all times. CONSTITUTION:A first holding edge 31, an O-ring mount groove 33, and a second holding edge 32, which is larger in diameter than the first holding edge 31, are formed in that order on the spout side of a mounting threaded part 34 formed at the mounting end of each faucet 30. An O-ring 40, which is slightly larger than the second holding edge 32 and made of an elastic material, is mounted into the groove 33. Also, a cover 20 forms an O-ring storage part 23 having a diameter which is large enough for the second holding edge 32 to be inserted in and having a depth for at least half the pitch of the mounting threaded part 34; and a mounting threaded part 25 inside the O-ring storage part 23, into which the mounting threaded parts 34 of the faucets 30 are screwed and fixed from both its sides. |
