小口径桝。[Scope of Claim for Utility Model Registration] An overflow dam is provided approximately at the center of the bottom of a small diameter basin made of synthetic resin, a drainage pipe channel is formed on one side of the dam, and a U-trap is opened upward on the other side. In a small-diameter basin in which the U-trap can swing freely relative to the basin body by providing a rotatable outlet, a downward opening is provided at the bottom of the basin body to which the outlet of the U-trap is joined. A diameter reduction bushing which is rotatable and prevented from falling out is fitted into the first trap socket with a ring-shaped seal interposed therebetween. A small-diameter basin equipped with a U-trap, characterized in that a second trap socket is formed on the inner periphery of the bush, and an outlet portion of the U-trap is adhesively bonded to the second trap socket.
