PROBLEM TO BE SOLVED: To prevent a water stop valve from being vibrated when water is passed in the connection structure of the water passage pipe for connecting the water passage pipe being arranged under the floor to the water stop valves of a toilet, a washstand, a sink, or the like through the penetrating metal fitting of a floor plate. SOLUTION: In the connection structure of a water passage pipe for connecting a water passage pipe 27 being provided at the lower portion of a floor plate 1 to a water stop valve 7 of a toilet, a washstand, a sink, or the like, a penetrating metal fitting 28 for inserting the water passage pipe 27 through an insertion hole 2 being punched at the floor plate 1 is fixed, the water stop valve 7 connects a joint member 9 for connecting the water passage pipe 27, a projecting part 21 is formed at either the joint member 9 or the feedthrough metal fitting 28, and an insertion hole 32 where the projecting part is fitted is formed at the other, thus fixing the water stop valve 7 to the penetrating metal fitting 28.
