DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. As shown in FIGS. 1 and 2, the drainage basin body 1 is a container having a substantially rectangular shape in a plan view with an open top, and a part of the bottom surface portion, in the embodiment, the longitudinal end of the bottom surface portion. A drainage port 2 is provided in the section. The bottom surface of the drainage basin body 1 has a gentle slope so as to incline downward toward the drainage port 2 side. A collar piece 7 is provided outward at the opening edge of the upper opening of the drainage basin body 1, and a lid mounting step 8 is provided inside the opening edge. In addition, the drainage port 2 has a connecting tubular portion 6 hanging downward. The drainage basin body 1 having such a configuration is entirely formed by press-molding a metal such as stainless steel.

As shown in FIG. 2, the trap device 3 is constructed by providing water sealing means on the outer container body 5, and in the embodiment shown in the accompanying drawings, the outer container body 5 made of metal such as stainless steel is used. An upward cylinder 9 made of metal such as stainless steel is provided in a projecting manner in a hole in the bottom portion, and a bell-shaped cap 11 having a downward opening with a perforated plate 10 attached to the upper cylinder 9 is loosely fitted in the upward cylinder 9.

Here, the upper end of the outer container body 5 made of metal such as stainless steel is a fitting portion 12 having a large diameter and having an L-shaped cross section, and the vertical piece 13 of the fitting portion 12 is drained. Connecting cylinder 6 hung in the drainage port 2 of the main body 1
3 is fitted to the outer peripheral surface side of the connecting cylinder 6 and the upper end portion of the outer container body 5 in this state by pressing in the radial direction of the connecting cylinder portion 6 by pressing to be integrated as shown in FIG. . Here, FIG.
Reference numeral 14 is a press-bonded portion. The crimping portion may be provided over the entire length in the circumferential direction, or may be partially provided in the circumferential direction. In this way, the metal connecting cylinder portion 6 and the upper end portion of the metal outer container body 5 are pressed in the radial direction of the connecting cylinder portion 6 by pressing, thereby trapping in the drainage port 2 of the drainage basin body 1. This makes it possible to prevent the formation of a recess in which water is accumulated in the portion where the device 3 is mounted. When integrated in this way, the fitting portion 12 having an L-shaped cross section
A part of the horizontal piece 15 is located inside the connecting cylinder portion 6, and when the cap 11 of the lower opening having the eye plate 10 attached from above is fitted into the drainage port 2, the eye plate 10
The outer peripheral end portion of is mounted on and supported by the horizontal piece portion 15. Therefore, the lower end of the cap 11 and the outer container body 5
A gap is formed between the cap 11 and the bottom surface of the cap 11.
A gap is formed between the upper surface of the above and the upward cylinder 9. The upward cylinder 9 is made of metal. To mount the upward cylinder 9 by projecting it into the hole at the bottom of the metal outer container body 5, the diameter of the lower outer circumference of the upward cylinder 9 should be reduced. The male screw portion 16 is provided in the smaller portion of the upper cylinder, the lower portion of the upward cylinder 9 is fitted into the hole of the outer container body 5 so that the male screw portion 16 projects downward, and the step above the male screw portion 16 of the upward cylinder is the outer container. The upper surface of the bottom of the body 5 is pressed against the periphery of the hole, and in this state, the lower cylinder 19 made of synthetic resin having the female screw portion 17 on the inner circumference of the upper end is arranged below the outer container body 5 and the female screw portion 17 is externally threaded. It is mounted by screwing onto the portion 16 and pressing the upper end surface portion 18 of the lower cylinder 19 against the periphery of the hole portion on the lower surface side of the bottom portion of the outer container body 5.

A perforated lid 20 made of metal such as stainless steel is removably placed on the lid mounting step 8 inside the opening edge of the upper opening of the drainage basin body 1. Therefore, the floor drainage basin 4 having the above-mentioned configuration is used, for example, as a drainage basin in a bathroom washing room, and drainage flows into the drainage basin body 1 through the hole 21 provided in the lid 20 to drain the drainage basin. Masu body 1

The water is drained from the upward pipe 9 through a gap between the portion and the upward pipe 9. In this case, water is always accumulated and sealed up to the upper end of the upward cylinder 9 of the outer container body 5, so that a so-called trap action is performed. Then, the water is drained as described above, but the connecting cylinder portion 6 made of metal and the upper end portion of the outer container body 5 made of metal are pressure-bonded to each other in the radial direction of the connecting cylinder portion 6 by pressing to be integrated. By doing so, it is possible to prevent the water discharge port 2 of the drainage basin body 1 from being formed with a recess where water is accumulated in the portion where the trap device 3 is attached, and to prevent water from accumulating in this portion so that dirt is not attached. Therefore, when the lid 20 is opened and cleaned, the cleaning of this portion does not take time and the appearance is improved.

FIG. 4 shows another embodiment of the present invention in which the outer surface of the body of the drainage basin body 1 is recessed. In this way, when the outer surface of the drainage basin body 1 is dented to form the recessed portion 1a, when it is buried in concrete during construction, the concrete enters the recess 1a on the outer surface of the drainage basin body 1 and moves upwards. It will be prevented from coming off,
As a result, it is not necessary to attach a metal fitting to prevent the metal from coming off.
