Figure 12 shows the case (・1) of a dialysis machine for an artificial kidney machine that is currently commonly used.
1) has a cylindrical shape having a dialysate inlet (3) and a waste product outlet (4) in the vicinity of the open ends (2) (2) on both sides with a threaded portion a) (2a) formed on the outer peripheral surface. The transparent polycarbonate case body (5) and this case body (5)
) is made of urethane or the like fixed to the inner peripheral surface of the open end (2) (2). The annular receiver is composed of members (6) and (6). A large number of hollow fibers (7) made of dialysis membranes are accommodated in the case (1).
7) At the same time, blood containing waste products flows from the top to the bottom of the case (1) from the dialysate inlet (3).
), the dialysate flows through the gap between the hollow fibers (7) from the bottom to the top, and due to the convection of these two fluids, waste products in the blood are taxed and diffused into the dialysate. The blood is discharged from the discharge port (4) and is used for cleaning.

By the way, both open ends (2) (2) of the above case (1)
are camped to prevent blood leakage. FIGS. 13 and 14 show this type of conventional cap structure. In the same figure, (8) is the blood flow hole (8a)
This cap (8) has a flange portion (9) with an enlarged diameter at one end and a pipe connection port (10) at the other end. An annular groove (12) is formed in the end surface (11) of the flange portion (9). (13) is the above cap (8)
An annular sealing member made of an elastic material such as rubber is fitted into an annular groove (12), and (14) is an annular locking member made of synthetic resin, and this locking member (14) has the above-mentioned cap at one end. An inner flange portion (15) is formed to engage with the flange portion (9) of (8), and a screw hole (16) is formed on the inner peripheral surface.
). Then, when capping the open ends (2) (2) of the case (1), the cap (
In the annular groove (12) of 8), an annular seal member (
13), press the flange (9) of the cap (8) against the open end (2) (2) of the case (1), and push the locking member (14) against the open end (2) ( 2
) and tighten, using the inner flange (9) of the locking member (14) to connect the flange (9) of the cap (8).
Press. Then, the annular seal member (13) is elastically deformed, and the receiver provided on the inner circumferential surface of the open end (2) of the case (1) becomes the end face (6a) of the member (6) (6). (6

Be ° ゝWhen assembling parts to the open end (2) (2) of the case (1) and capping it, a large number of camps (8) in which the annular seal member (13) is fitted into the annular groove (12) are prepared in advance. However, the annular seal member (13)
Since it is molded slightly larger than the annular groove (12) of the cap (8), it is difficult to fit into the annular groove (12) and easy to come off. After the member (13) is fitted, the caps (8) are placed in an upward position so that the seal member (13) does not come off the annular groove (12). In this way, in the conventional cap structure, since the caps (8) are placed side by side in an upward position when assembling the parts, it is easy for dust to adhere to the inside of the caps (8), and since there are a large number of parts,
It is easy for bacteria to enter the case (1) when assembling the parts, and it takes time to assemble the parts, resulting in extremely poor assembly workability.
) were often removed from the annular groove (12), resulting in defective products.
