It is located below the flange of the main body of the drainage device, and on the peripheral surface of the main body, there are provided recesses for engagement having upper and lower curved surfaces, and at the plural positions of the ring-shaped attachment member, An attachment device for a drainage device has been filed in which a lever having an engaging projection that is press-fitted into a recess is pivotally pivotally mounted. (Practical application Sho 63-121735).

(Problem to be Solved by the Invention) In the former case of the conventional drainage attachment device configured as described above, the female screw portion of the attachment member is screwed into the male screw portion provided in the main body. Since the drain is attached to the sink only by such means, it seems that it is extremely easy and easy at first glance, but in general, the attachment work of the drain is a narrow place, and the sink is also involved. Since it is performed from above and below, it is unexpectedly difficult to accurately screw the male and female screws, and it is easy for a screwing error to occur. There is often the problem of easy removal of parts.

Also, in the latter case of the above-mentioned conventional examples, compared to the above-mentioned known one, the attachment member is certainly much easier to attach to the drainer body, and the drainer can be surely and easily installed in the sink or the like. It has a great advantage that it can be attached to other sinks, but if, for example, it is necessary to attach a drain to the corner of the sink, or if the shape of the sink changes, If the shape of the main body of the device, especially the shape around the upper opening (attachment part to the sink) near the top and bottom of the main body is cylindrical as in the past, it may sometimes be difficult to attach the main body of the drain to the sink. Therefore, in such a case, it is necessary to use the drainage body of various tubular shapes other than the cylindrical shape. In such a case, like the latter drainage device attachment device in the above-mentioned conventional example, the attachment member has a ring shape (circular ring shape).
However, this causes a serious obstacle that the drain main body cannot be attached to the sink at all.

SUMMARY OF THE INVENTION The present invention aims to develop an attachment device for a drainage device that has the advantages of the latter attachment device for a drainage device in the above-mentioned conventional example and can eliminate the drawbacks thereof. It is extremely easy to attach the attachment member to the
Therefore, there is an advantage that the drainer can be reliably and easily attached to a sink such as a sink, and a drainer attachment device that can attach a drainer main body of a cylindrical shape other than a cylindrical shape to the sink surely is provided. The purpose is to
