In the attachment structure for the drainer of the present invention, the position of the external drainage hole and the position where the drainer attachment piece is fixed by the fixture may be different from each other in the longitudinal direction of the drainer.
According to such a configuration, the water drained to the outside from the external drainage hole flows down along the draining mounting piece without passing through the above-mentioned fixed position, and as a result, the water drains from the above-mentioned fixed position. The risk of water flooding into the building frame can be further reduced.

In the drainer mounting structure of the present invention, the drainer locator piece may extend upwardly than the drainer main body piece, and the prospective space may be formed between the drainer locator piece and the sealing material.
According to such a configuration, water such as rainwater flowing into the prospective space can be prevented from entering between the waterproof sheet and the draining material by the extending draining piece, and therefore waterproofness can be further improved.

In the draining member mounting structure of the present invention, the draining end piece may be inclined such that the outdoor end thereof is located below the indoor end.
According to such a configuration, the water flowing down from the drain hole is guided toward the outdoor side by the slanted drain prospect as described above, so that drainage performance can be improved.
