<p>A drainage trap (1) where the inside of a body (5) can be simply and easily cleaned and where a containing space (7) and a discharge space (8) that are partitioned by a partition body (9) can be precisely closed against each other. The drainage trap (1) has the blind tubular body (5) having an inner space (4) communicating with both a receiving section (2) and a discharge section (3), a lid body (6), and the partition body (9) for partitioning the inner space (4) of the body (5) into the containing space and the discharge space. The partition body (9) can be inserted into and fixed to the inner space (4). The partition body (9) and a side wall section (5a) of the body (5) have closure sections (14) that take pressing force in the vertical direction to cause a part of the partition body (9) to be in intimate contact with a part of the side wall section (5a) with a vertical component force acting on the part of the side wall section (5a). The partition body (9) is provided with a valve body (15) that, when liquid with a quantity greater than a predetermined level is contained in the containing space, comes up in order to allow the liquid to flow from the containing space to the discharge space, and with a valve seat (16) for receiving and supporting the valve body (15).</p> |
