DRAINAGE MEMBER

PROBLEM TO BE SOLVED: To provide a drainage member having the following features: 1. air is not stuck in a lateral drainage tube; 2. a drain flow rate is increased; and 3. inner self-cleaning activity of a drainage tool is enhanced.SOLUTION: A drainage member comprises: a drainage tool 1 comprising an outlet 2 in a side surface direction; and a lateral drainage tube 3 extending from the outlet 2 of the drainage tool 1. A blocking wall 4 partially blocking inside of the outlet 2 is constructed. With the blocking wall 4, an opening allowing a flow of drainage and air is constructed at least an upper half of the outlet 2 and a lower half comprising a part at around the lowest part of the outlet 2. 【課題】１．排水横管内に空気を貯留させない、２．排水流量を増加する。３．排水器内の自浄性を高める。【解決手段】側面方向に排出口２が備えられる排水器１と、排水器１の排出口２から延出する排水横管３と、から構成される排水部材において、排出口２内の一部を遮蔽する遮蔽壁４を構成するとともに、当該遮蔽壁４によって、排出口２の少なくとも上半分の一部と、排出口２の最下端周辺を含む下半分の一部に、排水及び空気が流れる開口を構成したことを特徴とする。【選択図】図５
