PROBLEM TO BE SOLVED: To solve the problem of a suction object flowing into a suction pump.SOLUTION: A suction apparatus comprises: suction pipelines having one end at which a suction port is formed a suction pump that energizes the suction pipelines with suction force a container that is provided on the suction pipelines and stores a suction object sucked through the suction port and an auxiliary container that is provided on suction pipelines between the container and the suction pump and stores a suction object flowing in from the container. The auxiliary container includes a spiral flow passage member inside the auxiliary container, the spiral flow passage member including an inflow passage for making a fluid spirally flow in through a port connecting with a suction pipeline on the container side.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2017,JPO&INPIT【課題】吸引物が吸引ポンプに流入してしまう問題を解決すること。【解決手段】本発明の吸引装置は、一端に吸引口が形成された吸引管路と、この吸引管路に吸引力を付勢する吸引ポンプと、吸引管路上に設けられ吸引口から吸引した吸引物を蓄積する容器と、当該容器と吸引ポンプとの間の吸引管路上に設けられ容器から流入した吸引物を蓄積する補助容器と、を備える。そして、補助容器は、当該補助容器内に、容器側の吸引管路との連結口から流体を螺旋状に流入させる流入路を有する螺旋流路部材を備える。【選択図】図7
