Abstract: An easily polymerizable substance handling device is provided that can prevent generation of irregularities and steps between a pipeline and a cover member due to the cover member being installed at an opening part of the pipeline. A cover part 3 is formed to have a curved surface 3a on a side closer to inside of a pipeline 1. The shape of the surface 3a on the pipeline 1 side is preferably a concave shape when viewed from inside of the pipeline 1. The shape of the surface 3a of the cover part 3 on the pipeline 1 side is more preferably the shape of a curved surface having a curvature radius equal or approximate to that of the internal circumference of the pipeline 1. With this configuration, a polymer material is unlikely to be generated at the cover part 3 and around a gap 1b at an opening part 1a, and the frequency of cleaning can be reduced as compared to conventional cases.
