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 partis formed to have a curved surfaceon a side closer to inside of a pipeline. The shape of the surfaceon the pipelineside is preferably a concave shape when viewed from inside of the pipeline. The shape of the surfaceof the cover parton the pipelineside 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. With this configuration, a polymer material is unlikely to be generated at the cover partand around a gapat an opening part, and the frequency of cleaning can be reduced as compared to conventional cases.
