The purpose of the present invention is to provide a steam trap equipped with a cleaning mechanism capable of shortening the time necessary for drainage discharge actions when starting operation. The steam trap (1) is equipped with: a casing (10) with a small diameter section (16a), which is a drainage discharge port; a bimetal (22), which is provided at a position through which the drainage discharged from the small diameter section (16a) flows and which is displaced due to temperature changes; and a rod-shaped cleaning member (30) for removing foreign matter in the small diameter section (16a) by advancing and retracting from the outside of the small diameter section (16a) as a result of displacement of the bimetal (22). The proportion of the cross-sectional area (A1) of the portion of the cleaning member (30) that enters into the small diameter section (16a) with respect to the area (A2) of the opening of the small diameter section (16a) is 0.3 to 0.8. |
