A steam trap comprising:
- a body including an inlet and an outlet, and formed with a flow path between the inlet and the outlet;
- an opening/closing unit installed in the outlet of the body and configured to open and close the flow path;
- an operating unit installed on the flow path, and configured to operate the opening/closing unit by bellows being expanded or contracted by heat;
- and
- an pressing unit for pressing the opening/closing member toward a nozzle,
- wherein the opening/closing unit is formed with at least one or more discharge holes and includes the nozzle configured to close a side of the outlet of the flow path outside of the discharge holes, a through hole connected to the discharge hole when the opening/closing unit performs an opening operation, an opening/closing member configured to close or open the discharge hole while moving in a straight line in close contact with the nozzle, and an operation rod connecting bellows of the operation unit and the opening/closing member and transmitting a force of contraction or expansion of the bellows configured to move the opening/closing member in a straight line to the opening/closing member, and
- wherein the pressing unit includes:
- a support member that is spaced apart from the opening/closing member toward the inlet and is arranged across the flow path;
- a pressing member provided between the support member and the opening/closing member and pressing the opening/closing member toward the nozzle;
- and
- a guide portion for guiding the pressing member to slide on the support member or the opening/closing member.
