The present invention relates to an inner diameter-adjustable drain trap, of which an inner diameter can be expanded or contracted simply by horizontally moving an inner diameter adjusting member with a handle, according to the diameter of a drain hose for a washing machine, and a space is not formed between the drain hose and the drain trap, thereby safely draining water from the drain hose to a drain hole, and thus preventing the water from leaking or noise and bad smell from being produced. An inner diameter-adjustable drain trap according to an embodiment of the present invention includes an elbow pipe body having one end inserted in a drain pipe and the other end receiving a drain hose; a coupling ring member connected to the other end of the elbow pipe body and having a guide rail (21) at one side and a through-slit at the other side; and an inner diameter adjusting member having a width gradually widened from one side to the other side, and having a handle protruding from a lateral portion. An outer edge of the inner diameter adjusting member is inserted in the guide rail to be able to horizontally move, and the handle is exposed outwardly through the through-slit. The inner diameter adjusting member is slid along the guide rail by an adjusting direction of the handle, so that the inner diameter of the elbow pipe body is expanded or contracted together with the guide rail. |
