HOLE PLUG

摘要

In a hole plug, shaft bearing portions that axially support a shaft section of a flap valve are formed to an upper portion of an upright wall portion of a panel configuring a housing. The shaft bearing portions are positioned above a groove portion of an engagement section that acts as a contact portion with an opening hole of a floor panel, and are positioned above a lower end edge of a resilient engagement portion.

主权项

1. A hole plug comprising:
a housing capable of internally accumulating water that has entered through a water entry port; an engagement section that is provided at the housing, that is configured to be inserted through an opening hole of an attached-to member, and that engages with a peripheral edge portion of the opening hole; a water discharge port that is formed in the housing to discharge water that has accumulated inside the housing; a shaft bearing portion formed at a location on the housing positioned above a contact portion of the engagement section with the opening hole; a valve body that includes a shaft portion axially supported by the shaft bearing portion so as to be capable of rotating, and that is capable of swinging between an open position opening the water discharge port and a closed position closing off the water discharge port; and a biasing member that is provided at the shaft portion in order to swing the valve body in the closed position direction using biasing force, and to swing the valve body in the open position direction when water pressure inside the housing is greater than the biasing force.
