Zusammenfassung:	Provided is a housing and a rubber plug of a power conversion equipment, the housing is provided with a plurality of service holes at a surface thereof, and the service holes are used for electrical connection of circuits inside the housing of the power conversion equipment. The rubber plug (2) for closing each service hole (3) has a cylindrical seal surface (7) to be fitted in the service hole (3), and a flange (4) to be brought into contact with an outer surface of the housing (1). The rubber plug (2) has a cylindrical cup-shaped cored bar (5) inside. The cored bar (5) has a disc-shaped flange-portion cored bar (5a), outside the housing (1), which is greater in a radial direction than a cylindrical portion of the service hole (3). The cored bar (5) has a convex portion (8a) in a cylindrical-cup bottom (8) of a recess (17), of the rubber plug (2), which is formed inward of the housing (1). The convex portion (8a) is coaxial with the cylindrical seal surface (7) and projects toward an outward direction of the housing (1). A lip seal (6) to be brought into contact with the housing (1) is provided at a surface of the flange (4).
