A rubber plug (40) is provided with a stable sealing property while reducing frictional resistance when the rubber plug (40) is inserted into a cavity. In a cross section including axis lines of the rubber plug (40), a cavity (11) and a wire (30), areas of outer lips (44A, 44B) not resiliently defor

A rubber plug (40) is provided with a stable sealing property while reducing frictional resistance when the rubber plug (40) is inserted into a cavity. In a cross section including axis lines of the rubber plug (40), a cavity (11) and a wire (30), areas of outer lips (44A, 44B) not resiliently deformed radially outward of a virtual line (12L) corresponding to the inner circumferential surface of the cavity (11) are specified as outer virtual deforming portions (45A, 45B), areas of inner lips (46A, 46B and 46C) not resiliently deformed radially inward of a virtual line (31L) corresponding to the outer circumferential surface of the wire (30) are specified as inner virtual deforming portions (47A, 47B, and 47C) and at least parts of the inner virtual deforming portions (47A, 47B and 47C) correspond to only parts of the outer virtual deforming portions (45A, 45B).

What is claimed is: 1. A resilient plug to be mounted on a wire connected with a portion of a terminal fitting and to be at least partly inserted into a cavity of a housing together with the terminal fitting, the cavity having an inner circumferential surface, the resilient plug comprising:a plurality of outer lips to be held in close contact with the inner circumferential surface of the cavity while being resiliently deformed and a plurality of inner lips to be held in close contact with an outer circumferential surface of the wire while being resiliently deformed;outer virtual deforming portions being defined by areas of each of the outer lips not resiliently deformed radially outward of a virtual line corresponding to the inner circumferential surface of the cavity in a cross section including axis lines of the resilient plug and the cavity;inner virtual deforming portions being defined by areas of each of the inner lips not resiliently deformed radially inward of a virtual line corresponding to the outer circumferential surface of the wire in an undeformed state in the cross section including axis lines of the resilient plug and the wire; andat least a part of each of the inner virtual deforming portions being arranged to correspond to only a part of any one of the outer virtual deforming portion in a longitudinal direction and at least one of the inner virtual deforming portions being arranged to correspond to parts of two of the outer virtual deforming portions.
