Abstract:
A rubber plug assembly (40) includes a rubber plug (50) with a shaft (51) and waterproofs the interior of a housing (20). Legs (52) extend out in a radial direction from an axial end (51A) of the shaft (51). Recesses are in the legs (52) and are long in the radial direction. A cover (70) is to be fixed to the housing (20). A rubber plug holder (60) includes assembling holes (65) for allowing the legs (52) oriented in an axial direction to be inserted therein by resiliently deforming parts of the legs (52) and projections (66) for positioning the rubber plug (50) by being fit into the recesses as the legs (52) that have passed through the assembling holes (65) return. The projections (66) and the recesses are held in a fit state by fixing the rubber plug holder (60) to the cover (70).
