A rubber stopper assembly 40 is provided with: a rubber stopper 50 that has a shaft 51, which cuts off water from inside a housing 20, and is provided with a leg 52 that extends outward in the radial direction from an axial-direction end 51A of the shaft 51 and has a recess having a long shape in the radial direction; a cover 70 fixed to the housing 20; and a rubber stopper holder 60 that has an assembly hole 65, is provided with a protrusion 66, and, when fixed to the cover 70, is held in a state in which the protrusion 66 is fitted to the recess. When a portion of the leg 52 is elastically deformed, the leg 52, oriented so as to extend in the axial direction, is inserted through the assembly hole 65. When the leg 52 passing through the assembly hole 65 returns to the original position, the protrusion 66 is fitted to the recess and positions the rubber stopper 50. |
