Grommet for preventing water penetration
A synthetic resin grommet is provided which has a substantially cylindrical body having a flange portion and a head portion. The flange portion has an inverted dish-like shape and includes an elastically deformable vane-like shaped rim portion. Stopping claws are arranged on an outer circumference of the cylindrical body such that tips of the claws face the flange portion, and an elastically compressible annular rib is formed on top of the head portion of the cylindrical body. An upper portion of the head portion has a tapered face, and the annular rib is formed above the tapered face. With this structure, an inexpensive synthetic resin grommet is provided which exhibits sealing facility when it is fitted to a body of a car or a home electric appliance and when a part is attached thereto through the grommet, and which accurately and securely prevents the entrance of water into the body without requiring intricate procedures such a fitting of a sealing annulus.
