Abstract
A grommet used in an automobile reduces noise leakage from the engine compartment to the passenger compartment. It is made of rubber or an elastomer, and it includes a small tube portion, through which a wiring harness is passed, a frustoconical tube portion flaring from an edge of the small tube portion and a flared portion, on the outer surface of which is formed a recess for fitting into a body panel. An internal tube portion through which the wiring harness is passed extends axially from the small tube portion in the frustoconical tube portion, and a closing portion is connected to the flared portion and to the edge of the internal tube portion distal to the edge of the small tube portion.
