DICHTUNGSTÜLLE MIT GESCHLOSSENEM LUFTINNENRAUM

摘要

A grommet (1) including a first tubular potion (33) holding an electric wire (10) therein; an elastic first flange (34) formed on a front part of the first tubular portion (33); a second tubular portion (31) which extends rearward from the first flange (34) and is to be fitted in a panel hole (21) when the first tubular portion (33) is pulled frontward; a rib portion (39) annularly formed on the second tubular portion (31); and an elastic second flange (35) formed on a rear part of the first tubular portion (33), which diverges rearward. Cooperating with the first tubular portion (33) and the first flange (34), the second tubular portion (31) defines an annular space (37), and an entrance thereof is defined by the rib portion (39). The second flange (35) extends in a radial direction outside the entrance of the annular space (37).
