【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、自動車等のパネル貫通孔に挿通される電線
を保護すると共に該孔を密閉するために用いられるグロ
メットに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a grommet used to protect an electric wire inserted into a panel through hole of an automobile and to seal the hole.
パネル貫通穴に弾性的に密着嵌合し且つ電線を挿通定
着させる為のグロメットは、パネル貫通孔に対する圧入
嵌合が容易であると共に確実なシール性能を具備するこ
とが品質上求められている。A grommet for elastically tightly fitting into a panel through hole and inserting and fixing an electric wire is required in terms of quality so that it can be easily press-fitted into a panel through hole and has a reliable sealing performance.
ところで、第４図及び第５図に示される長円状の環状

貫通孔ｄに取り付けた状態において、長円形状が短径方
向の内側にくびれ変形する所謂撓みを生じ易く、これに
よってシール性能が低下すると共に取り付けが不安定と
なる欠点がある。By the way, in the grommet a having the oval annular mounting groove b shown in FIGS. 4 and 5, when the grommet a is attached to the through hole d of the panel c, the oval shape is the inner side in the minor axis direction. There is a drawback in that so-called bending, which is constricted and deformed, tends to occur, which lowers the sealing performance and makes the mounting unstable.

を低下させる。On the other hand, in the oval grommet a'shown in FIGS. 6 and 7, the reinforcing support portion e is provided in the minor axis direction of the inner cavity in order to prevent such constriction deformation. When the grommet a'is attached to the panel through hole d, the reinforcing support portion e resists the flexible deformation of the annular attachment groove b portion, which becomes an obstruction factor for press-fitting and reduces the efficiency of the attachment work.

方には衝合鍔部５が形成されている。In FIG. 1 and FIG. 2, A is a grommet made of a relatively soft rubber material, and has a large-diameter oval mounting cylinder portion 1 and two small-diameter wire insertion cylinder portions 2. Oval mounting cylinder 1
A U-shaped annular mounting groove 3 is formed in the middle of the outer peripheral portion of the, and a deformation-permitting collar 4 having a tapered fitting guide surface 4a is formed in front of the annular mounting groove 3 in the fitting direction. An abutment collar portion 5 is formed behind the abutting direction.
