Description

本発明は、内燃機関の燃料をろ過するフューエルフィルタに関する。   The present invention relates to a fuel filter for filtering fuel of an internal combustion engine.

（ａ） 特開平７−５４７２８号公報は、本体とキャップをファスナーリングで締結する構造を備えるフューエルフィルタであって、ねじ部の上側で互いに対向するキャップ側軸方向対向部と本体側軸方向対向部を備えたフューエルフィルタを開示している。
（ｂ） 特開２００１−３１７４２７号公報は、本体とキャップを直接締結する構造を備えるフューエルフィルタであって、ねじ部の上側で互いに対向するキャップ側軸方向対向部と本体側軸方向対向部を備えたフューエルフィルタを開示している。
（ｃ） 特開２０００−１１０５３７号公報は、本体とキャップをセンターボルトで締結するフューエルフィルタであって、シール部の上側で互いに対向するキャップ側軸方向対向部と本体側軸方向対向部を備えたフューエルフィルタを開示している。 (A) Japanese Patent Application Laid-Open No. 7-5472 8 is a fuel filter having a structure in which a main body and a cap are fastened with a fastener ring, and a cap side axial facing portion and a main body side axial direction that face each other on the upper side of a threaded portion. A fuel filter having a facing portion is disclosed.
(B) Japanese Patent Application Laid-Open No. 2001-317427 is a fuel filter having a structure in which a main body and a cap are directly fastened, and includes a cap side axial facing portion and a main body side axial facing portion facing each other on the upper side of a threaded portion. A fuel filter provided is disclosed.
(C) Japanese Patent Application Laid-Open No. 2000-110537 is a fuel filter for fastening a main body and a cap with a center bolt, and includes a cap side axial facing portion and a main body side axial facing portion facing each other on the upper side of the seal portion. A fuel filter is disclosed.

しかし、従来のフューエルフィルタには、つぎの問題点がある。
キャップ側軸方向対向部の外径が本体側軸方向対向部の外径と同じか本体側軸方向対向部の外径より小径になっている。そのため、水溜り路などを走行した時にフューエルフィルタにかかった泥水等が両対向部間からフューエルフィルタ内に入り込みやすい。フューエルフィルタ内に入り込んだ泥水等がネジ部やシール部に侵入して乾燥すると、キャップを本体から取り外すのが困難になる。
特開平７−５４７２８号公報 特開２００１−３１７４２７号公報 特開２０００−１１０５３７号公報 However, the conventional fuel filter has the following problems.
The outer diameter of the cap side axial facing portion is the same as the outer diameter of the main body side axial facing portion or smaller than the outer diameter of the main body side axial facing portion. Therefore, muddy water or the like applied to the fuel filter when traveling on a water reservoir or the like tends to enter the fuel filter from between the opposing portions. When muddy water or the like that has entered the fuel filter enters the screw portion or the seal portion and is dried, it is difficult to remove the cap from the main body.
