【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、車両のオイルパン等へオイルを供給するオ
イルフィラー管の構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a structure of an oil filler pipe for supplying oil to an oil pan or the like of a vehicle.
車両のエンジンのオイルパン等には、その中にオイル
を供給するオイルフィラー管が設けられている。2. Description of the Related Art An oil pan or the like of a vehicle engine is provided with an oil filler pipe for supplying oil therein.

受け皿３が設けられた構造になっている。For example, an oil filler tube as shown in FIGS. 2 and 3 is provided in an oil pan of a bath. The oil filler pipe has a structure in which a tip injection port 2 having an enlarged diameter and a tray 3 for receiving oil spilled at the time of injection are provided at the tip of a filler pipe main body 1 having the same diameter.

である。However, the oil filler tube is located at the tip injection port 2.
When oil is supplied by using an oil mug 5 as shown in FIG. 4, the inlet end 6 of the oil mug 5 comes into contact with the step 4 of the inlet 2 of the oil filler pipe. Oil may accumulate in the step portion 4, or some of the oil may leak to the outside of the tip inlet portion 2. The oil leaked outside is received by the receiving tray 3 and dropped to the ground through the guide pipe 7, but the oil leaked outside is discharged from the oil filler pipe 1 and the tip inlet 2.
There is a danger that it will be mistaken for oil leakage since the trace will remain after penetrating into the welded portion 8. Further, since the oil filler tube is formed by forming the filler tube main body 1 and the front end injection port portion 2 from sheet metal and welding the two, the processing is complicated.

次拡径することは、加工上非常に難しい。In view of the above, for example, the one disclosed in Japanese Utility Model Laid-Open Publication No. 62-135809 has been proposed, but the oil filler pipe is sealed by a method in which a cap sandwiches a flange provided at a tip inlet. Therefore, the reliability of the seal is slightly lacked. In forming a sheet metal oil filler tube, it is very difficult in processing to gradually increase the diameter toward the tip injection port.

る。The present invention has been made in view of the above, and the purpose thereof is to prevent oil from being mistakenly interpreted as an oil leak by eliminating oil leakage at the tip inlet port at the time of refueling and eliminating oil leakage in the middle of the pipe. Another object of the present invention is to provide an oil filler tube structure which improves sealing performance and facilitates processing.

を特徴とする。In order to achieve the above object, the present invention is to form a tip injection port and a filler pipe body integrally with a casting, and to make the tip injection port a thick-walled part having an enlarged diameter, the tip injection port and a filler pipe. It is characterized in that the boundary with the main body is formed to have a maximum thickness, and the inner diameter is gradually reduced from the tip inlet to the filler tube main body, and a cap is screwed onto the tip inlet.
先端注入口部からオイルを注入すれば、それほど注意
せずとも拡径した先端注入口部から漸次縮径したフィラ
ー管本体へ自然に円滑に流れオイルフィラー管途中で溜
まらなくなる。If the oil is injected from the tip injection port, the oil flows naturally smoothly from the enlarged tip injection port to the gradually reduced diameter filler pipe body without much care, and does not accumulate in the middle of the oil filler pipe.
また拡径した厚肉部になった先端注入口部にキャップ

部の剛性が高まり、強度的に強くなる。Furthermore, since the boundary between the tip injection port and the filler tube main body where the stress tends to be concentrated is the thickest part, the rigidity of the boundary is increased and the strength is increased.
以下、図面により本考案を詳細に説明する。 Hereinafter, the present invention will be described in detail with reference to the drawings.
第１図は、本考案に係るオイルフィラー管構造の一実

ている。In the figure, reference numeral 10 denotes a filler tube main body provided with a tip inlet 11 at its tip. The filler tube main body 10 and the tip inlet 11 are integrally formed of a casting (for example, aluminum). The filler tube main body 10 is formed of a tube having the same inner diameter 12. On the other hand, the tip inlet 11 has a thickened portion 13 whose diameter is enlarged, and the tip inlet 11 and the filler tube body 10
In addition to the maximum thickness of the boundary portion 18, the inner diameter 14 is gradually reduced from the tip inlet 11 to the filler tube main body 10. A screw 15 is cut in the thick tip injection port portion 11 and a cap 16 is screwed thereto, while an oil filler tube is attached to the oil pan at the other end of the filler tube body 10. Flange portion 17 is provided integrally.

厚肉部13からなる先端注入口部11にキャップ16を螺着す
るので、シール性は確実になる。According to such an oil filler tube, the inner diameter 14 extends from the enlarged tip inlet portion 11 to the filler tube body 10.
Is gradually reduced in diameter, so that it flows smoothly from the tip injection port 11 to the filler tube main body 10 during injection. Of course, since there is no step inside the tip inlet 11, oil does not accumulate on the way. Therefore, there is no leakage of the tip inlet 11 to the outside. Therefore, it is also possible to avoid misunderstanding that oil is leaking due to the evidence of external leakage at the time of injection. Filler tube body 10
Further, since the tip inlet 11 is formed by integral molding of an aluminum casting, the processing is extremely easy. In addition, since the cap 16 is screwed into the tip injection port 11 composed of the thickened portion 13 having an increased diameter, the sealing performance is ensured.
上記実施例においては、フィラー管本体10がほぼ
「く」の字状に曲がった管になっているが、フィラー管
本体10の形状はレーアウトの関係等からその取付場所に
応じた適切な形状を選ぶことが望ましい。In the above embodiment, the filler tube main body 10 is a tube bent substantially in the shape of the letter `` C '', but the shape of the filler tube main body 10 has an appropriate shape according to the mounting location from the relationship of layout and the like. It is desirable to choose.

もシール性の向上及び加工の容易性を図ることができ
る。As described above, according to the present invention, there is no oil pool in the middle of the pipe, and it is possible to prevent the leakage from the outside of the inlet portion at the time of refueling to be misunderstood as an oil leak. Ease of processing can be achieved.
また、先端注入口部とフィラー管本体との応力が集中
