Description
【考案の詳細な説明】 （産業上の利用分野） 本考案は、自転車の前後輪のハブ軸の両端部を覆うキャ
ップに関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a cap that covers both ends of a hub axle of front and rear wheels of a bicycle.
（従来の技術） 第９図は従来の自転車の前輪用ハブ軸の支持部の一例を
示すもので、図中1Fは前輪用ハブ、2Fは前輪用ハブ軸、
３は前ホーク、3aはホーク爪、4,5は座金、6Fは前輪用
ハブ軸2Fと螺合する前輪用ナット、7Fはその前輪用ハブ
軸2Fの両端部にそれぞれかぶせた前輪用キャップであ
る。(Prior Art) FIG. 9 shows an example of a support portion of a conventional front wheel hub axle of a bicycle, in which 1F is a front wheel hub, 2F is a front wheel hub axle,
3 is a front hawk, 3a is a fork claw, 4 and 5 are washers, 6F is a front wheel nut that is screwed with the front wheel hub axle 2F, and 7F is a front wheel cap that is placed on both ends of the front wheel hub axle 2F. is there.
また6R（第６図参照）は後輪用ナットであり、前輪用ハ
ブ軸2Fに対して後輪用ハブ軸（図示せず）の径が若干大
きいため、後輪用ナット6Rも前輪用ナット6Fに対して、
ナットの陵線部までの半径が第６図のＬだけ大きい。6R (see FIG. 6) is a rear wheel nut. Since the diameter of the rear wheel hub shaft (not shown) is slightly larger than the front wheel hub shaft 2F, the rear wheel nut 6R is also a front wheel nut. For 6F,
The radius to the line of the nut is large by L in Fig. 6.
したがって従来は第７図（ａ）〜（ｄ）に示す前輪用キ
ャップ7Fは、第８図（ａ）〜（ｄ）に示す後輪用キャッ
プ7Rと大きさおよび形状が相違していた。Therefore, conventionally, the front wheel cap 7F shown in FIGS. 7 (a) to (d) is different in size and shape from the rear wheel cap 7R shown in FIGS. 8 (a) to (d).
（考案が解決しようとする課題） 上述のように従来の自転車用ハブ軸のキャップは、前輪
用と後輪用との２種類があったために、製造コストが嵩
む上に、部品管理が複雑になり、両者が混入したりする
結果、誤って使用し易くなる等の問題点があった。(Problems to be Solved by the Invention) As described above, there are two types of conventional bicycle hub axle caps, one for front wheels and one for rear wheels, which increases manufacturing costs and complicates parts management. As a result, both of them are mixed, and as a result, there is a problem that they are easily used by mistake.
（課題を解決するための手段） 上述の問題点を解決するため本考案においては、ハブナ
ットを圧入し得る角穴を形成すると共に、その角穴の各
辺の中間部に前記ハブナットより小型のハブナットの陵
線部を圧入し得る凹部を設けた筒体を略半球状のカバー
により外包したものを合成樹脂を素材として一体に形成
して自転車用ハブ軸のキャップを構成する。(Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, a square hole into which a hub nut can be press-fitted is formed, and a hub nut smaller than the hub nut is formed at an intermediate portion of each side of the square hole. The cap of the bicycle hub axle is formed by integrally forming a cylindrical body having a concave portion into which the ridge line portion can be press-fitted with a substantially hemispherical cover and using synthetic resin as a material.
（作用） 本考案のキャップは上述のように構成したから、径の大
きい後輪用ハブ軸に対しては、キャップに設けた角穴の
各角部にナットの各陵線部を整合して圧入すればよい。(Operation) Since the cap of the present invention is configured as described above, for the rear wheel hub axle having a large diameter, the root lines of the nuts are aligned with the corners of the square holes provided in the cap. Just press fit.
また径の小さい前輪用ハブ軸に対しては、キャップに設
けた角穴の各辺の中間部に設けた凹部にナットの各陵線
部を整合して圧入すればよい。Further, for the hub axle for the front wheel having a small diameter, it is sufficient to align and press-fit each root portion of the nut into a recess provided in an intermediate portion of each side of a square hole provided in the cap.
したがって本考案によれば、１種類のキャップを前後輪
用に共用することができる。Therefore, according to the present invention, one type of cap can be commonly used for the front and rear wheels.
（実施例） 以下、第１図〜第５図について本考案の一実施例を説明
する。図中前記符号と同一の符号は同等のものを示す。(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. In the figure, the same reference numerals as those used in the previous description denote the same elements.
本実施例においては、後輪用ハブナット6Rを圧入し得る
角穴８を形成すると共に、その角穴８の各辺8aの中間部

線部6aを圧入し得る凹部９を設けた筒体10を略半球状の
カバー11により外包したものを合成樹脂を素材として一
体に形成して自転車用ハブ軸のキャップ12を構成する。In this embodiment, the square hole 8 into which the rear wheel hub nut 6R can be press-fitted is formed, and the peak portion 6a of the front wheel hub nut 6F smaller than the hub nut 6R is formed in the middle portion of each side 8a of the square hole 8. A bicycle hub axle cap 12 is formed by integrally forming a cylindrical body 10 provided with a concave portion 9 into which is fitted with a substantially hemispherical cover 11 with synthetic resin as a material.
なお13はカバー11の端縁部の外周面において、前記各凹
部９と対応する位置にそれぞれ突設した目印用の突起で
ある。Reference numeral 13 is a protrusion for marking, which is provided on the outer peripheral surface of the edge of the cover 11 at a position corresponding to each of the recesses 9.
本考案のキャップ12は上述のように構成したから、径の
