ものである。[Detailed Description of the Invention] [Industrial application field and outline of the invention] The present invention relates to a wheel mounting structure for a bicycle, and in particular, a claw portion for supporting a wheel due to repeated impact force or vibration. The present invention relates to a wheel mounting structure for a bicycle, which prevents the hub axle from moving toward the open end side of the claw portion even when the clamping force acting on the hub from the above is reduced.
［従来技術とその問題点及び課題］ 自転車の車輪は、フレーム及び前ホークにおける一対
の車輪支持用のツメ部にハブを挟持する態様で取付けら

トで締付けるようにして固定してある。[Prior Art and Problems and Problems Thereof] A bicycle wheel is attached in such a manner that a hub is sandwiched between a pair of wheel-supporting claw portions of a frame and a front hawk. It is fixed by tightening with a screwed nut.
他方、ロードレース用の自転車では、工具を使用しな
いで簡単に車輪が着脱できるようにする為、クイックレ
リーズハブを採用している。On the other hand, bicycles for road racing use quick release hubs so that the wheels can be easily attached and removed without the use of tools.
このクイックレリーズハブは、第５図に示すように、
中空のハブ軸（44）内に挿通したロッド（42）の一端に
調整ナット（40）を螺合すると共に他端にカム機構部を
介して操作レバー（41）と連動する締付具（43）を具備

メ部（Ｔ），（Ｔ）間にハブを挟持させるものである。This quick release hub, as shown in Fig. 5,
A tightening tool (43) that engages an adjusting nut (40) with one end of a rod (42) inserted into a hollow hub shaft (44) and that interlocks with the operating lever (41) at the other end via a cam mechanism. ) Is provided, the tightening tool (43) is moved back and forth with respect to the rod (42) by the turning operation of the operation lever (41), and the adjusting nut (40) and the tightening tool (43) are tightened. The hub is clamped between the claws (T) and (T) by force.
ところが、上記クイックレリーズハブを採用したもの

ブ軸（44）はツメ部（Ｔ）の開放端側へ相対移動可能な
状態となって、非常に危険となる。However, in the case where the quick release hub is adopted, since the clamping force is applied by the cam mechanism, it is easier to loosen as compared with the screw-fastening method, and the tightening tool (43 ) Is loosened, the clamping force acting on the hub from the claw (T) is extremely reduced, and the hub shaft (44) is relatively movable to the open end side of the claw (T). Very dangerous.
そこで、上記問題を解決する為、従来は、第５図及び
第６図に示すように、外周部に折曲片（38）を具備させ

3）との間に、それぞれ介在させている。Therefore, in order to solve the above problem, conventionally, as shown in FIGS. 5 and 6, a hub is provided with a ring-shaped locking metal fitting (3) having a bent piece (38) on the outer peripheral portion. In such a manner that the bent piece (38) is fitted onto the shaft (44) and the bent piece (38) is fitted into the engaging hole (20) provided at the base end of the tab (T), the tab (T) and the adjusting nut ( 40) and between the tab (T) and the fastener (4
It is interposed between 3) and each.

放端側への移動が阻止されることとなり、上記した危険
は回避される。In this case, even if the fastening tool (43) is loosened and the clamping force acting on the hub (4) from the claw portion (T) is reduced, the bending piece (38)
Since the engaging hole and the engaging hole (20) are in an engaged state, the hub shaft (44) is prevented from moving toward the open end side of the claw portion (T) by the locking metal fitting (3). Therefore, the above danger is avoided.
しかしながら、上記の構造のものでは、ツメ部（Ｔ）

しく低下してしまうと言う問題がある。However, with the above structure, the claw portion (T)
Since it is necessary to provide the engaging hole (20) in the bicycle, there is a problem that the strength of this portion is reduced and, as a result, the safety of the bicycle is significantly reduced.
本考案はかかる点に鑑みてなされたものであり、ツメ

より、自転車としての安全性を向上ならしめるようにす
ることを、その課題とする。The present invention has been made in view of the above point, and the hub shaft (44) is located on the opening side of the claw (T) even if the clamping force acting on the hub (4) from the claw (T) is reduced. Even when adopting a bicycle wheel mounting structure that does not move, it is an issue to ensure that the strength of the claws can be sufficiently secured, thereby improving the safety of the bicycle. To do.
［技術的手段］ 上記課題を解決する為に講じた本考案の技術的手段

から脱出するようにした』ことである。[Technical Means] The technical means of the present invention taken to solve the above-mentioned problem is to "tighten the tightening bodies (5) provided at both ends of the hub shaft (44) in directions toward each other. A wheel mounting structure in which the tightening body (5) is brought into pressure contact with the outer surfaces of a pair of wheel supporting claws (T), whereby a hub is sandwiched between the claws (T), (T). In addition, a recessed portion (50) is provided on the inner surface side of the tightening body (5) and a protrusion is provided on the outer surface side of the claw portion (T) so that the tightening body (5) contacts the claw portion (T). When in contact with each other, the protrusions penetrate into the recesses (50), and the protrusions and recesses (50) engage in a direction that prevents the hub shaft from moving toward the claw open end side, and the tightening is performed. In a state where the attachment body (5) is separated from the claw portion (T) to the wheel removal position, the above-mentioned protrusion is the recessed portion (50).
I tried to escape from that. "
［作用］ 上記技術的手段は次のように作用する。[Operation] The above technical means operates as follows.

（５）の凹陥部（50）に侵入した状態が確保されている
限り、ハブ軸（44）がツメ部（Ｔ），ツメ部（Ｔ）の開
放端側へ移動しない。When the tightening body (5) is in contact with the claw (T), the projection provided on the claw (T) penetrates into the recess (50) of the tightening body (5) and both It is in the engaged state. Therefore, even if the pressing force acting from the tightening body (5) to the claw portion (T) is reduced and the clamping force acting from the claw portion (T) to the hub is reduced, the tip portion of the protrusion is tightened. The hub axle (44) does not move to the claw portion (T) and the open end side of the claw portion (T) as long as the state of entering the concave portion (50) of the body (5) is ensured.
又、締付体（５）をツメ部（Ｔ）から車輪取り外し位

されることとなる。Even when the gripping force acting on the hub (4) from the claw portion (T) decreases, the hub shaft (44) does not move to the open end side of the claw portion (T), so that the wheel is The danger of falling off the front hawk or the frame will certainly be avoided.
そして、ツメ部（Ｔ）には係合孔は形成されないもの
となるから、ツメ部（Ｔ）の強度は十分に確保されるこ
ととなり、自転車としての安全性は優れたものとなる。Further, since the engaging hole is not formed in the claw part (T), the strength of the claw part (T) is sufficiently secured, and the safety as a bicycle is excellent.
