If comprised in this way, the rigidity around the shaft holes 21h and 22h can be raised.
As a result, the outer plate 21 and the inner plate 22 can be formed thin, and the rear end of the rear fork 10 can be further reduced.

外プレート２１の凹部２１ｃの前方には、車幅方向外側へ膨出する前部膨出部２１ｆが設けられ、この前部膨出部２１ｆに溝２１ｄが設けられている。そしてこの溝２１ｄに、アジャストボルト４１（図３参照）用のナット２６が埋設され固着されている。   A front bulging portion 21f that bulges outward in the vehicle width direction is provided in front of the concave portion 21c of the outer plate 21, and a groove 21d is provided in the front bulging portion 21f. A nut 26 for the adjusting bolt 41 (see FIG. 3) is buried and fixed in the groove 21d.

このように構成すると、簡単な構成でアジャストボルト用のナット２６を固定することができる。   If comprised in this way, the nut 26 for adjustment bolts can be fixed with a simple structure.

図３（ａ）に示すように、補強プレート２５の外径Ｄ２は、軸孔２１ｈ、２２ｈに貫通される後車軸３０をなすボルトの頭部３１の座面３２および、ボルト３０に螺合されるナット３３の座面３４の外径Ｄ１よりも大きい。
このように構成すると、ボルト３０とナット３３とで締め上げられる座面３２，３４の受部の剛性を上げることができる。 As shown in FIG. 3 (a), the outer diameter D2 of the reinforcing plate 25 is screwed into the bolt 30 and the seat surface 32 of the bolt head portion 31 forming the rear axle 30 that passes through the shaft holes 21h and 22h. The outer diameter D1 of the seat surface 34 of the nut 33 is larger.
If comprised in this way, the rigidity of the receiving part of the seat surfaces 32 and 34 tightened with the volt | bolt 30 and the nut 33 can be raised.

図１に示したリヤフォーク１０は、その前部のパイプ部１２が、図示しない車体にピボットで上下揺動可能に支持される。リヤフォーク１０を形成する角パイプ１１は鉄系合金、アルミ系合金のいずれでも構成することができる。   The rear fork 10 shown in FIG. 1 has a front pipe portion 12 supported on a vehicle body (not shown) so as to be swingable up and down by a pivot. The square pipe 11 forming the rear fork 10 can be composed of either an iron-based alloy or an aluminum-based alloy.

エンドピース２０を構成する各部材も、鉄系合金、アルミ系合金のいずれでも構成することができる。
外プレート２１、内プレート２２は、いずれも、薄板のプレスにて成型する。
外プレート２１、内プレート２２の周縁２１e、２２e同士は溶接にて接合する。 Each member constituting the end piece 20 can also be made of either an iron-based alloy or an aluminum-based alloy.
Both the outer plate 21 and the inner plate 22 are molded by a thin plate press.
The peripheral edges 21e and 22e of the outer plate 21 and the inner plate 22 are joined together by welding.

補強プレート２５は、外プレート２１と内プレート２２との溶接に先立って、内プレート２２の内面に溶接しておく。
アジャストボルト４１用のナット２６は、外プレート２１の前部膨出部２１ｆの溝２１ｄに嵌め合わせて溶接にて固着する。 The reinforcing plate 25 is welded to the inner surface of the inner plate 22 prior to the welding of the outer plate 21 and the inner plate 22.
The nut 26 for the adjustment bolt 41 is fitted into the groove 21d of the front bulging portion 21f of the outer plate 21 and fixed by welding.

以上のようなエンドピース２０は、その前部をリアフォークの角パイプ１１の後部に溶接することによって、角パイプ１１の後部に固着される。図１〜図３において、溶接部を符号１３で示す。   The end piece 20 as described above is fixed to the rear part of the square pipe 11 by welding its front part to the rear part of the square pipe 11 of the rear fork. In FIG. 1 to FIG.

なお、アジャストボルト４１用のナット２６は、エンドピース２０を角パイプ１１の後部に溶接する際に同時に溶接するようにしてもよい。
ナット２６の角パイプ１１への溶接部２６ｃは、平面状に形成されている。 The nut 26 for the adjustment bolt 41 may be welded simultaneously when the end piece 20 is welded to the rear portion of the square pipe 11.
The welded portion 26c of the nut 26 to the square pipe 11 is formed in a planar shape.

図３に示すように、ナット２６には、アジャストボルト４１が取り付けられる。後車軸３０は車両前後方向にスライド可能なチェンテンショナー４２に挿入されており、このチェンテンショナー４２の位置をアジャストボルト４１で調整することで、後車軸３０の位置調整（したがって、チェンの張り具合の調整）が可能である。   As shown in FIG. 3, an adjustment bolt 41 is attached to the nut 26. The rear axle 30 is inserted into a chain tensioner 42 slidable in the longitudinal direction of the vehicle. By adjusting the position of the chain tensioner 42 with an adjustment bolt 41, the position of the rear axle 30 can be adjusted (therefore, the tension of the chain). Adjustment) is possible.

以上、本発明の実施の形態について説明したが、本発明は上記の実施の形態に限定されるものではなく、本発明の要旨の範囲内において適宜変形実施可能である。
例えば、図示の内プレート２２は周縁２２eを立ち上げ形成した形状となっているが、内プレート２２は周縁２２eを立ち上げない平板状とすることもできる。
そのように内プレート２２を平板状としても、外プレート２１と内プレート２２との周縁２１ｅ、２２ｅ同士を接合して内部２３を中空とすることが可能である。 Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be appropriately modified within the scope of the gist of the present invention.
For example, although the illustrated inner plate 22 has a shape in which the peripheral edge 22e is raised, the inner plate 22 may have a flat plate shape that does not raise the peripheral edge 22e.
Even if the inner plate 22 has a flat plate shape as described above, the inner periphery 23 can be made hollow by joining the peripheral edges 21e of the outer plate 21 and the inner plate 22 together.
