に対するリンク32の連結部である。The lower end portion of the shock absorber 34 is connected to the rear fork 36 assembled with such a structure via the links 30 and 32 (FIG. 3). In the link 30, the bolt 88 and the nut 90 are inserted through the round holes 42 and 46 of the arm 38 and the round holes 54 and 58 of the arm 50, and the side wall.
A bolt 88 is passed through the round holes 78, 78 and the triangular link 30 of 76, and the bolt 88 and the nut 90 are screwed together to be connected to the lateral connecting member 62. The nut 90 may be welded to the outer surface of the side wall 76 in advance. In FIG. 3, point C is the connecting portion of the link 30 to the horizontal connecting member 62,
Point D is a connecting portion of the link 30 and the link 32, point E is a connecting portion of the shock absorber 34 to the link 30, and point F is a connecting portion of the link 32 to the vehicle body frame side protrusion.

するとリンク30は矢印Ｇ方向へ、リンク32は矢印Ｈ方向
へそれぞれ揺動し、緩衝装置34は短縮する。本実施例の
リヤフォーク36を採用することによる作用効果は下記の
通りである。According to such a connecting mechanism of the shock absorber 34 to the rear fork 36, when the rear fork 36 swings upward in FIG. 3, the link 30 swings in the arrow G direction and the link 32 swings in the arrow H direction. The shock absorber 34 is shortened. The effects obtained by adopting the rear fork 36 of this embodiment are as follows.
横連結部材62に対するリンク30の連結箇所の上方ない

泥避け片をリヤフォーク36に取着する必要がない。それ
故、部品点数の削除、組立作業能率の向上、リヤフォー
クの軽量化を計り得る。Since the top wall 72 and the back wall 74 of the main body portion 68 are located above or behind the connecting portion of the link 30 to the lateral connecting member 62, the earth and sand, mud, and water splashed from the rear wheel RW are lateral connecting member 62, the link. It is not necessary to attach a separate mud-preventing piece to the rear fork 36 without directly connecting the connecting portions of the 30, 32 and the shock absorber 34. Therefore, it is possible to reduce the number of parts, improve the assembly work efficiency, and reduce the weight of the rear fork.
横連結部材62に対するリンク30の連結点Ｃが腕38，50
の側壁40，52で挟まれた部位にあるため、リンク30，32
および緩衝装置34の下端部がリヤフォーク36の下方へ大
きく突出せず、多少とも車高を低く設定することが可能
である。The connecting point C of the link 30 to the lateral connecting member 62 is the arm 38, 50.
Since it is located between the side walls 40 and 52 of the
Also, the lower end portion of the shock absorber 34 does not largely project below the rear fork 36, and the vehicle height can be set to be somewhat low.
リヤフォーク36の上面にリンク連結部分が突出してい
ないため、リヤフォーク36の揺動範囲を考慮しつつ、空
気清浄器92の底壁部をリヤフォーク36に十分接近させる
ことができ、リヤフォーク36の上位に配置される空気清
浄器92の容量を十分大きく確保し得るとともに、空気清
浄器92の配置上の自由度が大である。Since the link connecting portion does not project on the upper surface of the rear fork 36, the bottom wall portion of the air purifier 92 can be sufficiently brought close to the rear fork 36 while considering the swing range of the rear fork 36. It is possible to secure a sufficiently large capacity of the air purifier 92 arranged in the higher order of the above, and the degree of freedom in arrangement of the air purifier 92 is great.
その頂壁72，背壁74がＬ字形断面形状になされるとと
もに、中空の内部に隔壁70を有する横連結部材62の主胴

例えば補強用の突条を横連結部材62の上面に設ける必要
がなく、リヤフォーク36の軽量化（ばね下荷重の低減
化）を企画し得るとともに、空気清浄器92の容量を大き
く確保する上でも有利である。The top wall 72 and the back wall 74 are L-shaped in cross section, and the main body portion 68 of the lateral connecting member 62 having the partition wall 70 inside is hollow and has large bending rigidity and torsional rigidity.
For example, it is not necessary to provide a ridge for reinforcement on the upper surface of the lateral connecting member 62, and it is possible to plan the weight reduction of the rear fork 36 (reduction of unsprung load) and to secure a large capacity of the air purifier 92. But it is advantageous.
主胴部68がＣ点（第３図）を上方ないし後方から覆う
Ｌ字形断面形状になされているため、Ｃ点が腕38，50の
側壁40，52で挟まれる空間部位にあってもリンク30の揺
動が保証される。換言すれば、斯かる形状の主胴部68は
側壁40，52で挟まれる空間部位にＣ点を置くことを可能
にする。Since the main body portion 68 has an L-shaped cross section that covers the point C (Fig. 3) from above or from the rear, even if the point C is in a space portion sandwiched between the side walls 40 and 52 of the arms 38 and 50, a link is formed. 30 swings are guaranteed. In other words, the main body portion 68 having such a shape enables the point C to be placed in the space portion sandwiched by the side walls 40 and 52.

用せず、横連結部材62と腕38，50との溶接部に対するボ
ルト締め付け力の影響がない。Bolt 8 for connecting the link 30 to the rear fork 36
8. Since the tightening force of the nut 90 acts on the lateral connecting member 62, the tightening force does not act on the arms 38 and 50, and the bolts are tightened to the welded portion between the lateral connecting member 62 and the arms 38 and 50. There is no influence of power.
ボルト88，90の締め付けは、腕38，50とは無関係にこ
れを行なっているため、ボルト88の長さが短く、リヤフ
ォーク36の軽量化、ばね下荷重の低減化に寄与し得る。Since the bolts 88 and 90 are tightened regardless of the arms 38 and 50, the length of the bolt 88 is short, which can contribute to weight reduction of the rear fork 36 and reduction of unsprung load.
