産業上の利用分野
この考案は、いわゆるCVT（Continuously
Variable Transmission）用の摩擦伝動チエーン
に関する。[Detailed explanation of the invention] Industrial application field This invention is a so-called CVT (Continuously
Regarding friction transmission chains for variable transmissions.
従来技術及びその問題点

端面とリンクプレート２Ａ，２Ｂが面一になつて
いるので組立てた後はブシユ３の隙間より潤滑油
が侵入しにくいという問題がある。PRIOR ART AND PROBLEMS THEREOF FIG. 4 shows a conventional friction transmission chain in which a pair of approximately U-shaped strut pieces 1 and 1' are arranged in an endless manner. A link plate 2 is press-fitted into a bushing 3 and connected with a connecting pin 4. 5 is a joining pin for integrating both strut pieces 1, 1'.
In this case, the link plates 2A and 2B are press-fitted from both sides of one bushing 3 (it is difficult to press-fit bushings into one link plate accurately, so two plates are often press-fitted one on top of the other), but the bushing 3 Since the end faces of the bushings 2A and 2B are flush with each other, there is a problem that lubricating oil is difficult to penetrate through the gaps between the bushings 3 after assembly.
問題点を解決するための手段及び作用
本考案は、圧入されたブシユがリンクプレート
の側面から突出する部分を有するようにすること
により上記問題点を解決した。Means and Effects for Solving the Problems The present invention solves the above problems by providing the press-fit bushing with a portion that protrudes from the side surface of the link plate.
組立て後には、隣りのブシユに圧入されたリン
クプレート同士の間に隙間ができるので、この部
分から潤滑油をブシユ間の隙間を経てブシユと連
結ピンの間に導くことができる。 After assembly, a gap is created between the link plates press-fitted into adjacent bushes, so lubricating oil can be introduced from this gap through the gap between the bushes and between the bushes and the connecting pin.
実施例

エーン部分の構成は第４図のものと同様である。Embodiment As shown in FIGS. 1 and 3, when the link plates 2A and 2B are press-fitted into the bushing 3, the bushing 3 has a portion that protrudes from the side surface of the link plates 2A and 2B. The structure of other chain parts is the same as that in FIG. 4.
さらにストラツト片の断面形状を第２図に示す
ように変更して走行中のチエーンに対して潤滑油
を充分吹き付けられるようにすることもできる。 Furthermore, the cross-sectional shape of the strut piece can be changed as shown in FIG. 2 so that a sufficient amount of lubricating oil can be sprayed onto the running chain.
第２図に実線で示したものは、直角ノズル６で
潤滑油を供給する場合で、ストラツト片１，１′
の上下部分の断面形状は略台形としている。 The solid line in Fig. 2 shows the case where lubricating oil is supplied by the right-angled nozzle 6, and the strut pieces 1, 1'
The cross-sectional shape of the upper and lower parts is approximately trapezoidal.
想像線で示したものは傾斜ノズル６′で給油す
る場合で、前記断面形状は略平行四辺形としてい
る。 The imaginary line shows the case where oil is supplied by an inclined nozzle 6', and the cross-sectional shape is approximately a parallelogram.
考案の効果
