とするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chain tensioner or other sliding type chain guide used in a state of being pressed against the chain in a power transmission mechanism using a chain of an internal combustion engine, and constitutes a part of the chain guide. It is an object of the present invention to provide a chain guide having a structure that improves the wear resistance of the elastic member that contacts the chain and prevents the elastic member from peeling off from the plywood.
従来のチェーンガイドに於ける合板表面の弾
性部材（ゴム材）の取付けは、合板に対して無負荷の状
態、即ち台板を直線状態に保ちてその表面に弾性部材を
一体的に取付けていた。In conventional chain guides, the elastic member (rubber material) was attached to the plywood surface in a state where no load was applied to the plywood, that is, the base plate was kept in a straight state, and the elastic member was integrally attached to the surface. .
しかしながら、内燃機関に組み込んでの使用時に於ける
台板形状はチェーンガイド製作時の形状よりも撓ませた
状態で用いるため、弾性部材の表面には常時引張応力が
加わり、それにより台板と弾性部材は剥離したり、弾性
部材の耐摩耗性が悪かった。However, when used in an internal combustion engine, the shape of the baseplate is bent more than when manufacturing the chain guide, so tensile stress is constantly applied to the surface of the elastic member, which causes the tension between the baseplate and the elastic member to deteriorate. The members peeled off, and the wear resistance of the elastic members was poor.

である。This is because: ■ Since the elastic member is used in a flexed state, small scratches on the surface of the elastic member tend to grow and become larger due to the tensile stress; ■ The base plate and the elastic member are moved away from each other This is due to the fact that a force is applied, and (2) the internal structure of the elastic member is always kept in a rough state.

るようにしたものである。However, in the present invention, a band-shaped metal plywood is bent more than the shape when in use, and a band-shaped elastic member is integrally attached to the surface of the plywood in this state, so that the surface of the elastic member is bent when in use. Compressive stress is always applied to the plywood and the elastic member is applied in the direction of adhesion to each other, which improves the wear resistance of the elastic member and prevents the elastic member from peeling off. .

２を一体的に取付ける。Hereinafter, embodiments of the present invention will be described based on the drawings. The chain guide A is composed of a base plate 1 and an elastic member 2 integrally attached to the surface of the base plate 1. The base plate 1 is made of a flat metal plate. The base plate 1 is formed into a band shape with a square cross section, and the base plate 1 is bent more than the shape in use, and the elastic member 2 is integrally attached to the surface of the plywood 1 in this state.
弾性部材２はゴム材２−１（例えばブナ系ニトリルゴ
ム）単体、又は合成樹脂材、或いはゴム材２−１の表面
（即ちチェーンと接触する面）に耐摩耗性に優れた四弗
化エチレン材２−２を一体的に接着した積層構造体を用
いるもそれは任意である。The elastic member 2 is a rubber material 2-1 (for example, beech-based nitrile rubber) alone, a synthetic resin material, or a surface of the rubber material 2-1 (i.e., the surface in contact with the chain) made of tetrafluoroethylene, which has excellent wear resistance. It is optional to use a laminated structure in which the materials 2-2 are integrally bonded.

る。As a means of integrally attaching the elastic member 2 to the base plate 1 as described above, the rubber material 2-1 is molded to fit the curved shape of the base plate 1 which is already bent, and then the elastic member 2 is integrally attached with an adhesive or the like. Either method is possible, such as adhesively bonding the base plate 1 to the base plate 1, or injecting molten rubber into a mold in which the base plate 1 is set in a curved shape, cooling and solidifying the elastic member 2, and attaching the elastic member 2 to the surface of the base plate 1 by vulcanization. be.
図中、３はチェーンである。In the figure, 3 is a chain.
本発明は以上の如く構成したので、弾性部材の表面には
常時圧縮応力が作用すると共に、弾性部材の内部組織は
常に密の状態に保持される。Since the present invention is constructed as described above, compressive stress is always applied to the surface of the elastic member, and the internal structure of the elastic member is always maintained in a dense state.
従って、弾性部材の表面に小さな傷ができたとしてもそ
れ以上大きくならず、亀裂破損といったことを完全に防
止でき、且圧縮応力の作用と内部組織が密であるためチ
ェーンとの接触による摩耗度は小さく、耐摩耗性の向上
を計り得る。Therefore, even if a small scratch occurs on the surface of the elastic member, it will not become any larger, completely preventing cracks and damage, and due to the action of compressive stress and the dense internal structure, the wear caused by contact with the chain will be reduced. is small and can improve wear resistance.
更に、弾性部材と合板とは互いに接着する方向に力が作
用するため、弾性部材が合板より剥離するといった現象
は確実に防止できる。Furthermore, since force acts in the direction of adhering the elastic member and the plywood to each other, it is possible to reliably prevent the elastic member from peeling off from the plywood.
依って、チェーンガイド本来の働きを十分に達し得ると
ころのチェーンガイドを提供でき、所期の目的を達成し
得る。Therefore, it is possible to provide a chain guide that can fully perform the original function of a chain guide, and achieve the intended purpose.
