ができた。 By partially reinforcing the structure of the conventional rocker arm, the inventors have created a rocker arm made of synthetic resin material, which weighs less than 30% of the conventional rocker arm made of metal material. Moreover, we were able to obtain a Rotsuker arm that is comparable in strength. In other words, the first place to break in the Rocker arm is the tensile stress generating part of the valve side arm, and after confirming that the tensile stress generating part is on the same side as the sliding surface of the cam side arm, Attach a reinforcing cloth made of woven or non-woven fabric made of glass fiber etc. from the sliding surface of the arm to the tensile stress generating part of the valve side arm, or attach a reinforcing cloth made of glass fiber etc. In addition to increasing the moment, the rigidity of the valve side arm is increased by attaching a reinforcing cloth made of woven or nonwoven fabric made of glass fiber to the sliding surface side of the cam side arm. By increasing the abrasion resistance of the sliding surface of the arm, it is possible to obtain a lightweight Rocker arm made of synthetic resin material that has the same strength as one made of metal material.
