摘要： [Problems] In a rocker arm-type valve mechanism of 4-stroke internal combustion engine, a sliding roller-type rocker arm for reducing friction is provided.
[Solutions] In a rocker arm-type valve mechanism of 4-stroke internal combustion engine, a rocker arm that is one component of the mechanism comprises 4 components in total, including a body110, a roller shaft 120, and two rollers of an inner ring roller 130 supported by the roller shaft 120 and an outer ring roller 140. In sliding-type rocker arm, the inner ring roller is made of resin material to reduce the friction due to sliding. Furthermore reinforced fibers are arranged in parallel to the sliding direction of the inner ring roller to reduce the friction.
