Abstract
A rocker arm includes a roller brought into contact with a cam to be rotated and an arm body having a storage portion for the roller. The storage portion has an opening edge including a part receiving lubricant oil flowing along an upper surface of the arm body. The part is formed with a receiving opening edge jutting out so that both widthwise ends are located away from a circumferential surface of the roller and so that a widthwise central portion comes closer to the circumferential surface of the roller. The arm body has a lubricant guide path formed by recessing the upper surface thereof and guiding the lubricant oil into the storage portion. The lubricant guide path has a width that is gradually rendered larger as the lubricant guide path gets close to the widthwise central portion of the receiving opening edge.
