ABSTRACT:
A rocker arm made from a carbon-fiber reinforced resin is disclosed wherein various axes are defined with particularity such as the central axis of the hole through which the rocker shaft is inserted (Z-axis), a line parallel to the edge of the valve side (Y-axis) and the line that is parallel to the cam side (Y'axis). The bisect of the angle at which the Y-axis crosses the Y'axis is the X-axis. Further, cos.sup.2 .beta. of the carbon fibers present in the Y- or Y'axis side with respect to the X-Z axis is defined in detail where .beta. is a defined angle of orientation as is cos.sup.2 .alpha. which is defined in the specification.
The rocker arm is produced by filling a rocker arm mold with a carbon fiber-containing synthetic resin such that cos.sup.2 .beta. of the carbon fibers meets a defined value to such an extent that the cos.sup.2 .alpha. meets a defind value. The rocker arm is lighter and stronger than conventional rocker arms.
