Abstract
A rocker arm supported by a support portion of an engine and to be driven by a cam includes a sheet-metal rocker arm body manufactured by plastic working and including a cam follower, a fulcrum portion manufactured by cutting and including a through hole supplying lubricant, and a lubricant discharging hole. The cam follower includes a first slide-contact surface being in sliding contact with the cam. The lubricant discharging hole is defined by an outer surface of the fulcrum portion and an outer surface of the sheet-metal rocker arm body and in communication with the through hole. The lubricant discharging hole biases the lubricant supplied from the through hole in a direction toward the first slide-contact surface.
