<p>A rocker arm (100,100a,100b,100c) configured to be supported by a support portion (210) of an internal-combustion engine (220) and to be driven in a swinging manner by a cam (410). The rocker arm includes a rocker arm body (110a) including a cam follower (140) having a first slide-contact surface, wherein the first slide-contact surface is in sliding contact with the cam (410), a fulcrum portion (120a) including a second slide-contact surface, wherein the second slide-contact surface swingably is in sliding contact with respect to the support portion (210), and a lubricant discharging portion (160) for biasing a lubricant supplied from the fulcrum portion (120a) in a direction toward the first slide-contact surface and discharging the lubricant. The fulcrum portion (120a) penetrates the rocker arm (100,100a,100b,100c) and is fastened to the rocker arm body. The fulcrum portion (120a) has a through hole (120h) supplying the lubricant to the lubricant discharging portion (110j,135h,160h,170) through the rocker arm body (110).</p> |
