Abstract
In a pivoted tensioner lever extending upward from a pivot axis, both ends of boss through which a pivot shaft extends are provided with funnel-shaped grooves that guide oil adhering to the lever body into a region between the shaft and the inside of the boss. Oil guiding walls, continuous with the boss, and downwardly sloping reinforcing ribs with oil passages formed at their lower ends, increase flow of oil adhering to the lever body to the region between the shaft and the inside of the boss.
