Abstract

A coupling lubrication structure includes a driving shaft (1) of an internal combustion engine; a coupling (2) that connects an end portion of the driving shaft (l)to a driven shaft (31) of a driven element; (3) and a first oil passage (65) and a second oil passage that are formed in the driving shaft, (1) and that extend in the direction, in which the axis of the driving shaft extends, toward the downstream side on which the coupling (2) is provided. A branch passage leading to an engine component that needs lubrication branches off from the first oil passage. The second oil passage leads to the sliding portion of the coupling.
