[PROBLEMS] To efficiently supply a lubricating oil to the lubricating hole of a shaft member. [MEANS FOR SOLVING PROBLEMS] In this lubrication structure of a power transmission apparatus (1) having the shaft member (3) rotatably pivoted on a case (2), a first rotating member (4) carried on the shaft member (3), and a second rotating member (6) engaged with the first rotating member (4), the lubricating hole (5) is formed at the axis part of the shaft member (3) along the axial direction. The power transmission apparatus (1) comprises a lead-in part (9) allowed to communicate with an opening part (8) of the lubricating hole (5), a guide part (12) formed along at least a part of the outer peripheral surface of the second rotating member (6), and a shielding part (13) formed to cover at least a part of the side surface of the second rotating member (6). The lubricating oil scraped up by the second rotating member (6) is guided to near the lead-in part (9) by the guide part (12) and fed to the lubricating hole (5) of the shaft member (3) through the lead-in part (9), and the lubricating oil is prevented from being axially splashed by the shielding part (13). |
