PROBLEM TO BE SOLVED: To provide a drive component-lubricating structure designed to prevent drive components or the like from scorching through preventing the drive components' performance drop and grease outflow by eliminating grease temperature and pressure rise. SOLUTION: The drive component-lubricating structure is such that the inside of a gear case 50 is partitioned with a friction plate 60 into a space 55 for housing the basal end side of each of drive components and a space 58 for receiving a grease, a second communicating path 54 is provided to force-feed the grease from the space 55 into the space 58 by the respective pumping effects of a driving gear and a driven gear, and the friction plate 60 is provided with a discharge port 61b for discharging the grease force-fed into the space 58 toward a basal end side housing space 55, wherein the discharge port 61b is provided at a position on the rotary track of the sliding face of the larger turning part of a rod engaged on an eccentric cam provided on the driven gear; and the inside of the gear case 50 is provided with a tip side housing space 57 communicating with the space 55, and the space 55 and the space 57 are made to communicate with each other via a returning communicating path 64.
