PROBLEM TO BE SOLVED: To realize a structure which can reliably push grease into a recess of an irregular part of a member to be coated, and can prevent the member to be coated, a coating device or the like from being contaminated by excessive grease.SOLUTION: A salient part 16 is formed at a front side portion of a worm wheel 2 in a rotational direction rather than a discharge port out of a tip face of a body part 13, and a grease pressing face part 17 for pushing grease 1 into a recess of a worm wheel tooth 3 while scraping and smoothening the grease so that the grease becomes substantially equal with respect to a width direction and a circumferential direction of the worm wheel tooth 3 is arranged at a tip face of the salient part 16. Furthermore, a protrusive wall 18 for preventing the movement of the grease 1 to a rear side with respect to the rotational direction of the worm wheel 2 is arranged at a rear side portion of the worm wheel 2 in the rotational direction rather than the discharge port out of the tip face of the body part 13.SELECTED DRAWING: Figure 3 |
