Abstract: A tip end face of a body part 13 is provided at a part in front of a discharge port with respect to a rotational direction of a worm wheel 2 with a protruding part 16, and a tip end face of the protruding part 16 is provided with a grease-pushing surface part 17 configured to push grease into concave portions of a worm wheel teeth 3 while raking and leveling the grease so that the grease is substantially uniform in a width direction and in a circumferential direction of the worm wheel teeth 3. Also, the tip end face of the body part 13 is provided at a rear part of the discharge port with respect to the rotational direction of the worm wheel 2 with a protruding wall part 18 for preventing the grease 1 from moving rearwards with respect to the rotational direction of the worm wheel 2.

Abstract: The present invention relates to a grease application device in which a tip-side inclined surface of a nozzle 28 is made to closely face worm wheel teeth 11 of a shaft-mounted worm wheel 9 while rotating the shaft-mounted worm wheel 9 by means of a drive unit 12. At this state, the grease application device is configured to apply liquid grease from a tip-side opening of the nozzle 28 to the worm wheel teeth 11 of the shaft-mounted worm wheel 9 and to apply the grease while pushing the grease into concave portions of the worm wheel teeth 11. Also, the grease application device is configured to end the application of the grease at a point of time at which the shaft-mounted worm wheel has rotated one revolution with respect to the nozzle 28 after starting the application of the grease to the shaft-mounted worm wheel 9.
