ABSTRACT:
A grease guide structure for a transmission device suitable for a sunroof of an automobile or the like. The transmission device includes a worm wheel and a pinion shaft, which are drivingly connected through a friction clutch mechanism. In order to prevent grease flowing from the worm wheel onto the friction clutch mechanism, a cup washer is mounted between the worm wheel and the friction clutch mechanism, with the center portion of the cup washer being higher than its peripheral portion. Therefore, if grease falls onto the cup washer, it will further flow and finally fall into a grease intake slot which is arranged below the cup washer to be stored therein.
