Abstract
In a self-lubricating transmission device 1, a compression helical spring 15 is provided to urge an impregnation metal 14 as an impregnation means so as to slidably contact the impregnation metal 14 with pin rollers 7. In combination with a rotational movement of a pinion 6, the pin rollers 7 slide on a lower surface 14d of the impregnation metal 14 to supply a lubrication oil W to the pin rollers 7 so as to automatically lubricate the pinion 6 evenly at the right time for an appropriate amount of the lubrication oil W. This obviates the lubrication oil W being wastefully used, while at the same time, making a lubrication work quick, labor-saving and user-friendly.
