PROBLEM TO BE SOLVED: To make oil easily reach all gear shafts in a gear deceleration mechanism in a lubrication structure for a gear case in which an oil receiving part receiving oil splashed by a gear rotating around a central axial line of a specific gear shaft and an oil supply means for guiding the oil from the oil receiving part to gear shaft sides other than the specific gear shaft are installed in the gear case housing the gear deceleration mechanism and storing the oil.SOLUTION: An intermediate gear shaft 16 is disposed between an input gear shaft 14 and an output gear shaft 15 in side view, and a lower end of an intermediate gear 71 installed in the intermediate gear shaft 16 is disposed at a position lower than lower ends of remaining gears 70, 72, 73 of the gear deceleration mechanism in side view. An oil receiving part 80 is disposed above the input gear shaft 14, the intermediate gear shaft 16 and the output gear shaft 15 and between the input gear shaft 14 and the output gear shaft 15 in side view. |
