Claims

[Scope of utility model registration request]

A final reduction gear, in which a reduction gear unit and a differential gear unit are integrated, supplies lubricating oil to the meshing part between the drive pinion gear and ring gear of the reduction gear unit by the rotation of the ring gear, and uses the splashed lubricant oil to drive the gear. In a lubrication mechanism that supplies lubrication and cooling to the bearing portion of a pinion gear, the mechanism protrudes above the meshing portion to prevent excess lubricant from flowing into the meshing portion, and also provides circulation to the rear pinion bearing and front pinion bearing. The lubricating oil is characterized by being provided with a saucer for introducing the lubricating oil into the circulation path, and a stop plate through which lubricating oil is guided and supplied to the front of the front pinion bearing from a supply port formed to protrude from above the front pinion bearing toward the circulation path. Lubrication mechanism for reduction gearing.
