Claims

[Scope of utility model registration request]

In a gear reduction device that transmits the rotational force of a prime mover of a vehicle to a wheel axle, a hollow hole is provided in a pinion that opens on the shaft end face on the opposite side to the power transmission shaft along the axis of the pinion, and Multiple oil holes are drilled in the pinion shaft bearing seat and the inner ring of the rolling bearing in the radial direction of the pinion shaft, respectively.
and a mechanism for supplying lubricating oil from the outside of the male gear shaft to the hollow hole provided in the pinion gear. A gear reduction device for a vehicle, characterized in that the lubricating oil supplied to the hollow hole is supplied to the rolling bearing transfer surface of the pinion shaft by centrifugal force when the pinion rotates.
