Abstract

A transmission for a wheel loader includes a first oil accumulating part accumulating scattered lubricating oil and a second oil accumulating part accumulating the lubricating oil from the first oil accumulating part. The first oil accumulating part communicates with the second oil accumulating part through a communication oil path. Lubricating oil accumulated in the second oil accumulating part is directed to a lubricated part through a lubrication oil path when a rotary shaft is rotated at a rotational speed less than a predetermined rotational speed. The second oil accumulating part includes a shaft end space disposed at an end of the rotary shaft that accumulates the lubricating oil from the first oil accumulating part. A horizontal hole formed in a center part of the rotary shaft and extending axially allows the shaft end space and the vertical hole to communicate with each other.
