A transmission for a wheel loader includes first and second oil accumulating parts, a communication oil path, a horizontal hole and a vertical hole. The first oil accumulating part accumulates scattered lubricating oil. The second oil accumulating part is mounted to an end of an output shaft below the first oil accumulating part, and accumulates the lubricating oil from the first oil accumulating part. The communication oil path allows the first and second oil accumulating parts to communicate with each other. The horizontal hole extending axially is formed in the rotary shaft, and communicates with the second oil accumulating part. The vertical hole communicating with the horizontal hole is formed in the output shaft, and directs the lubricating oil accumulated in the second oil accumulating part to the lubricated part when the output shaft is rotated at a rotational speed lower than a predetermined rotational speed. |
