Abstract
A transmission of a wheel loader is configured so that a rotation speed ratio of an output shaft with respect to an input shaft is changed by changing the rotation speeds of a first motor and a second motor. A transmission case has an input shaft case for containing the input shaft. A lower part of the input shaft case includes a curved surface part. The curved surface part is curved to protrude downwards. The first motor and the second motor are arranged below the input shaft. At least a portion of each of the first motor and the second motor overlaps the curved surface part in a projection view in the up-down direction.
