This wheel loader (1) is provided with: a mechanical drive unit (21); an HST pump (22) that supplies hydraulic fluid for traveling; an auxiliary hydraulic pump (28) that supplies hydraulic fluid for a bucket (3); a first and second hydraulic motor (23, 24) that are driven by the hydraulic fluid from the HST pump (22); and a motive power combining unit (25) that combines the motive power from the first and second hydraulic motors (23, 24) and the motive power from a mechanical driving unit (21) side. The mechanical driving unit (21) is disposed from the engine shaft to an axial center (C2) output shaft; the motive power from the mechanical driving unit (21) and the motive power from the first and second hydraulic motors (23, 24) are combined above the output shaft at the motive power combining unit (25); and a gear (55) and a first and second combining gear (52, 53) to which the combined motive power is transmitted are disposed between the output shaft and the first and second hydraulic motors (23, 24) positioned vertically. |
