ABSTRACT:
A hydraulic power transmission device in a work vehicle transmits motive power from two hydraulic motors disposed in parallel to each other. The hydraulic power transmission device includes: a case; a first motor shaft and a second motor shaft respectively disposed in a right-side area and in a left-side area inside the case, each linked to one of the two hydraulic motors; a counter shaft disposed in an area ranging between the first motor shaft and the second motor shaft in the case; an output shaft; a first transmission mechanism that transmits motive power from the first motor shaft to the output shaft via the counter shaft; a second transmission mechanism that transmits motive power from the second motor shaft to the output shaft; and a hydraulic clutch device disposed at the counter shaft, that transmits the motive power from the first motor shaft to the output shaft or cuts off transmission of the motive power.
