A power transmission device for a vehicle includes a housing that accommodates a power transmission mechanism, a control valve configured to control an oil pressure supplied to the power transmission mechanism, a first pump and a second pump configured to supply oil to the control valve. The housing includes a first chamber that accommodates the power transmission mechanism and the first pump, and a second chamber that is arranged adjacent to the first chamber in a horizontal line direction. In the first chamber, the first pump is arranged such that an axis of rotation of the first pump extends along a direction of an axis of rotation of the power transmission mechanism. In the second chamber, the control valve is arranged upright. In the second chamber, the second pump is arranged upright with an axis of rotation of the second pump extending along a vertical direction.
