A power transmission device for a vehicle, comprising:

• a housing that accommodates a power transmission mechanism;
• a partition section that supports the power transmission mechanism and divides an interior of the housing;
• a strainer arranged at a bottom of the housing;
• and
• a pump assembled onto the partition section, wherein
• the housing defines
• a first chamber located on one side of the partition section in a direction of an axis of rotation of an input shaft of the power transmission device, and
• a second chamber located on the other side of the partition section in the direction of the axis of rotation of the input shaft of the power transmission device, and
• the strainer has
• a first connection port that connects to the pump, and
• a second connection port that connects to an oil path inside the partition section, the second connection port being connected to the oil path from a direction of assembly of the pump onto the partition section so that the second connection port is connected to the oil path on a side of the partition section that is the same as the side of the partition section to which the pump is assembled onto.
