PROBLEM TO BE SOLVED: To provide a power unit mount structure for a vehicle, suitable for forward-backward suppression of low-frequency wave generated at the vehicle. SOLUTION: As a power unit 1, an engine 2 and a transmission 3 are transversely mounted in a vehicular front portion, elastically supported on a vehicle body 7 by a pair of mounts 5, 6 disposed in vehicle forward-backward positions and are configured such that a front wheel 20 is driven by the torque generated by the power unit 1. The mount 5 on the vehicle forward side is provided with a direction change mechanism (16) which applies an energizing force for switching to a vehicle advance direction to the power unit 1 when the power unit 1 rolls around a crankshaft 4 to be switched relatively to the upper direction. On the other hand, the mount 6 on the vehicle backward side is provided with the direction change mechanism (16) which applies an energizing force for switching to a vehicle advance direction to the power unit 1 when the power unit 1 rolls around the crankshaft 4 to be switched relatively to the lower direction.
