PROBLEM TO BE SOLVED: To provide a power train mount superior in improvement of NVH performance, isolation of low-frequency vibration and vibration insolation effects with respect to transitional vibration and high-frequency vibration. SOLUTION: The power train mount installed between a power train and a structure of a vehicle supporting the power train to isolate vibration propagated between the power train and the structure includes a bracket having a rubber storage part for storing and supporting rubber thereinside; a slant support tool disposed inside the rubber storage part, having a support member connecting part to which a support member installed in the structure or the power train can be connected, and arranged slantly with respect to the horizontal plane of the vehicle; and the rubber bonded with the outer peripheral surface of the slant support tool to surround it, stored in the rubber storage part with the rubber compressed and not bonded with the bracket to elastically support between the slant support tool and the bracket, and having through holes formed around both ends in the slant direction of the slant support tool to reduce dynamic stiffness in the slant direction.
