ラントフレーム構造。[Claims for Utility Model Registration] A power plant frame is provided with a transmission case, a rear differential, and a drive shaft that connects the two, and is arranged so as to surround the drive shaft. In the structure of the power plant frame that connects the power plant frame with the steering wheel, the power plant frame has a substantially U-shaped cross section, and a damping material is attached to the outer surface of the power plant frame. A power plant frame structure characterized in that a lower portion of the power plant frame is coated with a cover material so as to cover the vibration damping material.
