PROBLEM TO BE SOLVED: To improve a driving comfortability over an entire riding comfortability frequency in a mount device for a vehicular power plant. SOLUTION: A power plant P is supported at a vehicle body frame F through an engine side main mount 6 and a transmission side main mount 7 installed on a substantial inertia main shaft of the power plant P. A pair of upper and lower torque rods 38, 45 are arranged between the power plant P and the vehicle body frame F above and below the driving shafts 48L, 48R extended from a transmission T. Upper and lower fixed values in a mount system including both main mounts 6, 7 and both torque rods 38, 45 are set to 5 to 7 Hz and at the same time a rolling fixed value around the inertia main shaft in the mount system is set to 7 to 10 Hz, respectively, and an attenuation peak frequency of both main mounts 6, 7 is set to 9 to 15 Hz.
