A pendulum type mount system includes a pair of upper mounts that mount upper portions of a powerplant unit on a vehicle body, and a pair of first and second lower torque rods. The first and second lower torque rods are located on opposite sides to each other with respect to a reference plane including a gravity center of the powerplant unit. A first spring constant of the first lower torque rod is not smaller than a second spring constant of the second lower torque rod. A distance between a first plane including the first lower torque rod and the reference plane is not larger than a distance between a second plane including the second lower torque rod and the reference plane.
