Abstract
An active type of mounting device for mounting a power unit to a vehicle body includes a vibratory member which generates vibrations so as to damp external vibrations applied to the mounting device from the power unit. The resonance frequency of the vibratory member is regulated by varying of the supporting stiffness or flexibility of the vibratory member or by varying of a variable mass attached to the vibratory member to obtain a specific frequency within a frequency band of external vibrations according to engine speed and/or vehicle speed.
