PURPOSE:To reduce roll displacement quantity at the accelerating and turning time of a vehicle by controlling the actuator member of an engine mount device into the roll reducing direction at the roll displacement generated time of an engine. CONSTITUTION:Control circuits 16A, 16B receive the extensional deformation detection signals of an expanding side engine mount device 1A or 1B at the roll generated time from other party side displacement sensors 15B, 15A, amplify the levels of the input signals at signal amplifying parts 51 and then detect the DC voltage levels at DC level detecting parts 52. Current control signals corresponding to the DC voltage levels indicating the extensional displacement quantity are further formed at voltage-current converting parts 53, and the current control signals corresponding to the expanding side displacement quantity are applied to other contraction side self-coil parts 14B, 14A so as to drive a super-magnetostrictive member 12 inversely in the expanding direction. The contraction quantity of the contraction side engine mount devices 1A, 1B at the roll displacement time can be thereby made small. |
