A fluid filled vibration damping device (10, 112, 210, 312, 322, 464, 540) including: a fluid passage (70, 72) interconnecting a pressure receiving chamber (64) partially defined by a rubber elastic body (16) connecting a first and second mounting members (12, 14), and an equilibrium chamber (66) partially defined by a flexible film (32); a movable valve body (102, 116, 126, 130, 302, 316, 326, 428, 544) provided for switching the fluid passage between a communicating state and a blocked state through reciprocating operation; an electric motor (84, 284, 412) employed for actuating the movable valve body; an actuating force converter mechanism (90, 108, 118, 290, 308, 318, 328, 418, 434) provided on an actuating force transmission path from the electric motor to the movable valve body. A rotational actuating force of the electric motor (84, 284, 412) is transmitted as reciprocating actuating force to the movable valve body (102, 116, 126, 302, 316, 326, 428, 544) by the actuating force converter mechanism (90, 108, 118, 290, 308, 318, 328, 418, 434).
