PROBLEM TO BE SOLVED: To prevent cavitation. SOLUTION: A liquid-sealed type vibration control device comprises an outer cylinder, an inner cylinder, an elastic body for elastically connecting the outer cylinder and inner cylinder, a partition member 15 for demarcating a liquid chamber in the outer cylinder into a main liquid chamber and sub-liquid chamber, and a limiting passage 41 for communicating the main liquid chamber with a sub-liquid chamber, wherein a main chamber side opening 42 is formed at one end in a flow path length direction of the limiting passage 41, a sub-liquid chamber side opening 43 is formed at the other end in the flow path length direction of the limiting passage 41, and a swelled part 46 swelled to an inward side of the limiting passage 41 is formed in at least one of the wall part 45 of the limiting passage 41 adjacent to the other end in the flow path length direction of the main chamber side opening 42 and the wall part of the limiting passage 41 adjacent to one end in the flow path length direction of the sub-liquid chamber side opening 43.
