PROBLEM TO BE SOLVED: To provide a liquid sealing type bush capable of ensuring degree of design freedom of balance of elastic characteristic and damping characteristic in, in particular, low frequency region. SOLUTION: This liquid sealing type bush is constituted in such a way that it has an elastic member provided between two members and reducing vibration transmitted from one member to the other member among these two members and non-compression fluid sealed into a space formed in the elastic member, two chambers arranged along the direction of input of vibration in parallel are formed in the space, and these two chambers are mutually communicated by a flow passage in which an orifice is provided on the halfway. A reinforcing member for reinforcing rigidity (horizontal rigidity) in the direction crossing the direction of input of vibration orthogonally when compared with rigidity (vertical rigidity) in the direction of input of vibration of the elastic member is added to the liquid sealing type bush. This reinforcing member is one or more wires arranged along at least a part around the chamber inside the elastic member and having one or more bent parts or curved parts in the vertical direction.
