To suppress a cost.SOLUTION: A vibration isolator comprises: a cylindrical outside attachment member 11 connected to either of a vibration generation part and a vibration receiving part; an inside attachment member 12 connected to the other, and arranged inside the outside attachment member; and a pair of main body rubber 13 for connecting the outside attachment member and the inside attachment member. Accommodation recesses 14 are formed at portions located between a pair of the main body rubber, and located at both sides of the outside attachment member with a center axial line O sandwiched in a radial direction between the outside attachment member and the inside attachment member, deformable accommodation bodies 21 in which liquid chambers are formed at the inside are fit into the accommodation recesses, the accommodation bodies are connected via an orifice pipe 22 for making the liquid chambers communicate with each other, and the accommodation bodies and the orifice pipe are integrally formed by a resin material.SELECTED DRAWING: Figure 1
【課題】コストを抑える。【解決手段】振動発生部および振動受部のうちのいずれか一方に連結される筒状の外側取付部材11、および他方に連結されるとともに外側取付部材の内側に配設された内側取付部材12と、外側取付部材と内側取付部材とを連結する一対の本体ゴム13と、を備え、外側取付部材と内側取付部材との間において、一対の本体ゴム同士の間に位置し、かつ外側取付部材の中心軸線Oを径方向に挟む両側に位置する各部分に、収容凹部14が配設され、各収容凹部に、内側に液室が形成された変形可能な収容体21が嵌め込まれ、各収容体は、それぞれの液室同士を連通するオリフィス管22を介して連結され、各収容体およびオリフィス管は、樹脂材料で一体に形成されている。【選択図】図1
