A vibration isolation apparatus comprises an outer cylinder connected to one of a vibration producing portion and a vibration receiving portion, an inner cylinder connected to the other of the vibration producing portion and the vibration receiving portion, and an elastic member which is disposed between the outer cylinder and the inner cylinder and which deforms when vibration is generated. The vibration isolation apparatus further comprises a unit having both a plurality of restricted paths and a rotary apparatus able to open and close at least one of the restricted paths. Thus, the restricted paths and the rotary apparatus are housed in a unit. As a result, assembly of the vibration isolation apparatus can be improved.
