ABSTRACT:
A vibration absorbing apparatus disposed between a vibration source and a vibration receiving portion and having a tubular member which is formed such as to pass through an expandable liquid chamber and which is attached to one of the vibration source and the vibration receiving portion. A partitioning plate is secured to the outer periphery of the tubular member such as to divide the liquid chamber into a plurality of liquid sub-chambers. The liquid sub-chambers communicate with each other via an orifice. Accordingly, even if the direction in which vibration acts upon the apparatus is shifted, it is possible to prevent the occurrence of "pinch" between the partitioning plate and the tubular member.
