Abstract
A vibration absorption device includes a cylindrical bracket coupled with one of a vibration generating section and a vibration receiving section and having an inner surface formed in a linear shape in a cylinder axial direction, an external cylinder made of resin and including a small diameter section that is formed in a cylindrical shape, press-fit into a cylinder of the bracket, and has a small diameter surface formed to an outer surface configured to a press-fit leading end to the bracket, a large diameter section that has an outer diameter larger than the inner diameter of the bracket and the outer diameter of the small diameter section and a thickness which is configured to a portion nearer to a press-fit rear end side to the bracket than the small diameter section and is thicker than the small diameter section before the press-fit, and a large diameter surface formed to an outer surface, and an intermediate section that is configured between the small diameter section and the large diameter section and has a standing surface formed on an outer surface for coupling the small diameter surface and the large diameter surface, an internal cylinder that is disposed to an inner peripheral side of the external cylinder as well as coupled with the other of the vibration generating section and the vibration receiving section, and an elastic body that is interposed between an inner peripheral surface of the external cylinder and an outer peripheral surface of the internal cylinder for coupling the external cylinder and the internal cylinder to each other.
