PURPOSE: To manufacture a vibration absorbing pipe by a method wherein two rubber half covers are not stuck together but a clearance is made on an outer periphery of a bellows which is covered with a cylindrical sleeve, a liquid rubber is injected into the clearance by a low pressure, and the liquid rubber is cured.
CONSTITUTION: In manufacturing a vibration absorbing pipe, a bellows 2 made of a thin metal formed into an accordion shape is held vertically. On its outer side, a cylindrical sleeve 6 made of a vulcanized rubber having an internal diameter d larger than an outer diameter D of the accordion part of the bellows 2 is arranged. A liquid rubber 8 is injected into a space 7 to be filled which is formed in between the outer periphery of the bellows 2 and the inner periphery of the sleeve 6 by a pressure below a proof pressure of the bellows 2 and the liquid rubber is cured.
