Method for manufacturing muffler for vehicle

Provided is a method for manufacturing a muffler for a vehicle, with which it is possible to simply and quickly arrange a sound-absorbing material between an inner cylinder and an outer cylinder of the muffler for the vehicle. A tubular body (6) is molded using a non-woven fabric (2) comprising long-fiber-shaped inorganic fibers (11), and the tubular body (6) is inserted as a sound-absorbing material into a space (S) between an inner tube (72) and an outer tube (71) provided in an inner and outer dual tube constituting a muffler for a vehicle. After one surface (2a) of a non-woven fabric (2) is coated with an adhesive (3), the non-woven fabric (2) is rolled into a tubular shape with the surface (2a) coated with the adhesive (3) as the inner side, the adhesive (3) is made to penetrate into the tubular non-woven fabric (2), and the tubular body (6) is obtained by heating the non-woven fabric (2) to a predetermined temperature. 本发明提供一种能够简单且迅速地进行吸音材料向车辆用消音器的内外二重筒之间的设置的车辆用消音器的制造方法。用由长纤维状的无机纤维(11)构成的无纺布(2)将筒状体(6)成形
