At this time, for example, if the material of the inner members 13 and 17 is a rolled steel plate and the material of the outer members 14 and 18 is an aluminum plated steel plate or a stainless steel plate, the coating after welding can be omitted. That is, when the outer members 14 and 18 are made of a heat-resistant and corrosion-resistant material such as an aluminum-plated steel plate or a stainless steel plate, the welded portion is protected by a passivating anti-corrosion effect. ,
An extra step of additionally winding a stainless steel plate on the surface can be eliminated.

Further, the inner and outer members are formed of different materials as in claim 4, and the inner and outer members are formed with different thicknesses as described in claim 5, and the inner and outer members are formed to have different thicknesses. Or 1
If the built-in member is held in the outer cylinder member by the method of assembling the exhaust muffler described in the section, for example, weight reduction becomes easy, and it is possible to easily respond to the demands of the variety of appearance design and to reduce the cost. Is also possible. Claim 6
The outer material is made of a heat-resistant and corrosion-resistant material such as a stainless steel plate or an aluminum-plated steel plate, and the inner material is made of a rolled steel plate. The exhaust muffler according to any one of claims 1 to 5, By holding the built-in member on the outer cylinder member by the mounting method, post-processing such as corrosion-resistant coating after welding can be eliminated, and if the inner material is a rolled steel plate, the necessary strength can be secured while reducing costs. Can be achieved. Further, a locking means for locking the inner plate and the outer plate at the time of forming the outer cylinder member and / or the end plate is formed as in claim 7, wherein the locking means is formed. If the built-in member is held on the outer cylinder member by the method for assembling the exhaust silencer described in (1), the inner and outer members are less likely to be separated, handling during assembly becomes easier, and productivity can be improved.
