Abstract (en)
[origin: EP1630372A1] The shell main body (3) for a muffler includes an inner shell (1) in a cylindrical shape with a cross-section of an imperfect circle defined by small arc portions (4, 5) alternating with large arc portions (6, 7); and an outer shell (2) wrapping the inner shell (1) and formed in a cylindrical shape similar to the inner shell (1). An end portion (1a) of the inner shell (1) and an end portion (2a) of the outer shell (2) are overlapped in a circumstantial direction of the shell main body (3) to form a shell overlap portion (8) that is capable of discharging vapor in a gap (6a, 7a) of the large arc portions (6, 7) formed between the inner shell (1) and the outer shell (2) into one of an outside and an inside of the shell main body (3). This shell overlapping portion (8) is located in one of the small arc portions (4, 5).
