らない。However, in the mold 2 for the slip casting of the slurry, when the casting is repeated, the filtration layers 7 and 8 gradually become thin or chipped, so that the cylindrical portion S-1 is not formed. A slight gap is formed without the mold-matching surface portion A being formed being in close contact. Therefore, as shown in FIG. 4, in the obtained molded body 1, burrs 1 c are formed on the inner peripheral surface side edge of the cylindrical portion 1 b.
The burrs 1c must be removed because they hinder the attachment of a muffler, drainage fitting, etc. (not shown) to be performed later.
