ある。Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to exhaust gas purification catalysts and particulate purification filters for internal combustion engines, as well as purification and/or deodorization catalysts for combustion gases fueled by various gases and petroleum. The present invention relates to a method for manufacturing a ceramic honeycomb structure used as a carrier.

る。(Prior Art) In order to withstand severe vibrations during use, conventional automotive catalytic converters that have been put into practical use are installed in a direction perpendicular to the through hole 21-1 through which exhaust gas passes (as shown in FIG.
In the “radial direction J” below, there is a cushion material 22-1,
Applying pressure via 22-2 and sealing material 22-3,
Further, in the direction of the through hole, a structure is adopted in which the plate material 23 is fixed and held while applying pressure through a cushion material 22-1.

る。However, in the case of the above structure, the exhaust gas cannot pass through the ceramic honeycomb structure through-hole 21-2 in the portion of the cushion material 22-1 that is in contact with the through-hole direction, and the exhaust gas purification function is not fulfilled. Catalyst is wasted. Therefore, as shown in Fig. 7, a method of using only sealing material on all sides and holding it only in the radial direction has been put into practical use in order to save catalyst precious metals.
As disclosed in Publication No. 0, one or more locking portions are provided on the outer periphery of the ceramic honeycomb structure to prevent rotation or displacement due to vibrations when a catalytic converter is constructed with a cushion material. Things are also known.

適用できない問題がある。(Problem to be solved by the invention) However, with the method of holding only in the radial direction, which has been put into practical use in some places, it is necessary to apply high pressure in the radial direction in order to withstand severe vibrations during use. If the thickness of the partition walls of the honeycomb structure is relatively thick, such as 0.3 mm, and the external pressure strength is high, it is possible to hold the honeycomb structure only in the radial direction, but if the thickness of the partition walls is, for example, 0.15+n
If it is relatively thin like l11, the external pressure strength is low (
There are some problems that cannot be applied.

有効に防止することができる。(Function) In the above configuration, a part of the mask can be moved in and out of the ceramic honeycomb structure during extrusion of the ceramic honeycomb structure of a predetermined composition, or by applying a mold or cutting it with a thin line immediately after extrusion. Accordingly, a recess can be provided in a part of the outer surface. Therefore, when the obtained ceramic honeycomb structure is incorporated as a converter together with a sealing material, the contact force between the sealing material and the surface recess becomes strong, causing a shift in the direction of the through-hole of the ceramic honeycomb structure and a centering around the direction of the through-hole. This can effectively prevent rotation.
