Pipe 28, and it is connected to the through hole 27A of ceramic wafer 27 with ceramic tube 28.In this case, the inside of ceramic tube 28 becomes the 1st stream
Road, the gap between ceramic tube 28 become the 2nd flow path.
The holder being configured on the peripheral wall of honeycomb structure is not limited to cover the entire circumferential mode of peripheral wall
Be formed as cricoid structure.As long as the opening for not covering the 1st interconnecting part 24a being formed on the peripheral wall of ceramic body is connected to the 2nd
The opening of portion 24b then can change size in the axial direction and circumferential direction of ceramic body.Also, it can also arbitrarily change holder
Thickness setting.For example, can also be set as identical as the height of the height of the 1st rib and the 2nd rib, or can be set as comparing
The height of two ribs is thick.
The shape of honeycomb structure is not limited to cylindric.For example, prism-shaped can also be formed as.It can also cooperate
The shape of such ceramic body changes and changes the shape of shell.
Using the weld part of housing body as boundary, shell is constituted by 2 components, but constitutes the number of the component of shell
Amount is not limited to 2.It is also possible to 3 or more.Also, it is divided into the position of multiple components to be not limited to shell shell
The central portion of main body.For example, it is also possible to which shell is cut in the position punishment for being configured to the boundary in housing body Yu the 1st perforated wall.
The structure in the 1st axially open portion is not particularly limited.Connect for example, can replace including the 1st perforated wall and the 1st
The structure of adapter tube, but be configured to be arranged in the end of housing body further away from the end cone wall that then diameter more becomes smaller.Also,
1st connecting tube can also be configured to further away from the 1st perforated wall cone cell that then diameter more becomes smaller.In addition, the 2nd axially open portion
Structure is similarly not particularly limited.
1st radial opening portion and the 2nd radial opening portion have no special limit relative to the position of the circumferential surface of housing body
It is fixed.For example, it is also possible to the 2nd radial opening portion be configured the configuration of the 1st radial opening portion in the 1st axis in the 2nd axially open portion side
To opening portion side.Also, in the horizontal direction across the central axis of housing body when can also be with from the end on observation of shell
Mode configure the 1st radial opening portion and the 2nd radial opening portion.That is, the 1st radial opening portion and the can also maintained
2 radial opening portions make them in the state of in the radial direction (direction vertical with the axis direction of shell) of shell opposite to each other
90 degree of displacements are carried out around the axis of shell.
The cross sectional shape of seal member is not particularly limited.For example, C-shaped section can be used as shown in Figure 9.At this
In the case of, there is the 1st annulus 31 and the 2nd annulus 32 of a pair of of the free end configuration open as peripheral side, and have and connect
Connect the interconnecting piece 33 of the inner peripheral side end portion of two the 1st annulus 31 and the 2nd annulus 32.As shown in Fig. 9 (a), the 1st annulus
