（実施例）
以下、この発明の一実施例を第１．２図に従って詳述す
る。(Example) Hereinafter, an example of the present invention will be described in detail with reference to FIG. 1.2.

側（右側）がエンジンのエキゾーストマニフオールドに
、また出口４側が消音器にそれぞれ連結されている。In FIG. 1, an exhaust pipe 1 as an exhaust route is formed of a metal pipe, with a large-diameter jacket 2 in between, and an inlet 3.
The side (right side) is connected to the exhaust manifold of the engine, and the outlet 4 side is connected to the silencer.

下方向“中央部を境に反対方向に傾斜している。A cylindrical catalyst filter 5 made of foamed ceramic having a honeycomb structure is housed and fixed within the jacket 2. Further, in the jacket 2, a flow velocity control member 6 is provided upstream of the catalyst filter 5 (in the direction of the inlet 3) and extends over almost the entire vertical width of the jacket 2. A plurality of guide plates 8 are vertically inclined in opposite directions with the central portion as a boundary.

手段が構成されている。The above-mentioned driven gear 10 meshes with this rack 12, and as the rank 12 reciprocates, the flow rate control member 6 rotates 1800 times around the rotating shaft 9 via the driven gear 10. The flow rate control member 6 is arranged so that the guide plate 8 widens toward the filter 5 side as shown in FIG. 2 when the exhaust gas E is purified, and when the filter 5 is regenerated
As shown in the figure, the guide plate 8 is switched and held so that it converges toward the center toward the filter 5. Note that the electromagnetic actuator 11, the rack 12, and the driven gear 10 constitute a switching means.
さて、上記のように構成した排ガス浄化装置の作用を以
下に説明する。Now, the operation of the exhaust gas purification device configured as described above will be explained below.

燃焼領域の先端部分の温度が過度に上昇することを阻止
し、フィルター５の中心部に超高温区域が発生すること
な（、同中心部が燃焼されることが防止される。In the state shown in FIG. 1, high-temperature gas G is injected into the exhaust pipe 1 from the inlet 3 side. Then, the high-temperature gas/G is guided by the guide plate 8 of the flow rate control member 6 and enters the filter 5 with the flow rate being faster at the center and slower at the periphery. Therefore, when the harmful component particles of the exhaust gas adhering to the filter 5 are burned by the high temperature gas G, the high temperature gas G passes through the center of the filter 5 at a high flow rate,
This prevents the temperature at the tip of the combustion region from rising excessively, and prevents the generation of an extremely high temperature zone in the center of the filter 5 (and prevents the center from being burned).

The electromagnetic actuator 11 is excited and operated - I, the rack 12
is moved by a predetermined amount, and the gear 10 is rotated 180'. Then, the flow rate control member 6 also rotates by 180'', and the guide plate a becomes wider toward the filter 5 side, as shown in FIG. The exhausted exhaust gas E enters the filter 5 while spreading toward the periphery by the guide plate 8.
Efficient exhaust gas purification is performed by effectively utilizing the entire filter 5, and particles of harmful components contained in the exhaust gas E are collected almost uniformly throughout the filter 5. Therefore, a large amount of particles will not be locally attached to the filter 5, and partial deterioration of the filter 5 can be avoided.

少なくすることが可能となる。As described above, in this embodiment, the flow velocity distribution of the high-temperature gas G entering the filter 5 during regeneration of the filter 5 is made larger toward the center, thereby cooling the ultra-high temperature area generated at the center of the filter 5. Therefore, deterioration and damage to the filter 5 due to heat can be prevented, and furthermore, deterioration of the supported catalyst can be reduced.

The transition between the cleaning operation of the filter 5 and the regeneration operation of the filter 5 can be easily performed.
