At positions corresponding to the elastic retaining rings 7, 7, there are strip-like locking bodies 8, 8, each having an arc shape.
...is fixed by welding. All of these have the same structure, and a developed view of one of them is shown in FIGS. 3 to 5. A large number of semi-conical claws 9, 9, . . . are cut and raised on the entire surface of the band plate-like locking body 8 at appropriate intervals by extrusion, and the tip 10 thereof has a sharp corner. 1
Reference numerals 1 and 11 denote welding points, which are fixed to the inner surfaces of the upper half 2 and lower half 3 of the housing 1, respectively, by spot welding. The directions are opposite to each other. for example,
The tips 10, 10 are welded facing each other. The shape of the claw 9 can also be pyramidal, as shown in FIG. 6 and 12.

られているから、係止力は極めて大きい。 With the above structure, when the catalyst carrier 6 is inserted between the upper half 2 and the lower half 3 of the housing 1 and the upper and lower rough flanges 4 and 5 are fixed together, the elasticity of the outer periphery of the catalyst carrier 6 The claw 9 bites into the retaining ring 7 from the tip 10 and locks it, especially at the arrow A in FIG.
The movement of the catalyst carrier 6 in this direction is prevented. Since the left and right claws 9, 9 are oriented in opposite directions, movement of the catalyst carrier 6 in the longitudinal direction is completely prevented, and since a large number of claws 9 are provided, the locking force is extremely large.

実である。(Effects of the invention) The present invention does not use pins, screws, etc. that require drilling into the housing as in the prior art, so they may become unlatched or lose airtightness due to loosening or falling off. Since the strip plate-like locking body 8 is welded to the upper and lower halves of the housing 1, the structure is extremely simple and robust. Since the catalyst carrier can be locked by simply fixing them together, it is easy to handle.Moreover, the strip-shaped locking body 8 is provided with a large number of claws 9, each of which is attached to the elastic retaining ring 7. The total locking force is extremely large, and the locking action is reliable.
