時にハニカム形状体が外筒より、はみ出すのを防
いだメタル担体を提供することを目的とする。 The conventional method of fixing a honeycomb-shaped body by providing transverse welds at both ends of a metal carrier has a problem in that sufficient welding cannot be achieved because the corrugated plate or flat plate is a thin plate. In addition, in the method of packing a honeycomb-shaped body using a cross-shaped metal fitting and a plate-shaped coil spring, some protrusion occurs from a portion where the cross-shaped metal fitting is not present. Furthermore, if the number of fasteners is increased, the gas passages will be blocked, making it impossible to use the metal carrier for exhaust gas purification. Such deformation of the metal carrier changes the catalyst purification performance, flow path pressure, etc., and prevents safe use of the exhaust gas purification catalyst device. This idea was arrived at after intensive study to prevent the above-mentioned metal carrier protrusion phenomenon from occurring. The object of the present invention is to provide a metal carrier that prevents the honeycomb-shaped body from protruding from the outer cylinder during the above-mentioned use.

It consists of a stopper that is locked to. This stopper prevents the honeycomb-shaped body from deforming due to repeated thermal expansion and contraction during use of the metal carrier, and preventing the deformed portion from becoming longer and protruding outside the outer cylinder. In order to reliably prevent this protrusion phenomenon, a stopper plate that fixes the net parts to each other is provided in the stopper part, and this stopper plate is fixed to the outer cylinder to prevent the honeycomb-shaped body from protruding.

A bolt 12 is inserted into the center of the honeycomb-shaped body 15, and the mesh portion 10 faces both end surfaces of the honeycomb-shaped body 15 (not shown). A stopper plate 11 is placed on the outside of the net portion 10 to press the net portion 10. The stopper plate 11 holds a bolt 12 and has a cylindrical center portion that can be locked with a nut 13, and is formed into an X-shape by welding upper and lower joint portions 14 of the cylinder. This stopper plate 11 is locked with bolts 12 and nuts 13, and each end of the X-shaped stopper plate 11 is welded 9 to the outer cylinder 1 at four locations as in the above embodiment. There is. The metal carrier thus obtained can prevent a portion of the honeycomb-shaped body from protruding outside the outer cylinder 1 during use. Furthermore, if bolts and nuts with a coefficient of thermal expansion smaller than that of the honeycomb-shaped body are used, the pressing effect of the stopper will be improved, resulting in a metal carrier with excellent holding power for the honeycomb-shaped body.
