【発明の詳細な説明】
（産業上の利用分野）
本発明は、排気ガスを浄化するための触媒コンバータに
関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a catalytic converter for purifying exhaust gas.
（従来の技術）
車輌用の触媒コンバータにおける担体として、芯棒に波
状金属板を多重に巻付けたものが多く用いら江ている（
例えば特開昭５５−１４５５３７号公報参照）。(Prior Art) As a carrier in a catalytic converter for a vehicle, a material in which corrugated metal plates are wrapped multiple times around a core rod is often used (
For example, see Japanese Patent Application Laid-open No. 145537/1983).
（発明が解決しようとする問題点）
上記メタル担体は、構ＩＡ簡単にして製作が容易である

氷見ＢＡは、かかる問題点を踏決するためになさ１″し
たもので、Ｓ／■比の商い加速時にも高い浄化性能が得
らルる触媒コンパ〜りを得ることを目的とする。(Problems to be Solved by the Invention) The above metal carrier has a simple structure and is easy to manufacture, but it has a problem in purification performance during acceleration with a high S/V ratio (combustion chamber surface area/volume ratio). The Chiri to Himi BA was created in order to solve this problem, and its purpose is to obtain a catalyst compounder that can obtain high purification performance even when the S/■ ratio is accelerated.
（問題点を解決するための手段）
本発明は、メタル担体の中央部における巻き数を密にす
るため、中央部における波状金属板の波高と基板の板厚
とを最小にする、というものである。(Means for Solving the Problems) The present invention minimizes the wave height of the corrugated metal plate and the thickness of the substrate in the central part in order to make the number of windings dense in the central part of the metal carrier. be.

スに対する汲触面槓と外周部よシも大きくとルることに
ａ Ｄ 、ｓ／ｖ比の高い加速時でも高い浄化性能が得
らｎることになる。(Function) Since the number of windings in the central part of the metal carrier is dense, the contact surface against the exhaust gas and the outer peripheral part are also large during acceleration with high aD and s/v ratios. However, high purification performance cannot be obtained.
（実用例）
以下、本発明の実施例を、図面を参照しながら説明する
と、第１因において、１は基板であって、その板厚は、
一端部Ａが最小で他端部Ｂが最大となっており、つまシ

増加する形状となっている。(Practical Example) Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the first factor, 1 is a substrate, the thickness of which is:
One end A is the minimum and the other end B is the maximum, and the plate thickness of the holder and the board 1 increases by M order from the -shoulder A to the other end.
該基板１の１つの而には、波形状の金属板２が添設さ几
ている。該波形状全橋板２の波高りは、一端部が最小で
１ｍ４部が最大となっている。A corrugated metal plate 2 is attached to one of the substrates 1. The wave height of the corrugated full bridge board 2 is minimum at one end and maximum at 1 m4.

い。なお、同図では、波状金属板２の中間の区間は省略
さｎている。As shown in the figure, the direction of increase in wave height from one end A to 1111 end B is determined stepwise by dividing the corrugated metal bridge board 2 into a plurality of sections 5L-, , and d, which are the same. The wave height within a section may be the same and the wave height may be different in adjacent sections, or the wave height may be made to increase continuously from one end to the other end B. good. In addition, in the figure, the middle section of the corrugated metal plate 2 is omitted.

側になるように一端側から巻いてメタル担体３を形成す
る。In this way, if the corrugated metal plate 2 is attached to the substrate 1 with one end A of the substrate 1 and the metal plate 2 corresponding to the other end B, the corrugated metal plate 2 is attached to the substrate 1, as shown in FIG. The metal carrier 3 is formed by winding it from one end so that 2 is on the inside.

うに設定さｎているので、メタル担体３は、中央部はど
巻き数が密になっている。換ぎすｎば、メタル担体３の
径方向における基板１の間隔は、中央部はど小さく、外
周部はど大になる。Since the thickness of the substrate 1 and the wave height of the corrugated metal plate 2 are set as described above, the metal carrier 3 has a dense number of turns at the center. If this is done, the spacing between the substrates 1 in the radial direction of the metal carrier 3 will be smaller at the center and larger at the outer periphery.

ても高い浄化性能が得られることになる。(Effects of the Invention) As is clear from the above, the distance between the substrates in the radial direction of the metal carrier is smaller at the center and larger at the outer periphery, so that contact with the catalyst is prevented with respect to the flow of exhaust gas. In other words, 't'' LV! The same effect as increasing the contact time of exhaust gas with the catalyst can not be obtained, so even during acceleration with a high SZv ratio, the area is large. Purification performance will be obtained.

的構成になり、変形や感動を吸収できることになる。In addition, by configuring the metal carrier as described above, the rigidity at the center part of the metal carrier is high and the rigidity at the outer peripheral part is low, so that high gas pressure acts on the metal carrier when the S/V ratio is high. The metal carrier is a rigid, soft structure because the metal carrier can be slightly deformed at its outer periphery and can return to its original shape when vibrations from the engine are applied. It becomes an equivalent structure, and can absorb transformation and emotion.
