る。 In the automobile exhaust pipe shown in the figure, an end 21A of an exhaust pipe 21 is welded and connected to a joint flange 22, and this joint flange 22 can be connected to an exhaust manifold (not shown). The back surface 22A of the joint flange 22 and the outer periphery 21B of the exhaust pipe 21 are supported by a cylindrical reinforcing support 23 to prevent cracks near the joint 21C between the exhaust pipe 21 and the joint flange 22.

However, the joint flange 22, the exhaust pipe 21,
Since the magnitude of each thermal strain of the reinforcing support 23 is different, internal stress is likely to occur in the reinforcing support 23 that connects the joint flange 22 and the exhaust pipe 21.
There was a risk that cracks would occur.

In order to achieve the above object, the present invention provides an automobile exhaust pipe in which the end of the exhaust pipe and the joint flange are welded, and the back surface of the joint flange and the outer periphery of the exhaust pipe are supported by a cylindrical reinforcing support. A slit is formed in the reinforcing support in the axial direction of the exhaust pipe.

The exhaust pipe expands more easily than the reinforcing support due to the heat of the exhaust gas in the exhaust pipe, and the thermal strain that occurs at this time is absorbed by the slit portion, so that no internal stress is generated.
以下、第１図ないし第３図により本考案の実施
例に係る自動車用排気管を詳細に説明する。
DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an automobile exhaust pipe according to an embodiment of the present invention will be explained in detail with reference to FIGS. 1 to 3.

ように、その全長にわたつて一本のスリツト４が
排気パイプ１の軸線に平行に形成されている。 As shown in FIGS. 2 and 3, the end 1A of the exhaust pipe 1 is welded and connected to a joint flange 2, and this joint flange 2 can be connected to an exhaust manifold (not shown) by tightening bolts. It's summery. The back surface 2A of the joint flange 2 and the outer periphery 1B of the exhaust pipe 1 are supported by both ends 3A and 3B of a welded cylindrical reinforcing support 3. As shown in FIG. 1, a slit 4 is formed at the bottom of the reinforcing support 3 over its entire length in parallel to the axis of the exhaust pipe 1.
従つて、排気管１内を流れる排気ガスの熱によ

応力が発生せず、亀裂の発生を防止することがで
きる。 Therefore, the exhaust pipe 1 expands more easily than the reinforcing support 3 due to the heat of the exhaust gas flowing inside the exhaust pipe 1, and the thermal strain generated at this time is absorbed by the slit 4. Therefore, no internal stress is generated in the reinforcing support 3, and cracks can be prevented from occurring.

対して傾けることもできる。 In this embodiment, the slit 4 is formed over the entire length of the reinforcing support 4, but it may also be formed over a portion of the reinforcement support 4. In addition, although the slit 4 is formed parallel to the axis of the exhaust pipe 1, it can also be inclined with respect to the axis.
又、本実施例に於ては、当該自動車用排気管は
エキゾーストマニホールドと接続できるようにな
つているが、これに限定されることなく、他の自
動車用排気管と接続することもできる。 Further, in this embodiment, the automobile exhaust pipe can be connected to an exhaust manifold, but the present invention is not limited to this, and it can also be connected to another automobile exhaust pipe.
以上述べたように、本考案によれば、自動車用
排気管にあつて、補強サポートの亀裂の発生を防
止できる効果を奏する。
As described above, according to the present invention, it is possible to prevent the occurrence of cracks in the reinforcing support in an automobile exhaust pipe.
