Description

[Detailed Description of the Invention] Industrial Field of the Invention The present invention has a flexible pipe formed to absorb engine vibration transmitted to an exhaust pipe, encloses a wire mesh for protection, and the exhaust pipe is connected to the ground. In order to protect the flexible pipe from damage due to contact, the lower side of the heat protector that covers the exhaust pipe is extended to cover and protect the front part of the outside of the wire mesh. Also used as a flexible pipe protector. It relates to a heat protector.

2. Description of the Related Art Conventionally, a heat protector has been attached to the exhaust pipe of an engine with a band or the like in order to shield heat. Further, a flexible pipe is connected to the exhaust pipe so as not to transmit vibrations from the engine, and a wire mesh is encapsulated to protect the flexible pipe. As shown in FIGS. 3 and 4, the exhaust pipe (1) was connected to the flexible pipe (3) enclosing the wire mesh (2) and was suspended from the vehicle body via the rubber ring (4). A heat protector (5 ') was encapsulated in the exhaust pipe (1) for heat insulation and fastened by a band (6) or the like.

The problem to be solved by the invention is that the exhaust pipe (1) disposed on the lower surface of the vehicle body may come into contact with the ground when driving on a rough road, and this repeated contact breaks the wire mesh (2). However, there was a risk that the flexible pipe (3) would also be damaged and the exhaust gas would leak.

Therefore, the present invention extends the lower side of the heat protector a little to prevent the ground from contacting the exhaust pipe and breaking the wire mesh or breaking the flexible pipe on a bad road, and also used as a protector for preventing damage to the flexible pipe. The purpose is to

MEANS FOR SOLVING THE PROBLEMS The present invention provides a wire mesh encased for protecting a flexible pipe arranged to absorb vibration transmitted to an exhaust pipe of an engine, and a heat shield for the exhaust pipe. In a structure of an exhaust pipe having a heat protector encased in, a heat protector extending downward is formed, and an extended front part of a wire mesh enclosing a flexible pipe is encased by the extended part of the heat protector. This is a protected heat protector that also serves as a flexible pipe protector.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the lower side of a vehicle body in which an exhaust pipe is arranged, and FIG. 2 is an exhaust gas in which a heat protector also serving as a flexible pipe protector is arranged. The structure of the tube is shown.

As shown in FIGS. 1 and 2, a heat protector (5) is encapsulated to shield the exhaust pipe (1) from the engine E disposed under the vehicle body, and the wire mesh (2) is covered. A flexible pipe (3) that absorbs the vibration of the engine E transmitted by the enclosed exhaust pipe (1) is connected to the exhaust pipe (1), and the ground comes into contact on a bad road or the like to break the wire mesh (2). Or the lower part of the heat protector (5) is extended so as not to damage the flexible pipe (3), and the wire mesh (2) enclosing the flexible pipe (3) by the extended portion (5a). Is protected by enclosing the front part (2a) on the outside thereof.

In the figure, (6) is a band for fastening the heat protector (5) to the exhaust pipe (1), and (4) is a rubber ring,
The exhaust pipe (1) is suspended from the vehicle body via the rubber ring.

Furthermore, in the figure, (7) is a muffler.

Therefore, the extension portion formed below the heat protector (5) enclosing the exhaust pipe (1) of the engine E for heat shielding.
Due to (5a), the wire mesh (2) encapsulated to prevent damage to the flexible pipe (3) connected to absorb vibration from the engine is torn by repeated contact with the ground, and further flexible pipe ( Protect the wire mesh (2) and flexible pipe (3) so that even 3) is not broken and exhaust gas does not leak.

Effect As a result, the present invention prevents the wire mesh and the flexible pipe from being broken by the extension part of the heat protector that also serves as the flexible pipe protector even when the exhaust pipe comes into contact with the ground when driving on a rough road. As a result, there is no exhaust gas leakage, and even if the extension part is damaged by contact with the ground, it can be repaired at a lower cost than repairing a wire mesh with a high unit price, and repair costs can be reduced.
