BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle exhaust pipe support member interposed between an automobile exhaust pipe and a vehicle body to elastically support the exhaust pipe.

[0002]

2. Description of the Related Art A ring-shaped exhaust pipe support member (1 ') is interposed between an exhaust pipe of an automobile and a vehicle body as shown in FIG. It is prevented from being transmitted to. The exhaust pipe supporting member (1 ') is entirely made of rubber, and as shown in FIG. 5, an exhaust pipe mounting portion (16) having a hole (15) for fitting the mounting arm (3) on the exhaust pipe side. And a vehicle body mounting portion (18) provided with a hole (17) into which the vehicle-side mounting arm (7) is inserted, and are integrally disposed on the annular connecting portion (19) so as to face each other. Have.

[0003] That is, the exhaust pipe support member (1 ') reduces the vibration of the exhaust pipe suspended from the vehicle body by the support member.
The annular connecting portion (19) is prevented from being absorbed and transmitted to the vehicle body by being elastically deformed.

[0004]

As described above, the exhaust pipe supporting member reduces the vibration from the exhaust pipe as described above, while the exhaust pipe supporting member is largely separated from the exhaust pipe by inertia when the vehicle suddenly starts or brakes. When the force is applied, the support member is connected to the exhaust pipe mounting portion (16) and the vehicle body mounting portion (18) as shown by the arrow in FIG.
Are compressed in the direction of approach. In this case, the support member presses the opposed end portions (20) and (20) of the exhaust pipe mounting portion (16) and the vehicle body mounting portion (18) which are opposed to each other and presses against each other, whereby an inertial force acting on the exhaust pipe is obtained. In the conventional exhaust pipe supporting member, as shown in the figure, the exhaust pipe mounting portion (16) and the vehicle body mounting portion (18) are connected to the annular connecting portion (19) by these sides. Because the parts are connected only at the parts, the relative positions of the mounting parts (16) and (18) are deviated due to vibration of the exhaust pipe itself, vibration from the road surface, and the like, and the opposed ends are correctly pressed against each other. However, the compression deformation of the support member causes a problem in that the function as a stopper is impaired, and the durability of the support member itself is affected.

[0005] The present invention has been made in view of the above-described situation, and by finding a new structure for the exhaust pipe supporting member, it is possible to reduce the inertial movement of the exhaust pipe due to sudden start or sudden braking. In the above-mentioned supporting member, it is an object of the present invention to accurately stabilize the mounting by pressing the mounting portions to each other, and to simultaneously improve the durability of the supporting member itself by the stable deformation.

[0006]

The vehicle exhaust pipe supporting member according to the present invention, which meets the above object, is characterized by an exhaust pipe mounting portion provided with a hole into which a mounting arm on the exhaust pipe side is inserted. An exhaust pipe supporting member in which a vehicle body mounting portion having a hole into which a mounting arm on the vehicle body is inserted is provided integrally with an annular connecting portion made of an elastic material so as to face each other. each opposite end of the tube mounting portion and the vehicle body mounting portion, a beam portion which respectively both ends was Watarura to the connecting portion,
Substantially allowed parallel formed at predetermined intervals between the beam part, the
Pressure contact between the exhaust pipe mounting part and the vehicle body mounting part is made via these beams
It is made to be done . It is also preferable that both ends of the groove-shaped gap formed between the beam portions are formed so as to be substantially circularly expanded at both ends, so that when the support member is pulled, the groove-shaped gap is formed. It is possible to alleviate the concentration of the tearing stress acting on the end of the substrate.

[0007]

In the exhaust pipe supporting member of the present invention having the above-described structure, the connecting portion is provided by two beams provided at the opposite ends of the exhaust pipe mounting portion and the vehicle body mounting portion, respectively. The parts are reinforced to hold the relative positions of the above-mentioned mounting parts correctly even for various vibrations, and the mounting parts can be accurately pressed against each other via the beam part even for the inertial movement of the exhaust pipe. , and the addition, the pressure is from being made through the beam portion which is provided substantially in parallel as described above, as possible out to receive the compression by inertial movement of the exhaust pipe in a stable state by a wide receiving area .

Further, in this embodiment, the support member (1) is integrally formed of EPDM rubber (ethylene-propylene-non-conjugated diene terpolymer), and has appropriate hardness and elasticity.

The exhaust pipe supporting member according to the embodiment of the present invention having the above-described structure is interposed between the vehicle body and the exhaust pipe in a manner as shown in FIG. 4, for example. The portion (10) is prevented from being absorbed by the elastic deformation and transmitted to the vehicle body side. As described above, the inertia force acts on the exhaust pipe due to the sudden start or sudden braking of the vehicle, and a moving force acts on the exhaust pipe. In the exhaust pipe support member (1) of the present invention, the exhaust pipe is mounted. A connecting part (10) is provided at each of the opposed ends (13) of the part (5) and the vehicle body mounting part (9).
