５とにより構成している。 Generally, such an exhaust pipe mounting device, as shown in FIG. tube 3
A connecting member on the exhaust pipe side, such as the rod 4, which is fitted and connected to the other end of the elastic member 2, and abutting against the surface of the elastic member 2 in order to limit deformation of the elastic member, especially the portion on the rod 4 side. However, it is constituted by a stopper, for example, an iron plate 5, provided with a slot 6 that allows movement of the rod 4 to a certain extent.

したものである。 The function of this exhaust pipe mounting device is to connect the exhaust pipe to the vehicle body, and to allow the vibration of the exhaust pipe when the rolling or vibration that occurs in the engine body due to engine operation, so-called "engine roll" is transmitted to the exhaust pipe. The elastic member of this mounting device absorbs vibrations to prevent vibrations from being transmitted directly from the exhaust pipe mounting device to the vehicle body, and the stopper prevents the exhaust pipe from being excessively displaced and interfering with other components. be.

口である。 However, as shown by the solid line in Figure 2, the layout of conventional exhaust pipe mounting devices is such that when viewed from the side of the vehicle, the connection position on the exhaust pipe side is directly below the connection position on the vehicle body side, or In consideration of this, the vehicle body side connecting member and the exhaust pipe side connecting member were relatively arranged so that they were located somewhat forward. FIG. 2 is a sectional view taken along the line -- in FIG. 1, and reference numeral 7 indicates an opening provided in the mounting rubber to facilitate deformation of the mounting rubber.

系においてこの問題点が著しい。 However, with this layout, in the case of a transverse engine FF vehicle, the rolling axis of the engine (in the direction of double-headed arrow A) is perpendicular to the axis of the exhaust pipe, as shown in Figure 3. The roll causes the exhaust pipe to vibrate in the direction of arrow B, causing the second
The state shown by the dashed line in the figure is reached. As is clear from Figure 2, the amount of expansion and contraction of the elastic member, that is, the mounting rubber 2, is large, and the mounting rubber exerts a reaction force on the exhaust pipe, so the strength of not only the mounting rubber but also the exhaust pipe itself must be high. Otherwise, the cost will increase. This problem is particularly noticeable in exhaust systems that incorporate flexible tubes used to prevent the generation of noise and vibrations.
本発明は、このような従来の問題点に着目して

る。 The present invention has been made by focusing on such conventional problems, and is designed to reduce the reaction force of the mounting rubber in the direction of displacement of the exhaust pipe due to the engine roll. In order to lay out the exhaust pipe mount so as not to restrict it, when the engine is not operating, the connection position of the exhaust pipe side connecting member with the elastic member is rearward with respect to the vehicle body relative to the connection position of the body side connecting member with the elastic member, and By configuring and arranging the vehicle body side connecting member and the exhaust pipe side connecting member so that the line connecting the side connecting position and the exhaust pipe side connecting position is approximately perpendicular to the displacement direction of the exhaust pipe due to engine roll. The purpose is to solve the above problems.
以下、本発明を図面に基づいて説明する。 Hereinafter, the present invention will be explained based on the drawings.
第４図は本発明の一実施例を示す図である。 FIG. 4 is a diagram showing an embodiment of the present invention.
この実施例は、第２図に示すものとほぼ同一で

（第４図実線部参照）。 This embodiment is almost the same as that shown in FIG. 2, but the layout of the connecting positions of the vehicle body side connecting member 1 and the exhaust pipe side connecting member 4 in the exhaust pipe mounting device is different. That is, according to the present invention, the connection position on the vehicle body side and the connection position on the exhaust pipe side are arranged relative to each other in a direction substantially perpendicular to the direction of displacement of the exhaust pipe due to engine roll when the engine is not operating, and the connection position on the exhaust pipe side Each connecting member is configured and arranged so that the connecting position thereof is located at the rear of the connecting position on the vehicle body side (see the solid line section in Fig. 4).

レイアウトの場合と比べると極く僅かである。 According to this configuration, when the engine roll rotates in both forward and reverse directions, as shown by the dashed line in FIG.
As the exhaust pipe moves, the mounting rubber only expands without contracting. This amount of expansion is extremely small compared to the conventional layout shown in FIG.

プにならないという効果がある。 As explained above, in the present invention, when the engine is not operating, the connecting position of the exhaust pipe side connecting member with the elastic member is rearward with respect to the vehicle body with respect to the connecting position of the vehicle body side connecting member with the elastic member, and on the vehicle body side. The vehicle body side connection member and the exhaust pipe side connection member are configured and arranged so that the line connecting the connection position and the exhaust pipe side connection position is almost perpendicular to the displacement direction of the exhaust pipe due to engine roll, so that the engine can be operated easily. The amount of deformation of the mounting rubber inside is reduced, and the reaction force exerted by the mounting rubber on the exhaust pipe is also reduced.
There is no need to increase the strength requirements of the mounting rubber, exhaust pipe, and flexible tube, which has the effect of not increasing costs.
更に、取付ラバーの反力が小さく、エンジンロ
ールに対する抵抗とならないため、エンジンロー
ルを排気管マウント部で規制することなく、自由

なくなる。 Furthermore, since the reaction force of the mounting rubber is small and does not create resistance to the engine roll, the engine roll can be rolled freely without being restricted by the exhaust pipe mount, and therefore noise and vibrations are removed from the exhaust pipe mount. There is no longer any information to be sent to the car body.
