【考案の詳細な説明】 〔産業上の利用分野〕 本考案は自動車のエンジンの排気系に適用される支持
構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a support structure applied to an exhaust system of an automobile engine.
従来の自動車の排気系の支持構造を第３図に示す。図

方に差出された排気管である。FIG. 3 shows a conventional structure for supporting an exhaust system of an automobile. In the figure, (1) is a vehicle floor, (2) is a cross member,
(3) is a short pipe that is vertically welded along the side surface of the cross member (2), and a pair of upper and lower mounting holes (41),
The mounting hole (4) on the upper side of the mounting rubber (4) having the (42)
1) Insert the short pipe (3) into the lower mounting hole (42).
A short pipe (6) extending upward from the exhaust muffler (5) is inserted into the exhaust pipe. (7) is an exhaust pipe extending rearward from the muffler (5).

（２）の側面に沿って垂直に溶接されるために排気系の
振動がクロスメンバー（２）の側面で膜振動となって車
体にそのまゝ伝達されるので、こもり音の原因となって
おり、また支持強度も充分とは言えない。In the above-described conventional configuration, since the short pipe (3) is vertically welded along the side surface of the cross member (2), the vibration of the exhaust system becomes a film vibration on the side surface of the cross member (2) and remains on the vehicle body.さ れ る Because it is transmitted, it causes a muffled sound and the supporting strength is not enough.

るものである。[Means for Solving the Problems] The present invention provides a means for solving the above-mentioned conventional problems, in which a short pipe (3) A
And the short pipe (3) A is connected to an elastic bracket (4) A having a pair of upper and lower mounting holes (41) A and (42) A.
The lower mounting hole (4) is inserted into the upper mounting hole (41)
2) A short pipe (6) A extending from the exhaust system (5) A is inserted into A, and the short pipe (6) A has a substantially 7 shape. The lower end of the inclined side (62) A, which is inserted into the lower mounting hole (42) A of the elastic bracket (4) A and bent downward from one end of the upper side (61) A, is connected to the exhaust system (5). A is to provide a support structure for the exhaust system (5) A connected to A.
本考案では短パイプ（３）Ａはクロスメンバー（２）
Ａに横方向に貫着されているのでその取付構造には剛性

に変動することおよび該短パイプ（３）Ａの中空構造に
もとづく弾性的な撓みによって吸収されてしまう。In the present invention, the short pipe (3) A is a cross member (2).
A is rigidly attached to the mounting structure because it is laterally attached to A. The vibration transmitted from the exhaust system (5) A via the mounting rubber (4) A is elastic because the inclination angle of the inclined side (62) A of the short pipe (6) A having a substantially seven shape is based on the hollow structure. And the short pipe (3) A is absorbed by the elastic deformation based on the hollow structure.
したがって本考案では、排気系の振動がクロスメンバ

短パイプは夫々中空構造によって殆ど永久歪を生ずるこ

る。Therefore, in the present invention, since the vibration of the exhaust system is absorbed by the short pipe on the cross member side and is not transmitted to the vehicle body as it is, the muffled sound based on the vibration of the vehicle body is significantly reduced, and the support strength of the exhaust system is also improved. . Each of the short pipes hardly causes permanent distortion due to the hollow structure, and maintains good vibration absorption for a long time.

ラー（５）Ａに接続されている。The present invention will be described with reference to an embodiment shown in FIG. 1 and FIG. 2. A cross member (2) A is disposed on the floor behind the vehicle body (1) A, and a rear portion of the cross member (2) A. In FIG. 2, a short pipe (3) A is attached in a lateral direction, and the short pipe (3) A is inserted into an upper mounting hole (41) A of a mounting rubber (4) A as an elastic bracket shown in FIG. And a lower mounting hole (42) of the mounting rubber (4) A.
A is fitted with a short pipe (6) A extending upward from a muffler (5) A as an exhaust system. (7) A is an exhaust pipe extending rearward from the muffler (5) A. The short pipe (6) A comprises an upper side (61) A and an inclined side (62) A bent downward from one end of the upper side (61) A, and the upper side (61) A is provided with the mounting rubber. (4) The lower side of the inclined side (62) A is connected to the muffler (5) A by being inserted into the lower mounting hole (42) A of A.

構造であるから上記弾性変形によって永久歪を殆ど生じ
ない。In the above configuration, since the short pipe (3) A is laterally penetrated to the cross member (2) A, the rigidity of the mounting structure between the short pipe (3) A and the cross member (2) A is reduced. Vibration from the muffler (5) A is reduced by the mount rubber (4) A via the short pipe (6) A on the muffler (5) A side, and then reduced by the cross member (2).
It is transmitted to the short pipe (3) A on the A side. At this time, the short pipe (6) A is elastic due to the hollow structure of the short pipe (6) A when the inclination angle of the inclined side (62) A is between θ and θ ′ as shown in FIG. The short pipe (6) A is elastically deformed between the solid line state and the dotted line state, and the direction of the vibration is substantially perpendicular to the axial direction of the short pipe (3) A. (3) A further absorbs and reduces the vibration due to the elastic bending caused by the hollow structure. Therefore, the vibration transmitted to the vehicle body via the cross member (2) A is almost completely absorbed and reduced, and the muffled sound based on the vibration of the vehicle body is greatly reduced. Since the short pipes (3) A and (6) A have a hollow structure, permanent deformation hardly occurs due to the elastic deformation.
