報参照）。In the above, the engine is usually arranged in the engine room in front of the vehicle compartment, and the rear part of the transmission extending from the rear part of the engine to the rear is arranged in the floor tunnel part formed in the front-rear direction in the center part of the floor panel. Then, as shown in FIG. 5, it is mounted and mounted on the vehicle body side member (cross member or center member) via the rear mount rubber a. (See, for example, Japanese Utility Model Publication No. 4-25378).

剪断で受けるようになっている。The above-mentioned generally used rear mount rubber a receives the weight of the rear portion of the power unit by the compression of the main rubber d and stops excessive movement of the rear portion of the power unit in the vertical direction. The structure is restricted by compression of the rubbers e and f, and the movement of the power unit in the front-rear direction, the left-right direction and the rolling direction is received by the shearing of the main rubber d.

とが望ましい。The spring characteristics of the rear mount rubber are aimed at improving the vibration absorption effect by lowering the spring constant in a normal range where the vertical movement is small, and for example, the vertical movement of the rear portion of the power unit at the time of sudden start. In a large area, it is desirable to increase the spring constant to regulate the movement of the rear part of the power unit.

できない、という課題を有している。For that purpose, the spring constant of the main rubber d must be lowered and the spring constants of the stopper rubbers e and f must be increased. However, in the above-mentioned conventional rear mount rubber a.
Since the main rubber d and the stopper rubbers e and f are simultaneously vulcanized and molded, it is very difficult to tune the spring constants of the main rubber d and the stopper rubbers e and f due to the rubber hardness. Therefore, as shown by the chain line in FIG. 4, the spring constant in the normal range (that is, the spring constant of the main rubber d) cannot be lowered so much that the spring constant in the excessive movement range of the rear part of the power unit is reduced. There is a problem that (that is, the spring constants of the stopper rubbers e and f) cannot be made too high.

Since it has a structure that is received by shearing, the spring constant is low,
There is a problem that the rearward movement of the power unit during a frontal collision is large.

A bolt extending downward is fixed to a bracket fixed to the side member and fixed to the rear portion of the power unit, the bolt is inserted and fixed in the inner cylinder of the bush, and the rear portion of the power unit is fixed to the elastic member of the bush. It is also characterized in that it is attached to and supported by the vehicle body side member via. The first stopper rubber that restricts the excessive upward movement of the rear portion of the power unit is provided on the stopper bracket fixed to the lower end portion of the bolt, and the second stopper rubber that restricts the excessive downward movement of the rear portion of the power unit.

当りが発生したり脱落したりする虞れはない。As described above, the vertical movement of the rear portion of the power unit in the normal range is received by the shear deformation of the elastic material of the bush, and the excessive movement is received by the compression deformation of the first and second stopper rubbers which are separate parts. Therefore, the optimal tuning of the spring constant is to lower the spring constant sufficiently to improve the vibration absorption effect in small movements in the normal range and to sufficiently increase the spring constant in large movement regions to regulate excessive movement. , Both rubber hardness and shape are possible. Further, the rearward movement of the power unit during a frontal collision is suppressed by the outer cylinder. Further, when the elastic material of the bush is damaged, the movement of the rear portion of the power unit is small, and there is no risk of hitting or falling off with other portions.

持構造を容易に得ることができる。In the above, the boss portion 9 of the vehicle body side member 10
By pressing the bush 1 into the outer cylinder 3
It is fixed to the vehicle body side member 10 by the friction between the outer peripheral surface of and the inner peripheral surface of the boss portion 9. Then, the bolt 6 of the bracket 5 attached to the rear portion of the power unit is inserted into the inner cylinder 2 of the bush 1, the stopper bracket 7 is inserted into the tip (lower end) of the bolt 6, and the bolt 6 is inserted into the bolt hole 7a. Then, the nut 6'is screwed into the tip of the bolt 6 and tightened. Then, the inner cylinder 2 of the bush 1 functions as an intermediate cylinder that defines the distance between the bracket 5 and the stopper bracket 7, and the upper and lower end surfaces of the boss portion 9 of the vehicle body side member 10 form the lower surface of the bracket 5 and the stopper bracket 7. The first surface and the first surface are opposed to each other with a predetermined interval.
With the upper surface of the stopper rubber 8 facing the lower end surface of the boss portion 9 and the upper end surface of the second stopper rubber 11 facing the lower surface of the bracket 5, the rear portion of the power unit is opposed to the vehicle body with a gap δ smaller than the above distance. The side member 10 can be attached and supported. By adopting such a mounting support structure of the rear portion of the power unit, the vertical displacement of the inner cylinder 2 and the outer cylinder 3 of the bush 1 is based on the vertical movement of the rear portion of the power unit within the range of the gap δ. When the elastic member 4 is deformed in the shearing direction and exceeds the range of the gap δ, the first stopper rubber 8 is attached to the lower end surface of the boss portion 9 as shown in FIG. Hit
With respect to the downward movement, the lower surface of the bracket 5 contacts the upper end of the second stopper rubber 11 as shown in FIG.
The stopper rubbers 8 and 11 are subjected to the compressive deformation, so that the spring constant is lowered in the normal region and the spring constant is increased in the region where the vertical movement is large to achieve the purpose of restricting excessive movement. be able to. Further, since the elastic material 4 of the bush 1 which is the main rubber and the first and second stopper rubbers 8 and 11 are respectively configured as separate parts, the spring constant can be tuned by the rubber hardness, The degree of freedom in tuning due to both the rubber hardness and the shape is increased. For example, as shown by the solid line in FIG. 4, the vertical spring absorption effect is increased with a lower spring constant in the normal range, and the higher spring constant in an excessive movement range. Thus, it is possible to easily obtain an ideal support structure for restricting excessive vertical movement of the rear part of the power unit.
【００１９】又、内筒２の外周が外筒３で囲まれている

筒３にて抑制される。Further, since the outer circumference of the inner cylinder 2 is surrounded by the outer cylinder 3, the rear movement of the power unit at the time of a frontal collision is suppressed by the outer cylinder 3.

ない。Furthermore, the elastic member 4 of the bush 1 is shown in FIG.
If a part is cut off as shown in (C), the bush 1
Is sandwiched between the bracket 5 and the stopper bracket 7 and the outer peripheral portion of the inner cylinder 2 is surrounded by the outer cylinder 3. Therefore, the movement of the rear portion of the power unit is not so large, and the rear portion of the power unit is not so large. There is no fear that the will drop out.

もり音発生という問題があったが、本発明ではそのよう
な虞れが全くなくなる。As described above, according to the present invention, with respect to the vertical movement of the power unit, the spring constant of the supporting portion at the rear portion of the power unit is sufficiently lowered for a small movement in the normal range to obtain a vibration absorbing effect. It is possible to improve the spring constant in a large movement region, thereby sufficiently adjusting the spring constant to restrict excessive movement, thereby enabling optimum tuning of the spring constant. Further, the rearward movement of the power unit at the time of a frontal collision can be suppressed to a small range. Furthermore, even if the elastic material of the bush is cut off, the movement of the rear part of the power unit is very small and there is no possibility of hitting or falling off other parts. Further, in the conventional structure, since the stopper bracket is fixedly mounted on the member on the vehicle body side, there is a problem that a muffled noise is generated in the vehicle due to the resonance of the stopper bracket, but the present invention eliminates such a fear at all.
