にある。In order to achieve the above purpose, this invention is characterized by a pair of left and right frames that make up the vehicle body arranged in the front and back direction, an engine arranged between both frames, and a front side of the engine of both frames. The parts are connected with a bracket, and a front support part that supports the engine rotatably around the front support pin in the longitudinal direction is interposed between the horizontal center of both the bracket and the front end of the engine. In a tractor that has a pair of left and right rear support parts interposed between the side and each frame, the engine is rotatably supported around a lateral rear support pin whose axes coincide with each other. A cylindrical body is fitted over the support pin and is made of an elastic material and allows rotation of the engine around the rear support pin by elastic deformation of the cylinder body, and is provided on each rear support portion to protrude rearward from the rear side of the engine. A support arm whose rear part is pivotally supported on the frame by a rear support pin, is made of an elastic material, and allows rotation of the engine around the front support pin by elastic deformation of the middle part in the longitudinal direction, and is fitted into the rear support pin. and a cylindrical body interposed between the rear part of the support arm and the frame and made of an elastic material, which cooperates with the support arm by elastic deformation to allow rotation around the front support pin of the engine. It is in.

一例であり、１は独自に構成された車体で左右の主フレ
ーム２，２と前後の連結フレーム３．３とで平面が長手
枠状に形成されている。Figures 1 to 6 show an example of an agricultural tractor, in which 1 is a uniquely constructed body consisting of left and right main frames 2, 2, and front and rear connecting frames 3, 3, and the plane is shaped like a longitudinal frame. is formed.
この車体１の前部に操向自在な前輪４を装備し、又後部
にはデフ装置５を介して後輪６が駆動自在に装備されて
いる。A steerable front wheel 4 is provided at the front of the vehicle body 1, and a driveable rear wheel 6 is provided at the rear via a differential device 5.
これら前後間には、ミッションケース７を後部に付設し
たエンジン８が搭載されており、この搭載が若干後傾し
た姿勢でかつ三次元的に回動が許ノされる状態として弾
支されている。An engine 8 with a mission case 7 attached to the rear is mounted between the front and back, and this mounting is supported in a slightly backward-leaning position and is allowed to rotate in three dimensions. .
このための具体的構造としては、まず両生フレーム２，
２をコ型チャンネル材で形成しこれら双方の溝９が互い
に内向きとなるように配置すると共に、これらで形成さ
れた枠を介して、前部支。As for the specific structure for this purpose, first, the amphibious frame 2,
2 is made of a U-shaped channel material and arranged so that the grooves 9 of both of them face inward, and the front support is attached via a frame formed of these.
承部ａと後部支承部す、 ｂを構成する。It consists of a bearing part a, a rear bearing part A, and a rear bearing part B.
前部支承部ａは、両生フレーム２，２間に横設された前
後２枚のブラケツＮＯ，１０に前後方向の前部支持ピン
として示す中央支持ピン１１を備え、このピン１１回り
に前部弾支筒１２を備えつけると共に、エンジン８の下
部に突設された支承板１３の下端を弾支筒１２回りに回
動自在とすることで構成されている。The front support part a is provided with a central support pin 11 shown as a front support pin in the front and rear direction on two front and rear brackets NO, 10 installed horizontally between the two-sided frames 2, 2, and around this pin 11, the front part In addition to being equipped with a bullet support tube 12, the lower end of a support plate 13 protruding from the lower part of the engine 8 is configured to be freely rotatable around the bullet support tube 12.
こうしてエンジン８は前端下部中央を支点とした左右に
回動できしかも弾支されるわけである。In this way, the engine 8 can rotate left and right around the center of the lower front end as a fulcrum, and is supported elastically.
一方後部支承部す、 ｂは、主フレーム２の内部空間
を利用して左右対称に配備され、これがミッションケー
ス７の両側に対応する位置とされている。On the other hand, the rear support portions S and B are arranged symmetrically using the internal space of the main frame 2, and are located at positions corresponding to both sides of the mission case 7.
この支承部すでは、主フレーム２の側壁から内向きに受
筒１４を突設しその内部にゴム部製の弾支ゴム片１５を
嵌装させ、この中心を介して後部支持ピン１６を嵌挿さ
せである。In this support part, a receiving cylinder 14 is provided inwardly protruding from the side wall of the main frame 2, and a resilient rubber piece 15 made of a rubber part is fitted inside the receiving cylinder 14, and a rear support pin 16 is fitted through the center of the receiving cylinder 14. I have to insert it.
このピン１６は左右をなして同心状に対応するものとさ
れ、各内端部を、エンジン８から突設した支持アーム１
７．１７の後端ボス部１７ Ｃに連結しである。The pins 16 correspond concentrically on the left and right, and each inner end is connected to a support arm 1 protruding from the engine 8.
7.17 is connected to the rear end boss portion 17C.
同アーム１７は、前端に扁平部１７ ａを備えこれとボ
ス部１７ Ｃとの前後間を丸棒状のツイスト部１７ｂと
して所要長のトーションバーを形成したものであって、
前記扁平部１７ ａを介してエンジン８にボルト止めさ
れ又ボス部１７ Ｃを介して後部支持ピン１６に夫々枢
結されている。The arm 17 has a flat part 17a at the front end, and a round bar-shaped twisted part 17b between the flat part 17a and the boss part 17C, forming a torsion bar of a required length.
It is bolted to the engine 8 via the flat portion 17a and pivotally connected to the rear support pin 16 via the boss portion 17C.
こうして後部両脇と前部中央の合計３点でもってエンジ
ン８が支持され、前部中央を基準とすれば中央支持ピン
１１が前後方向をなすのでエンジン８はこれを中心とし

バーとして作用するので弾支ゴム片１５，１５の弾性変
形と共働してエンジン８は自由に弾性的回動をすること
ができ、又前後方向についても支持アーム１７その他の
弾性片によって自由な動作をする。In this way, the engine 8 is supported by a total of three points on both sides of the rear and the center of the front. If the center of the front is used as a reference, the center support pin 11 forms a longitudinal direction, so the engine 8 can swing left and right around this. At this time, the support arm 17 acts as a dowel bar, so that the engine 8 can freely rotate elastically in conjunction with the elastic deformation of the elastic support pieces 15, 15, and also in the front-rear direction. The support arm 17 and other elastic pieces allow free movement.
これによりエンジン８は複合的な方向に弾性動できるこ
ととなり、エンジン８での振動をこれによって充分吸収
緩和できるものとなる。This allows the engine 8 to move elastically in multiple directions, thereby making it possible to sufficiently absorb and alleviate vibrations in the engine 8.
尚、支持アーム１６によって止着した場合、エンジン８
を脱着するのが非常に至便となる。In addition, if the engine 8 is stopped by the support arm 16,
It is very convenient to put on and take off.

間隔を大とする必要がなく、車体を構成する両フレーム
間隔の拡大によって、トラクタ上の運転者の視界が狭く
なったりすることがない。This invention is constructed as described above, and each support part can be easily constructed, and the rotation range around the front support pin of the engine is achieved by elastic deformation of the front-rear midway part of the support arm of each rear support part and the cylindrical body. can be made larger, and the vibrations of the engine can be better mitigated and absorbed, and even though each rear support is equipped with a support arm as mentioned above,
In order to increase the amount of deformation of the support arm, since the support arm is provided to protrude rearward from the rear side of the engine, and the support arm is not disposed laterally between the lateral center of the engine and the frame, Even if the length is increased, there is no need to increase the distance between the two frames, and the field of view of the driver on the tractor will not be narrowed due to the increase in the distance between the two frames constituting the vehicle body.
尚、前記支持アーム１７は、板バネによってもよい。Note that the support arm 17 may be a plate spring.
又、後部支承部すは、車体１内に備わると車体中を狭く
することができるが、この際主フレーム２は第７図示の
如く四角筒のものとしてもよい。Further, if the rear support portion is provided inside the vehicle body 1, the interior of the vehicle body can be narrowed, but in this case, the main frame 2 may be a square tube as shown in FIG.
更に上記の場合エンジン８はプロペラシャフト１８の屈
折角を小さくすべく後傾姿勢として搭載されているが水
平でも同効を奏す。Further, in the above case, the engine 8 is mounted in a backward tilted position to reduce the angle of refraction of the propeller shaft 18, but the same effect can be achieved even if the engine 8 is mounted horizontally.
