用されている。(Prior Art) In a general automobile, an elastic body such as rubber for vibration isolation is mounted between upper and lower metal seat plates arranged substantially in parallel in order to prevent engine vibration from being transmitted to a vehicle body. Using a plurality of vibration isolating members (engine mounts, insulators) having the above structure, the lower seat plates of the vibration isolating members are arranged and fixed at predetermined positions of a vehicle body structure, for example, a cross member. An engine support structure for fixing an engine at a predetermined position and fixing the engine to a vehicle body via the plurality of vibration isolating members is applied.

力が大きくなる等、問題であった。However, when the engine is supported via the vibration isolating member, the elastic body of the vibration isolating member may be cut or moved up and down when a large acceleration is applied to the engine in the traveling direction of the vehicle, such as during an automobile collision or sudden deceleration. The elastic body may come off from the seat plate of the engine, causing the engine to move largely in the direction of travel of the vehicle body, causing a fire due to falling off of the fuel hose, the crankshaft, transmission, or parts around the engine, etc. This is a problem that may cause damage. In particular, in a cab-over vehicle such as a one-box car, the engine is located immediately below the seat, so that the engine movement has an adverse effect, for example, the impact force applied to the occupant due to the impact from the engine side in addition to the impact at the time of a vehicle collision.

Since the stopper that regulates the amount of engine movement is formed in a rectangular frame shape, it is not necessary to fix the stopper to the cross member, and the frame side of the stopper is engaged with the cross member side of the vehicle body at a predetermined interval. Therefore, the stopper does not normally operate, and the stopper does not impair the vibration-proofing properties of the vibration-proof member, thereby preventing the generation of vibration and abnormal noise. In addition, since the frame side of the stopper is engaged with the cross member on the side where the reinforcing bracket is provided, the engine can be received with rigidity at the time of a vehicle collision or the like. In addition, since the engine side engaging portion and the engine fixing portion of the stopper are formed integrally with the upper side seat plate of the vibration isolator, the structure is simplified,
The number of parts and the number of welding points are greatly reduced, and cost reduction can be easily achieved.
