It is suspended on the vehicle body with

The main body of the vibration isolator 4 is a cushioning rubber 4a made of an elastic material, and as shown in FIG.
Face plates 4b and 4c are fixed substantially parallel to both end faces of a, respectively, and bolts 4d and 4c are respectively attached to each face plate 4b and 4c.
4e is fixed and protrudes substantially vertically.

When mounting the engine 1, while suspending the engine 1, the mounting hole 2b provided in the mounting seat 2a and the mounting hole 7 provided in the flange 7a are sequentially opened.
Insert the bolts 4d and 4e into the mounting legs 2, respectively.
By bringing the face plates 4b and 4c of the vibration isolator 4 into contact with the mounting seat 2a and the flange 7a of the bracket 7, and firmly screwing and tightening the bolts 4d and 4e with the nuts 8a and 8b, respectively, the vibration isolator Engine 1 is supported via 4.

When lowering the engine 1, remove the nuts 8a and 8b, tilt the engine 1 while lifting it, and tighten the bolts 4d and 4e into the mounting holes 7b of the flange 7a of the bracket 7 and the mounting holes 2a of the mounting legs 2. 2b and space plates 4b and 4c of the vibration isolator 4 from the mounting seat 2a of the mounting leg 2 and the flange 7a of the bracket 7, the engine 1 can be removed and lowered.

[Problems with conventional technology]

As described above, the engine 1 may have to be taken down for maintenance or repair, even though it is the heaviest vehicle accessory. In addition, the vibration isolator 4
As shown in FIG. 1, in order to properly perform functions such as supporting and vibration-proofing the engine 1, they are arranged at an angle. Furthermore, this section of the support device is very narrow in order to benefit from space savings.

Therefore, when loading and unloading the engine unit, it is very difficult to fit and remove the bolts 4d and 4e into the mounting holes 2b and 7b.
As a result, it is possible to work by loosening or removing the mounting bolts 2d and 2e of the engine side mounting part 2c of the mounting leg 2, but since there is no space,
This task is also not easy. For this reason, engine 1
When loading and unloading, please pry between the mounting legs 2, vibration isolator 4, and bracket 7, and remove the vibration isolator 4 and bolts 4.
d, 4e, etc. may be damaged.

Furthermore, when replacing the vibration isolator 4, the engine unit must be lifted considerably to obtain space for the replacement. In order to lift it in this way, other connecting members such as the torque bush and torque rod must also be removed, which poses the problem of requiring extra effort.
