SUMMARY OF THE INVENTION The present invention is an engine mount bracket mounted on the front portion of a side rail that is groove-shaped toward the inside in the vehicle width direction. A base plate that is installed so as to close the opening and defines an installation space with a closed cross section together with the side rail; and a bracket body that is installed on the vehicle width direction inner side surface of the base plate and receives the engine mount. It is a feature.

In this way, since the bracket main body for receiving the engine mount is arranged outside the wiring space defined by the side rail and the base plate, the bracket main body is occupied. It is possible to use the entire wiring space for wiring harnesses and piping without considering the space.

Further, in the present invention, it is preferable that the base plate is divided into upper and lower parts, and the bracket body is supported by one of the divided plates.

In this way, the height dimension of the base plate can be adjusted by appropriately adjusting the connecting positions of the upper and lower split plates, and the base plate need not be manufactured with high accuracy on the side rail side. It becomes possible to install the engine mount bracket.

Here, when the base plate is divided into upper and lower parts, for example, the upper end portion of the upper divided plate is superposed on the lower surface of the upper flange of the side rail and fastened, and the lower end portion thereof is bent downward to form a lower side. Of the lower split plate, the upper end of the lower split plate is connected to the lower end of the upper split plate to extend downward, and the lower end thereof is outward in the vehicle width direction. It may be formed so as to be bent and overlapped and fastened to the upper surface of the lower flange of the side rail.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show an example of an embodiment for carrying out the present invention, and the portions denoted by the same reference numerals as those in FIGS. 4 and 5 represent the same parts.

In this embodiment, the side rails 2 and 2 (in which only one side rail is shown in FIGS. 1 to 3) are grooved toward the inside in the vehicle width direction. The engine mount bracket 7 is composed of a base plate 8 and a bracket body 9 as described in detail below.

That is, the engine mount bracket 7 shown here is mounted on the inner side of the side rail 2 in the vehicle width direction so as to close the groove-shaped opening, and together with the side rail 2, the installation space S having a closed cross section. Base plate 8 that defines the
And a bracket body 9 mounted on the inner surface of the base plate 8 in the vehicle width direction to receive an engine mount (not shown)
In addition, the base plate 8 is divided into an upper split plate 8a and a lower split plate 8b at a relatively high position.

Then, the upper end of the upper split plate 8a is overlapped with the lower surface of the upper flange 2a of the side rail 2 and fastened, and the lower end thereof is bent downward to form a connecting portion with the lower split plate 8b. The lower split plate 8b is connected to the upper end of the upper split plate 8a to extend downward, and the lower end is bent outward in the vehicle width direction to form a side rail. The upper surface of the flange 2a at the lower part of 2 is overlapped and fastened.

Thus, in this way, the bracket body 9 for receiving the engine mount is arranged outside the wiring space S defined by the side rail 2 and the base plate 8. It is possible to use the entire wiring space S for wiring the harness 4 and the piping 5 without considering the space occupied by the bracket body 9.

Moreover, in this embodiment, the base plate 8 is divided into an upper divided plate 8a and a lower divided plate 8b, and the bracket main body 9 is mounted by the lower divided plate 8b. Therefore, when fastening the upper and lower split plates 8a, 8b,
For example, if the fastening hole is a long hole extending in the vertical direction, etc., the upper and lower overlapping amounts of the lower end portion of the upper split plate 8a and the upper end portion of the lower split plate 8b are appropriately adjusted to fasten each other. Side rail 2
It is possible to easily mount the engine mount bracket 7 without manufacturing the base plate 8 with high accuracy on the side.

That is, in order to secure the wiring space S as wide as possible, the base plate 8 having a groove shape that naturally faces the groove shape of the side rail 2 as shown in FIG. However, in this case, if the base plate 8 is manufactured as an integrally molded product, the distance between the upper and lower flanges 2a of the side rail 2 and the height of the base plate 8 will increase. If the dimensions are not equal to each other with high accuracy, good mounting cannot be realized, which may cause a rise in the manufacturing cost of the engine mount bracket 7 and a decrease in assembly workability. Therefore, the base plate 8 is divided into upper and lower parts. The height dimension can be adjusted.

In order to install the harness 4 and the pipes 5 in the installation space S, after completing the installation space S having a closed cross section, a large number of harnesses 4 and pipes 5 are arranged in the installation space S together with the coupler. Since it is difficult to pass it through, as shown in FIG. 3, at least before mounting the division plate 8b, the harness 4 or the pipe 5 is inserted from the gap of the groove-shaped opening of the side rail 2 which is not completely closed yet. It is better to let them be accommodated.

Therefore, according to the above embodiment, the entire wiring space S can be used for the wiring of the harness 4 and the piping 5 without considering the space occupied by the bracket body 9, so that the harness 4 or the piping 5 can be used. Since the installation space S for installing 5 can be secured larger than the conventional one, and the height of the base plate 8 can be adjusted vertically, the side rail 2 side can be adjusted. It is possible to easily mount the engine mount bracket 7 without manufacturing the base plate 8 with high accuracy, and it is possible to avoid a rise in manufacturing cost of the engine mount bracket 7 and a decrease in assembly workability.

The engine mount bracket of the present invention is not limited to the above-mentioned embodiment, and the upper and lower split plates may be attached with the bracket main body by lowering the vertical split position of the base plate as compared with the illustrated example. Needless to say, various changes can be made without departing from the scope of the present invention.

According to the engine mount bracket of the present invention described above, various excellent effects as described below can be obtained.

(I) According to the invention described in claim 1 of the present invention, the entire wiring space can be used for wiring harnesses and pipes without considering the space occupied by the bracket body. It is possible to secure a larger wiring space for wiring harnesses and pipes than before.

(II) According to the second or third aspect of the present invention, since the height of the base plate can be adjusted by dividing the base plate into upper and lower parts, the side rail side can be adjusted with high accuracy. It is possible to easily mount the engine mount bracket without manufacturing the base plate, and it is possible to avoid a rise in manufacturing cost of the engine mount bracket and a decrease in workability in assembling.
