Therefore, the vehicle part mounting structure of the present invention according to claim 1 is a vehicle part installed between a dash panel and a strut tower provided in front of the dash panel. In the mounting structure of
The bracket supports the vehicle component so that the vehicle component is located above the strut tower. In addition, the bracket includes a bracket bottom portion that connects the strut tower and the dash panel to support the lower surface of the vehicle component, and a bracket side portion that extends from the bracket bottom portion and supports the side surface of the vehicle component. Since the notch that opens forward is formed on the strut tower side of the bottom surface or the side surface of the bracket, the bracket securely supports the vehicle parts between the bracket bottom surface and the bracket side surface during normal vehicle traveling. On the other hand, when the vehicle collides in the front-rear direction, the bottom surface of the bracket is likely to be rolled up to near the end of the cutout.

According to a second aspect of the present invention, there is provided the structure for mounting a vehicle component according to the first aspect, wherein the bracket is installed such that the lower front portion of the vehicle component is located above the strut tower. The bottom part has a bent part that is bent at a substantially right angle toward the strut tower side, which allows the bracket to receive the load from the vehicle part as a compressive load during normal vehicle traveling. Since the bending load is applied to the bent portion when the vehicle collides in the front-rear direction, the front portion of the bracket bottom portion can be smoothly and surely turned.

FIG. 3 is a diagram for explaining the deformation of the bracket during a vehicle collision. 1 to 3, the same parts as those of the conventional vehicle part mounting structure described above are designated by the same reference numerals.

In the vehicle part mounting structure of this embodiment,
As shown in FIGS. 1 and 2A and 2B, a vehicle component 7 is installed between the dash panel 1 and a strut tower 3 provided in front of the dash panel 1. A bracket 9 that supports the vehicle component 7 is provided so that the vehicle component 7 is located above the strut tower 3. The vehicle component 7 is, for example, an ABS hydraulic unit (hereinafter, simply referred to as an ABS unit), and a case where the ABS unit is applied as the vehicle component 7 will be described below.

The bracket 9 connects the strut tower 3 and the dash panel 1 to support the bottom surface of the ABS unit 7 and the bracket bottom portion 9A and the bracket bottom portion 9A.
And a bracket side surface portion 9B that extends from the side and supports the side surface of the ABS unit 7, and the bracket 9 is integrally formed by the bracket bottom surface portion 9A and the bracket side surface portion 9B.

The rear side of the bracket bottom portion 9A is fixed by a bolt 10a to a projecting piece 1a projecting from the dash panel 1 toward the inside of the engine room. Also,
The front side of the bracket bottom portion 9A is fixed to the upper surface of the strut tower 3 with bolts 10b so that the lower front portion of the ABS unit 7 is located above the strut tower 3. Further, on the front side of the bracket bottom surface portion 9A,
A bent portion 12 that is bent at a substantially right angle is formed toward the strut tower 3 side, and a cutout portion 11A that is opened forward is formed on the strut tower 3 side. The bracket bottom surface portion 9A is fixed to the bottom surface portion of the ABS unit 7 with a bolt 10e.

An outer portion of the bracket side surface portion 9B outside the engine room is fixed to the front upper frame 4 by a bolt 10f. In addition, the inner portion of the bracket side surface portion 9B in the engine room is the bolt 10c and the bolt 1
0d is fixed to the side surface of the ABS unit 7, and a notch 11B is formed on the side of the strut tower 3 and opens forward.

The vehicle part mounting structure as the embodiment of the present invention is constructed as described above, and therefore has the following actions and effects. That is, as shown in FIG. 3 (a), the bracket 9 is located above the strut tower 3.
By supporting the ABS unit 7 so that the BS unit 7 is positioned, and forming notches 11A and 11B that open forward on the strut tower 3 side of the bracket bottom surface portion 9A and the bracket side surface portion 9B, a normal vehicle While traveling, the bracket 9 securely supports the ABS unit 7 by the bracket bottom surface portion 9A and the bracket side surface portion 9B, while the engine room collapses and the strut tower 3 moves in the direction of arrow A when the vehicle collides in the front-rear direction. In this case, as shown in FIG. 3B, the front portion of the bracket bottom surface portion 9A is rolled up to near the end of the cutout portion 11A, and the ABS unit 7 moves above the strut tower 3.

As a result, when the vehicle is traveling normally, the AB
While the S unit 7 can be reliably supported, the ABS unit 7 is prevented from being sandwiched between the strut tower 3 and the dash panel 1 when the vehicle collides in the front-rear direction and the engine room is crushed. As a result, a sufficient crash stroke at the time of a vehicle collision can be secured, and impact energy can be efficiently absorbed.

Further, since the front lower end of the ABS unit 7 is located above the strut tower 3 and the bent portion 12 is formed in the front portion of the bracket bottom portion 9A, the bracket 9 is used during normal vehicle traveling. , Bend 1
2, the load from the ABS unit 7 can be received as a compressive load, but when the engine room is crushed during a front-back collision of the vehicle, the bending portion 12 receives a bending load, so that the load is smoother and more reliable. In addition, the front portion of the bracket bottom surface portion 9A can be turned.

Therefore, when the vehicle is traveling normally, the durability of the bracket 9 can be improved and the ABS unit 7 can be supported more reliably, while the vehicle collides in the front-rear direction and the engine room is crushed. In addition, the ABS unit 7 can be more reliably prevented from being caught between the strut tower 3 and the dash panel 1, and a sufficient crash stroke at the time of a vehicle front-back collision can be secured.

Further, the conventional vehicle part mounting structure is composed of a plurality of brackets. However, in the vehicle part mounting structure of the present invention, since it is composed of only one bracket 9, complicated mounting work is required. It is not necessary and the manufacturing cost can be suppressed.

As described in detail above, according to the vehicle part mounting structure of the present invention as set forth in claim 1, the bracket securely secures the vehicle part by the bracket bottom surface portion and the bracket side surface portion during normal vehicle traveling. On the other hand, when the vehicle collides in the front-rear direction, the bottom part of the bracket is rolled up to the vicinity of the end of the notch and the vehicle parts easily move above the strut tower. Prevents getting caught between the dash panel,
A sufficient crash stroke can be secured and impact energy can be efficiently absorbed.

According to the vehicle part mounting structure of the present invention as defined in claim 2, since the bracket can receive the load from the vehicle part as a compressive load at the bending portion during normal vehicle traveling, it is durable. On the other hand, since the bending load is applied to the bent portion when the vehicle collides in the front-rear direction, the front portion of the bracket bottom portion can be more smoothly and surely turned. As a result, it is possible to more reliably prevent the vehicle component from being caught between the strut tower and the dash panel, and it is possible to secure a sufficient crash stroke.
