1 is a rear floor panel forming a rear floor of an automobile, in which side members 2 having a U-shaped cross section extending in the front-rear direction are fixed to the lower surface of the rear floor panel 1 and to both sides in the vehicle width direction. At the same time, a storage recess 10 for the spare tire 3 is formed in the center of the rear floor panel 1.

As is well known, the spare tire 3 has a bolt 32 inserted through a wheel 31 assembled to the spare tire 3, and an insertion end of the bolt 32 is attached to a lower surface of a bottom wall 11 in the accommodation recess 10. It is stored in the accommodating recess 10 by being screwed into the nut 33 that is fixed to the.

Reference numeral 31 in the drawing denotes a wheel assembled to the spare tire 3.

In the embodiment shown in the drawings, however, the actuator 4 of the antilock brake system, which is an accessory of the automobile, is mounted below the rear floor panel 1 as described below.

That is, the mounting bracket 5 extending in the vehicle width direction is fixed to the lower surface of the actuator 4 through the bolt 50, and one end side in the length direction of the mounting bracket 5 is fixed to the lower wall 21 of the side member 2. The other end is fixed to the bottom wall 11 of the accommodation recess 10 in the floor panel 1 and to a position facing the spare tire 3 accommodated in the accommodation recess 10 via bolts 6a and 6b, respectively. Therefore, specifically, a pair of front and rear cutout grooves 51a are formed at one end in the length direction of the mounting bracket 5, and a cylindrical rubber mount 7a is fitted into the cutout grooves 51, and By inserting the bolt 6a into the rubber mount 7a and screwing the insertion end portion into the nut 23 fixed to the upper surface of the lower wall 21 through the through hole 22 formed in the lower wall 21, One end side in the length direction of the mounting bracket 5 is fixed to the lower wall 21 of the side member 2.

Further, a pair of front and rear cutout grooves 51b are formed at the other end of the mounting bracket 5 in the lengthwise direction, and the cylindrical rubber mount 7b is fitted into the cutout grooves 51b, while a narrow width extending in the frontward and rearward direction is formed. The stiffener 8 is separately formed, and the through holes 81 are formed at both ends of the stiffener 8 in the lengthwise direction, and the screw shaft portion 61 of the bolt 6b is inserted into the through hole 81 to fix the bolt 6b. The head 62 is fixed to the upper surface of the stiffener 8 by welding.

On the other hand, a pair of front and rear insertion holes 12 corresponding to the through holes 81 formed in the stiffener 8 are formed in a portion of the bottom wall 11 facing the spare tire 3, while the lower surface of the stiffener 8 is formed. A ring-shaped adhesive 9 having a sealing property, which is formed of a thick double-sided tape formed in a ring shape, is attached to the peripheral portion of the through hole 81 in FIG.

As the adhesive 9, a butyl rubber sheet formed in a ring shape having both an adhesive function and a sealing function may be used.

Then, the screw shaft portion 61 of the bolt 6 b assembled to the stiffener 8 is inserted into the insertion hole 12, and the insertion end portion is projected below the bottom wall 11, and the stiffener 8 is provided. The adhesive material 9 attached to the lower surface of the bottom wall 11 is aligned with the peripheral edge of the insertion hole 12 on the upper surface of the bottom wall 11, and the bolt material 6 is attached to the bottom wall 11 by the adhesive material 9 together with the stiffener 8. After being fixed to the upper surface, the rubber mount 7b assembled to the other end portion in the length direction of the mounting bracket 5 is inserted into the screw shaft portion 61 of the bolt 6b, and is attached to the free end portion of the screw shaft portion 61. By screwing the nut 63, the other lengthwise end of the mounting bracket 5 is fixed to the bottom wall 11 via the bolt 6b.

When the rubber mount 7b assembled to the other end of the mounting bracket 5 in the lengthwise direction is inserted into the screw shaft portion 61 of the bolt 6b protruding downward from the bottom wall 11, Even if the rubber mount 7b accidentally pushes the bolt 6b upward, the bolt 6b is fixed to the bottom wall 11 by the adhesive 9 via the stiffener 8. The screw shaft portion 61 does not escape to the passenger compartment side. Therefore, when assembling the mounting bracket 5 to the bolt 6b, it is not necessary to hold the bolt 6b from the passenger compartment side, and the assembling work of the mounting bracket 5 to the bolt 6b is simple and easy. It can be done.

Moreover, since the periphery of the insertion hole 12 formed in the bottom wall 11 is sealed by the adhesive material 9, it is possible to reliably prevent water or the like from entering the vehicle compartment through the insertion hole 12. ..

Further, in the above embodiment, since one end side of the mounting bracket 5 provided on the actuator 4 is fixed to the side member 2 having rigidity, the operating vibration of the actuator 4 causes the mounting bracket 5 to move. Even if it is transmitted to the side member 2 through the side member 2, it is not propagated from the side member 2 to the floor panel 1, and the other end of the mounting bracket 5 is accommodated in the floor panel 1. Since it is fixed to the bottom wall 11 of the recess 10 at a position facing the spare tire 3, the operating vibration of the actuator 4 is transmitted to the bottom wall 11 via the mounting bracket 5, Even if the wall 11 resonates, the spare tire 3 to which the wheel 31 is attached functions as a so-called mass damper and is mounted on the bottom wall 11. The spare tire 3 plays the role of a spring member, and the wheel 31 assembled to the spare tire 3 plays the role of a weight, so that the so-called dynamic damper acts and the vibration transmitted to the bottom wall 11 is efficiently generated. It is well dampened.

Further, in the above embodiment, since the mounting bracket 5 is bolted to the side member 2 and the bottom wall 11 via the rubber mounts 7a and 7b, the mounting bracket 5 is assembled to the mounting bracket 5. The actuator 4 is elastically supported on the body, that is, the floor panel 1 to the side member 2 via the rubber mounts 7a and 7b. Therefore, the floor panel 1 and the side member 2 are used for high-speed running of a vehicle, for example. When vibrating due to the accompanying shake phenomenon, the actuator 4 and the rubber mounts 7a and 7b operate as a dynamic damper, and the vibrations of the floor panel 1 and the side members 2 are efficiently damped.

In the above embodiments, the actuator 4 of the anti-lock brake system is attached to the lower surface of the floor panel 1 as an accessory of the automobile, but the present invention is not limited to this, and other accessories. It can also be applied to mounting.
