[Problems to be solved by the device]

What has been described in the prior art is that when the insulator and the insulator toe board are misaligned, the insulator may be caught in the tightening portion of the pedal box, resulting in improper tightening and loosening. There is a gap between the insulators. However, the provision of this gap causes a problem that noise in the engine room enters the interior through the gap.

The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide a booster device and a pedal box mounting structure for improving soundproofing performance and preventing tightening failure. Is what you are trying to do.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the mounting structure of the booster and the pedal box in the present invention is a booster in which an insulator is interposed between the toe board and the indoor toe board, and is arranged on the toe board from the engine room side. In the structure in which the bolt is positioned through the toe board in the opening portion of the insulator and the insulator toe board, and the pedal box is attached to the bolt from the indoor side through the spacer, the plurality of spacers are welded toward the toe board. An outer frame provided on the outer periphery of the substrate toward the toe board, a flange provided on the outer periphery of the outer frame and fixed to the toe board, and a penetrating portion which is opened in the center of the substrate and allows an operation rod to be inserted therethrough. Toeboard with the bracket facing the booster Attached, the opening portion of the insulator and the opening portion of the insulator toe board are made to correspond to the outer peripheral shape of the bracket, and the inner periphery of the opening of the insulator is in contact with the outer peripheral surface of the outer frame of the bracket, and the opening portion of the insulator toe board is Arrange the base plate of the bracket to arrange the insulator toe board and the base plate on substantially the same plane, and fasten the pedal box to the bolt of the booster passing through the spacer of the bracket and the bolt hole of the base plate with a nut, The pedal box is attached to a bracket, and the inside of the bracket is filled with a heat-foamable insulator.

[Operation] In the present invention, the pedal box is fastened to the bolt of the booster that passes through the spacer of the bracket and the board, and the pedal box is joined to the board of the bracket.
The insulator toe board is located around the base plate of the bracket so as to be flush with the base plate, and the insulator is in contact with the outer frame of the bracket, so that the insulator and the insulator toe board are prevented from being caught when the pedal box is mounted. And
There is no fear of defective tightening. Also, since the insulator contacts the outer periphery of the bracket and the inside of the bracket is filled with the heat-foamable insulator, the gap around the conventional spacer is eliminated and the noise from the engine room is prevented from entering. Become.

〔Example〕

Examples will be described with reference to the drawings. 1 to 2
In the figure, a toe board 2 for separating the engine room A and the room B from the cowl panel 1 and an insulator toe board 5 on the room B side are arranged, and the toe board 2 and the insulator toe board 5 are sandwiched in the engine room A. A pedal box 8 is arranged in the room B of the booster 7.

Further, a recess is provided in the portion of the toe board 2 where the booster 7 is arranged.
21 are formed.

The bracket 3 is arranged in the recess 21, and
The bracket 3 is provided with a cylindrical penetrating portion 31 through which the operating rod 10 is inserted, substantially at the center of the substrate 32.
A plurality of spacers 4 through which bolts 11 that connect the booster 7 and the pedal box 8 are inserted upright and welded around 31.

Further, an outer frame 33 is provided on the outer periphery of the substrate 32 and is formed in a box shape with the penetrating portion 31 and the spacer 4 arrangement portion being open,
A flange 34 is provided on the outer periphery of the outer frame 33. further,
Inside the bracket 3 is a heat-foaming type insulator 61.
Are filled without any gaps.

A brake pedal 9 that rotates about a shaft 91 is attached to the end of the operating rod 10. Further, an insulator 6 is arranged between the toe board 2 and the insulator toe board 5 without a gap. Then, as shown in FIG. 1, each of the insulator 6 and the insulator toe board 5 is provided with an opening portion corresponding to the outer peripheral shape of the bracket 3, and the bracket 3 is fitted into the opening portion. In this way, the insulator 6 and the insulator toe board 5 are attached, the inner periphery of the opening portion of the insulator 6 contacts the outer frame outer peripheral surface of the bracket 3, and the base plate 32 of the bracket 3 is positioned in the opening portion of the insulator toe board 5. Board 32 and insulator toe board 5 are provided so as to be substantially flush with each other. In this way, since the respective opening portions of the insulator 6 and the insulator toe board 5 correspond to the shape of the bracket 3,
The insulator 6 and the insulator toe board 5 are provided with a function of preventing a positional deviation from occurring when they are attached.

Further, as shown in the figure, the bolt 11 of the booster 7 arranged on the engine room side passes through the bolt holes provided in the spacer 4 and the base plate 32 of the bracket 3, and the operation rod 10 is inserted into the penetrating portion 31. , The pedal box 8 is placed on the base plate 32 of the bracket 3, and the bolt 11 is fastened by tightening the bolt 11 from the inside of the pedal box 8 with a nut, whereby the pedal box 8 is attached.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

By arranging the insulator between the toe board and the toe board and the bracket without any gap,
It is possible to efficiently prevent noise from entering the engine room.

Further, since the insulator toe board is positionally controlled by the shape of the bracket, the insulator toe board is not displaced, and the tightening failure of the pedal box tightening portion can be prevented. Further, since the bracket is arranged at the pedal box position, the structure becomes a multiple structure to improve the rigidity and the operation feeling when the brake pedal is depressed.
