In a vehicle pedal in which a pedal body is rotatably supported by a support plate provided on a floor panel and a covering member is provided on the pedal body, a rear part of the pedal body is provided at a rear part of the covering part. An automobile pedal has been proposed in which a surrounding bellows structure is provided, and the end of the bellows structure is fixed to a support plate or a floor panel, but such a technique is limited to the structure of an organ type brake pedal. It could not be applied to the structure of the brake pedal shown in FIG.

Japanese Utility Model Publication No. 60-16976 discloses an accelerator pedal and a heel pad for a brake pedal which are provided with a common heel pad on a floor portion in front of an organ type brake pedal and an accelerator pedal. However, such a device did not solve the above problem.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a vehicle brake pedal that prevents a poor return of a brake pedal due to pinching of pebbles or the like.

[Means for solving the problem]

In order to achieve such an object, a vehicle brake pedal according to the present invention has a roller at a lower end, a substantially horizontally arranged push rod for braking operation is connected, and a push rod is provided for braking operation. A first pedal arm for pushing a rod in a substantially horizontal direction and a second pedal arm having a pedal body at a lower end are rotatably mounted on pedal brackets provided inside a front panel, respectively, and the rollers are mounted on a driver. A spring elastically supporting the seat side is stretched between the first pedal arm and the pedal bracket, and the roller is rollably contacted with a back surface near a lower end of the second pedal arm. The second pedal arm is supported by one pedal arm.

[Operation] According to the present invention, when the pedal body is depressed, the first pedal arm moves forward through the roller that rolls against the rear side surface of the second pedal arm, and the brake is actuated. .

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the same elements as those in the above-described conventional example are denoted by the same reference numerals, and a description of their structures is omitted.

1 and 2 show an embodiment of the present invention. In the drawings, reference numeral 15 denotes a first pedal arm, and the first pedal arm 15 is a lower side portion like the pedal arm 1 of the conventional example.
The roller 3 is attached to the front panel 15a, and the vicinity of the upper end 15b is rotatably mounted on a pivot shaft 15c provided on the pedal bracket 7 provided inside the front panel 5, and furthermore the upper end 1b is provided.
A spring 14 for urging the roller 3 in the direction of arrow A is provided between 5b and a spring engaging portion 7a provided integrally with the pedal bracket 7.

Reference numeral 16 denotes a second U-shaped cross-section having a certain length.
In the pedal arm, the second pedal arm 16 has its upper end 16a pivotally attached to a pivot shaft 16c provided on the lower front side of the pedal bracket 7 as compared with the upper end 15b of the first pedal arm 15. A substantially rectangular pedal body 17 is attached to the lower end 16b. Then, as shown in FIG. 2, the first pedal arm 15 is attached to the rear side surface 16d of the second pedal arm 16.
The roller 3 is rollably contacted with the first pedal arm 15 and the second pedal arm 16 is supported, while the spring force of the spring 14 urges the pedal body 17 toward the driver seat. A space is formed between the pedal body 17 and the floor panel 11.

When the pedal body 17 is depressed, the first pedal arm 15 moves in the direction of arrow B against the spring force of the spring 14 while the roller 3 rolls on the rear side surface 16d of the second pedal arm 16. The push rod 13 is moved in the direction of arrow C to activate the brake.

When the foot is released from the pedal body 17, the first pedal arm
The first pedal arm 15 moves in the direction of arrow A while the roller 3 rolls due to the spring force of the spring 14 stretched between the spring engaging portion 7a provided integrally with the pedal bracket 7 and the first pedal arm 15. The two-pedal arm 16 is returned, and the pedal body 17 is returned to the driver seat side.

Since the present embodiment is configured as described above, the pedal body 17 attached to the second pedal arm 16 as shown in FIG.
When the pedal 3 is depressed, the roller 3 in contact with the rear side surface 16d of the second pedal arm 16 rolls, and the first pedal arm 15
And the push rod 13 connected thereto is moved in the direction of arrow C to operate the brake, and
When the foot is released, the spring 14 causes the pedal body 17 to return to the driver seat side.

As described above, in the present embodiment, the pedal body is attached to the pedal arm, and the pedal arm is pivotally mounted on the pedal bracket to form a space between the pedal body and the floor panel. For example, the return of the brake pedal due to pinching of pebbles or the like as in the related art is eliminated, and the brake is not dragged, so that the braking failure due to seizure of the lining can be prevented.

Further, the labor for making a hole in a floor mat, a carpet, or the like can be omitted, and the pedaling force at the time of maximum stepping can be reduced as compared with the related art.

[Effect of the invention]

As described above, the present invention relates to a first pedal arm which has a roller at a lower end thereof and which is connected to a substantially horizontally arranged push rod for brake operation and which pushes the push rod substantially horizontally when the brake is operated. A second pedal arm having a pedal body at a lower end is rotatably mounted on a pedal bracket provided on the inside of the front panel, and a spring for elastically supporting the roller toward the driver seat is provided on the second arm. The second pedal arm is supported by the first pedal arm by stretching the roller between the one pedal arm and the pedal bracket, rolling the roller against the rear surface near the lower end of the second pedal arm. Because of this, a space is formed between the pedal body and the floor panel. Return with failure is eliminated dull, there is no brake pull fishing, brake failure and thus be prevented by with lining baking.

Further, the labor for making a hole in a floor mat, a carpet, or the like can be omitted, and further, the treading force at the time of maximum stepping can be reduced as compared with the related art.
