Abstract

A brake pedal device includes a pedal bracket, an operation pedal, an intermediate lever, and a coupling link. The pedal bracket includes a first side plate member and a second side plate member secured to a dash panel and arranged at interval in a vehicle width direction, and is fastened and secured with respect to a vehicle body side bracket located on a vehicle rear side by a nut and a bolt at one location. The first side plate member and the second side plate member include a deformation allowing part and a deformation allowing part between a first support shaft located on a rearward side among the first support shaft and a second support shaft, and an attachment/securing part and an attachment/securing part.

First claim

What is claimed is:

1. A vehicle operation pedal device comprising:
a pedal bracket secured to a dash panel on a vehicle front side;
an operation pedal that is pivotally arranged by a first support shaft of the pedal bracket, and that includes a depressing part used for a depressing operation toward the vehicle front side;
an intermediate lever that is pivotally supported around a second support shaft arranged parallel to the first support shaft with respect to the pedal bracket, and that displaces a predetermined output member toward the vehicle front side by pivoting in an output direction with the second support shaft as a center; and
a coupling link that couples the operation pedal and the intermediate lever, and that pivots the intermediate lever in the output direction in cooperation with the depressing operation on the operation pedal; wherein
the pedal bracket includes a pair of side plates secured to the dash panel and arranged at interval in a vehicle width direction, and is fastened and secured with respect to a vehicle body side member located on a vehicle rear side than the dash panel at one location; and
the pair of side plates including a deformation allowing part that is a lower rigidity than other portions of the side plate, wherein the deformation allowing part is formed between an attachment/securing part where the pedal bracket is fastened and secured with respect to the vehicle body side member and the support shaft located on the vehicle rear side among the first support shaft and the second support shaft.

2. The vehicle operation pedal device according to claim 1 , wherein
the pair of side plates include,
a flange part that is formed along an end edge extending in a front and rear direction of the vehicle and that projects out in a direction of intersecting a plate surface of the side plate, and
a cutout part formed by cutting out a portion adjacent to the flange part among the end edge of the side plate extending along the front and rear direction of the vehicle; and

the deformation allowing part is configured to include a portion where the flange part and the cutout part are adjacent to each other.

3. The vehicle operation pedal device according to claim 1 , wherein
the attachment/securing part includes,
a fastening part used for fastening and securing of the pedal bracket with respect to the vehicle body side member, and
a weak part that is located on both sides in the vehicle width direction with respect to the fastening part, and that is a lower rigidity than other portions in the attachment/securing part.

4. The vehicle operation pedal device according to claim 2 , wherein
the attachment/securing part includes,
a fastening part used for fastening and securing of the pedal bracket with respect to the vehicle body side member, and
a weak part that is located on both sides in the vehicle width direction with respect to the fastening part, and that is a lower rigidity than other portions in the attachment/securing part.

5. The vehicle operation pedal device according to claim 1 , wherein the pedal bracket is configured by jointly fastening the attachment/securing part formed by fold processing a vehicle rearward side of one of the pair of side plates, and the attachment/securing part formed by fold processing a vehicle rearward side of the other one of the pair of side plates with respect to the vehicle body side member.

6. The vehicle operation pedal device according to claim 2 , wherein the pedal bracket is configured by jointly fastening the attachment/securing part formed by fold processing a vehicle rearward side of one of the pair of side plates, and the attachment/securing part formed by fold processing a vehicle rearward side of the other one of the pair of side plates with respect to the vehicle body side member.

7. The vehicle operation pedal device according to claim 3 , wherein the pedal bracket is configured by jointly fastening the attachment/securing part formed by fold processing a vehicle rearward side of one of the pair of side plates, and the attachment/securing part formed by fold processing a vehicle rearward side of the other one of the pair of side plates with respect to the vehicle body side member.

8. The vehicle operation pedal device according to claim 4 , wherein the pedal bracket is configured by jointly fastening the attachment/securing part formed by fold processing a vehicle rearward side of one of the pair of side plates, and the attachment/securing part formed by fold processing a vehicle rearward side of the other one of the pair of side plates with respect to the vehicle body side member.
