The pedal arm 46 of the brake pedal 10
A rotary shaft portion 50 is provided at an upper end of the pedal bracket 30, and the rotary shaft portion 50 is supported by a pair of side plate portions 34 of the pedal bracket 30. When briefly touching an example of the configuration of the rotary shaft portion 50, a substantially cylindrical pedal boss is press-fitted into a through hole formed at the upper end portion of the pedal arm portion 46 and cylindrical end portions are formed at both ends of the pedal boss. After each of the bushes is fitted into the bush, and a cylindrical collar is inserted into both bushes, a mounting bolt 52 is inserted from the outside of one side plate portion 34 and a nut 54 is inserted from the outside of the other side plate portion 34. Are screwed together to form a rotating shaft portion 50.

A distal end of a push rod (operating rod) 56 projecting from the brake booster 24 and penetrating through the dash panel 16 is connected to an intermediate portion of the pedal arm 46 of the brake pedal 10.
Specifically, a clevis 58 having a substantially U-shaped cross section is attached to the tip of the push rod 56. Inside the clevis 58, a pedal arm portion 46 is disposed in an inserted state. A clevis pin 60 passes through both sides of the clevis 58 and the pedal arm portion 46, and a retaining ring, a β pin, etc. The push rod 56 and the pedal arm 46 are connected to be relatively rotatable by being prevented from being removed.

At the rear end side of the top wall portion of the top plate portion 36 of the pedal bracket 30, a sliding portion 36A that is gently inclined substantially below the vehicle with respect to the general surface of the top wall portion is provided. Is formed. Further, near the center of the top wall portion of the top plate portion 36, a narrow portion 62A having a narrow opening width and a wide portion 62B communicating with the narrow portion 62A and having a wide opening width are provided. An opening 62 is formed as a “separation unit”. The opening width of the narrow portion 62A is set so that the male screw portion 70A of the mounting bolt 70 to be described later can be inserted but the head 70B cannot be inserted, and the opening width of the wide portion 62B is set to the head 70B.
Are also set to dimensions that can be inserted.

Using the opening 62, the rear end side of the pedal bracket 30 is provided with the cowl inner panel 2 as follows.
2 are connected. That is, the cowl inner panel 2
A front portion (A portion) of a slide guide plate 64 as "guide means", which will be described in detail later, is fixed to the lower portion of the rear end 2 by spot welding. As the fixing means, welding other than spot welding, bolting, etc. can be used. The front of the slide guide plate 64 (A
Part), a bolt insertion hole 66 is formed at the center.
Correspondingly, a weld nut 68 is welded to the cowl inner panel 22 at a position coaxial with the bolt insertion hole 66. And, a narrow portion 62A of an opening 62 formed in the top plate portion 36 of the pedal bracket 30,
Bolt insertion hole 66 formed in slide guide plate 64 and weld nut 68 of cowl inner panel 22
When the mounting bolt 70 is screwed into the weld nut 68 from the lower side of the top plate portion 36 through the narrow portion 62A and the bolt insertion hole 66 in a state where the rear end of the pedal bracket 30 is The side is connected to the cowl inner panel 22.

Therefore, when the mounting bolt 70 is located at the narrow portion 62A, which is the mounting position (as shown in FIG. 5A), the rear end side of the pedal bracket 30 (the top plate portion 36). ) Maintains the state of being coupled to the cowl inner panel 22 via the slide guide plate 64. However, when the pedal bracket 30 is displaced relatively to the rear side of the cowl with respect to the cowl inner panel 22, the mounting bolt 70 is relatively moved. The rear end of the pedal bracket 30 is separated from the cowl inner panel 22 (see FIG. 5B).

Here, the above-described slide guide plate 64 has a top wall 6 that functions as a slide guide surface in shape.
4A and a pair of side wall portions 64B bent down from both side edges of the top wall portion 64A and serving to prevent the sliding portion 36A of the top plate portion 36 from coming off the track. Is formed.

The slide guide plate 64 is formed as a long member which is formed substantially long in the front-rear direction of the vehicle. More specifically, the slide guide plate 64 is fixed to the cowl inner panel 22 and is slightly inclined forward substantially toward the lower front side of the vehicle (part A).
An intermediate portion (portion B) curved from the front portion (portion A) with a predetermined radius of curvature, and a rear portion inclined rearward from the intermediate portion (portion B) substantially downward toward the rear of the vehicle. (C section). Accordingly, the slide guide plate 64 is formed in a substantially “H” shape in a side view.
The inclination angles of the front portion (A portion) and the rear portion (C portion) of the slide guide plate 64 and the radius of curvature of the intermediate portion (B portion), and more particularly, the length of the rear portion (C portion) are determined by the pedal bracket 30. Is determined by the relationship of the amount of rotational displacement on the rear end side with respect to the front end side.

Further, a rear portion (C portion) of the slide guide plate 64 is extended so as not to contact below the instrument panel reinforcement 72 which is disposed substantially rearward of the vehicle with respect to the dash panel 16. The instrument panel reinforcement 72 is a high-strength member arranged with the vehicle width direction as a longitudinal direction, and is also a member supporting the steering column via a steering support 74 welded to the instrument panel reinforcement 72. Also,
The rear portion (C portion) of the slide guide plate 64 is also disposed substantially apart from the steering support 74 in the vehicle width direction. In other words, the rear part (C part) of the slide guide plate 64 is the instrument panel reinforcement 72.
And the steering support 74 exists independently without welding.

Next, the operation and effect of this embodiment will be described. As shown in FIG. 1, when the brake is not operated, the brake pedal 10 is held at the initial position by the urging force of the return spring. When the occupant applies a pedaling force to the pedal pad 48 of the brake pedal 10 from this state, the brake pedal 10
The push rod 56 is swung about substantially forward of the vehicle, and the push rod 56 is pressed substantially forward of the vehicle. As a result, the occupant's treading force applied to the pedal pad 48 is transmitted to the brake booster 24 via the push rod 56 and is increased, and then converted into a hydraulic pressure by the master cylinder 26.

On the other hand, when an external force exceeding a predetermined value acts on the front portion of the vehicle, the load at that time may be input to the dash panel 16 via the master cylinder 26 and the brake booster 24. In this case, as shown in FIG. 2, the dash panel 16 is displaced substantially toward the vehicle rear side.

For this reason, a relative displacement occurs between the pedal bracket 30 and the cowl inner panel 22, and the position of the head 70 B of the mounting bolt 70 connecting the rear end of the pedal bracket 30 to the cowl inner panel 22 is changed. Opening 62
From the narrow portion 62A to the wide portion 62B. Thereby, the head 70B of the mounting bolt 70 is
2, the rear end side of the pedal bracket 30 and the cowl inner panel 22 are disconnected from each other.

Thereafter, the rear end side (specifically, the sliding portion 36A of the top plate portion 36) of the pedal bracket 30 detached from the cowl inner panel 22 is attached to the cowl inner panel 22 as shown in FIG. Along the top wall portion 64A of the fixed slide guide plate 64, the front portion (A
Part), the middle part (part B), and the rear part (part C). When the sliding portion 36A of the pedal bracket 30 slides on the top wall 64A of the slide guide plate 64, a pair of side wall portions is provided so that the sliding portion 36A does not separate from the top wall 64A of the slide guide plate 64. 64B
Regulated by

In the above-described sliding process, particularly when the sliding portion 36A of the pedal bracket 30 passes through the intermediate portion (B portion) of the slide guide plate 64, the pedal bracket 30
The pair of side plate portions 34 are subjected to a rotational force substantially downward of the vehicle, and the rigidity of the side plate portions 34 substantially in the front-rear direction of the vehicle is intentionally reduced by the opening 38. The rear end side of the cylinder 30 is rotationally displaced while being plastically deformed substantially toward the lower side of the vehicle and substantially toward the front side of the vehicle. The amount of this rotational displacement is such that the sliding portion 36A of the pedal bracket 30
Is further increased when sliding on the rear part (part C).

Since the brake pedal 10 is supported by the pedal bracket 30, the pedal pad 48 of the brake pedal 10 also rotates substantially forward of the vehicle as the rear end of the pedal bracket 30 is rotationally displaced as described above. Displaced. In other words, according to the present embodiment, the displacement of the pedal pad 48 of the brake pedal 10 when an external force equal to or more than a predetermined value acts on the front portion of the vehicle becomes desired, that is, the pedal pad of the brake pedal 10 48 can be controlled to be largely displaced substantially toward the front of the vehicle. As a result, the knee of the leg due to the inertial movement of the occupant when an external force equal to or more than the predetermined value acts from the front of the vehicle can be suppressed, and thus the occupant's knee can be moved away from the steering column. .

Further, in the present embodiment, the rear portion (C portion) of the slide guide plate 64 is extended so as not to contact substantially below the vehicle side of the instrument panel reinforcement 72 supporting the steering column. Rear (C part) instrument panel reinforcement 7
2 and the steering support 74 are independently provided without welding, so that when the rear end side of the detached pedal bracket 30 slides along the slide guide plate 64, the pedal Even if a pushing force is applied from the rear end side of the bracket 30 to the rear part (C part) of the slide guide plate 64, the slide guide plate 64
The rear part (C part) does not interfere with the instrument panel reinforcement 72, or even if the rear part (C part) of the slide guide plate 64 interferes with the instrument panel reinforcement 72, the interference is only slight. As a result, the pedal bracket 30 is moved through the rear portion (C portion) of the slide guide plate 64.
The load applied to the instrument panel reinforcement 72 and further to the steering column from the rear end side can be reduced or significantly reduced. In other words, according to the present embodiment, it is possible to prevent the pedal bracket 30 from directly affecting the instrument panel reinforcement 72 and further the steering column when an external force equal to or more than a predetermined value acts on the front portion of the vehicle. it can.

In addition, an arc welding operation is unnecessary compared to a structure in which the guide means corresponding to the slide guide plate 64 is arc welded to both the instrument panel reinforcement 72 and the steering support 74 and the strength is supplemented by a reinforcing member such as a reinforcing plate. And the number of parts can be reduced. Therefore, the displacement control structure of the brake pedal 10 can be simplified and the cost can be reduced.

In the present embodiment, the present invention is applied to a suspended main brake pedal. However, the present invention is not limited to this, and may be applied to a suspended clutch pedal or a depressed parking brake. The present invention is also applicable to a vehicle pedal such as a pedal.

In this embodiment, the front portion (A) of the slide guide plate 64 is welded to the cowl inner panel 22 in advance, and the front portion (A) of the slide guide plate 64 is welded.
The rear end side of the pedal bracket 30 is connected to the cowl inner panel 22 with the mounting bolts 70 and the weld nuts 68 in such a manner that the rear end of the pedal bracket 30 is held between the cowl inner panel 22 and the slide guide plate 64. Of the slide guide plate 64 may be adopted together with the pedal bracket 30 together with the mounting bolt 70 and the weld nut 68.
Is bent substantially upward of the vehicle and fixed to the rear end surface of the cowl inner panel 22, and the rear end side of the pedal bracket 30 is attached to the cowl inner panel 22 without sandwiching the front portion (A portion) of the slide guide plate 64. A configuration in which the attachment bolt 70 and the weld nut 68 are used for coupling may be adopted.

Further, in the present embodiment, the slide guide plate 64 is basically formed in a substantially "H" shape in side view with the longitudinal direction substantially in the vehicle front-rear direction. While extending the rear portion (C portion) of the instrument panel reinforcement 72 substantially below the vehicle,
It may be configured to bend substantially in the vehicle width direction. With this configuration, when an external force equal to or more than a predetermined value acts on the front portion of the vehicle, the pedal pad 48 of the brake pedal 10 can be displaced substantially in the front side of the vehicle and substantially in the vehicle width direction.

Further, in this embodiment, the top plate 36 of the pedal bracket 30 is provided so that the rear end of the pedal bracket 30 is detached from the cowl inner panel 22 when an external force equal to or more than a predetermined value acts on the front portion of the vehicle. Although the opening 62 is formed, the invention is not limited thereto, and any configuration is applicable as long as the rear end side of the pedal bracket 30 separates from the cowl inner panel 22 when an external force equal to or more than a predetermined value acts on the front portion of the vehicle. For example, various configurations can be applied, such as joining the top plate portion 36 of the pedal bracket 30 and the cowl inner panel 22 with a shear pin that shears when a load equal to or more than a predetermined value acts.
