As shown in FIG. 13, an instrument panel reinforcement R is provided on the vehicle rear side of the pedal device 10 as a vehicle body structural material. The instrument panel reinforce R is conventionally provided in a vehicle, and is the same as the instrument panel reinforce R described in the related art. The guide member 80 is fixed to the instrument panel reinforcement R by welding or the like.

The guide member 80 has a guide surface 80a facing the link lever 32 of the link mechanism 73 and facing downward in front of the vehicle and having a slightly curved shape. The guide surface 80a is in a state where the pedal bracket B is not moved to the driver side due to deformation of the vehicle body due to a vehicle collision or the like, that is, the link mechanism 7 is in a normal state of the vehicle.
3 is provided at a position not to interfere.

When the vehicle body is deformed due to, for example, a collision and the pedal bracket B is moved to the driver side substantially horizontally by the brake booster cylinder, the guide member 80 abuts on the guide surface 80a with the top surface of the distal end of the link lever 32. It is provided to make it. And the guide surface 80a
As the link lever 32 moves to the rear of the vehicle,
By guiding the distal end portion of the link lever 32 downward on the rear side of the vehicle, the link lever 32 is swung so that the distal end portion moves further downward around the support shaft 21. At this time, the link lever 32 rotates against the reaction force from the brake booster cylinder.

As a result, the guide member 80 operates the link mechanism 73 in the same manner as when the brake pedal 30 is operated in the normal state of the vehicle, and moves the brake pedal 30 moved rearward by the collision to the link plate 31. The pedal portion 30c is rotated so as to move away from the driver about the connection portion with the center.

Next, the operation of the present embodiment configured as described above will be described. When the motor 48 is rotated forward or backward, the screw body 51 rotates and the nut member 45 moves along the screw portion 63, and the link plate 22 swings as shown in FIGS. Then, the pedal holder 16

9 moves back and forth in a state where its posture does not change significantly.

When the support shaft 21 is rotated, FIG.
As shown in FIG. 11, the link plate 31 also swings. At this time, since the swing of the link lever 32 is regulated by the brake booster cylinder, the link plate 3
The connector 33 swings with the swing of 1. Then, the brake pedal 30 moves in the front-back direction. At this time, the brake pedal 30 moves back and forth in a state where its posture does not change significantly due to the action of the link mechanism 73.

When the rotation of the motor 48 is stopped, the nut member 45 stops at a certain position on the screw portion 63, the rotation of the support shaft 21 stops, and the swing of the link plates 22 and 31 is stopped. Stop. When the swing of the link plate 22 and the link lever 23 is stopped, the accelerator pedal 15 is held at the front-back position at that time. Further, when the swing of the link plate 31 and the link lever 32 is stopped, the brake pedal 30 is held at the front / rear position at that time. At this time, the accelerator pedal 15 and the brake pedal 30 are adjusted before and after the vehicle body is adjusted via the support shaft 21, the link plate 22, the nut member 45, the shaft 54, the motor support 47, the joint housing 49, and the motor bracket 53. Held in position respectively.

When the accelerator pedal 15 is operated with the front and rear positions of both pedals 15 and 30 adjusted, as shown by a two-dot chain line in FIG. 7 or FIG. The accelerator pedal 15 rotates from the stepping start position against the urging force of the torsion coil spring 17. At this time, the depression amount of the accelerator pedal 15 is detected by the accelerator opening sensor 18. As the depressing force applied to the accelerator pedal 15 is reduced, the accelerator pedal 15 returns to the depressing start position by the urging force of the torsion coil spring 17.

When the brake pedal 30 is operated with the front and rear positions of both pedals 15 and 30 adjusted, as shown in FIGS. 9 and 10 or FIGS. 11 and 12, the pedaling force applied by the brake operation is reduced. Accordingly, the brake pedal 30 rotates from the depression start position against the reaction force from the brake booster cylinder side. Then, the brake booster cylinder activates the brake device according to the stepping force, and braking according to the stepping force is applied to the vehicle. As the stepping force is reduced, the brake pedal 30 returns to the stepping start position due to the reaction force from the brake booster cylinder side.

For example, when the vehicle collides with the brake pedal 30 not being braked and the vehicle body is deformed and the pedal bracket B is moved to the driver side, as shown in FIG. The upper surface of the distal end portion contacts the guide surface 80a of the guide member 80. Then, as the pedal bracket B moves to the driver side, the link lever 3
2 is guided along the guide surface 80a, and the link lever 3 is moved so that the distal end 32a moves downward.
2 swings.

Then, the link mechanism 73 operates in the same manner as when the brake pedal 30 is braked, and rotates the brake pedal 30 about the connection with the link plate 31. As a result, the pedal section 30c moves forward of the vehicle with the pedal bracket B moved to the driver side.

According to the above-described embodiment, the following effects can be obtained. (1) Link mechanism 73 as in normal brake operation
By actuating the brake pedal 30, the brake pedal 30 is swung, and the pedal portion 30c is moved forward of the vehicle. For this reason, there is no need to provide the distal end portion 100a having rigidity enough to push down the pedal bracket 100 together with the brake booster cylinder unlike the related art, so that a large installation space is not required above the link mechanism 73. Therefore, it is difficult to reduce the installation property for the vehicle.

(2) The link mechanism 73 is operated by bringing the link lever 32 into contact with the guide surface 80a of the guide member 80 provided on the instrument panel reinforcement R. For this reason, it can be implemented with a simple structure without any moving parts. Further, in comparison with the conventional pedal device, there is no need to add new parts and assembly man-hours to the vehicle body. (Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. The second embodiment is different from the first embodiment only in that the pedal bracket B in the first embodiment is changed to the pedal bracket B1 and the support member 81 and the contact member 82 are provided instead of the guide member 80.

The support member 81 and the pedal bracket B1
When the pedal bracket B1 moves to the driver side substantially horizontally with the deformation of the vehicle body, the contact member 82 is swung so that the contact piece 82a moves further downward, and the upper surface of the link lever 32 is The contact piece 82a is brought into contact. Then, as the link lever 32 moves to the driver side, the contact piece 8
2a pushes down the link lever 32 further downward, and swings the link lever 32 about the support shaft 21.

As a result, the link mechanism 73 is operated in the same manner as when the brake pedal 30 is braked, and the brake pedal 30 moved to the driver side is moved to the pedal portion 30c centering on the connection portion with the link plate 31. Swing away from the driver.

In the present embodiment, when the pedal bracket B1 moves to the rear of the vehicle to swing the contact member 82,

However, this is merely an operation of rotating the contact member 82 to swing the link lever 32, and an operation of swinging the brake pedal 30 to move the pedal portion 30c forward of the vehicle is performed by the link mechanism 73. Done.

According to the present embodiment described in detail above, the same effect as (1) in the first embodiment can be obtained. Note that unlike the conventional pedal bracket 100, the pedal bracket B1 of the present embodiment does not need to push down the pedal bracket B1 together with the brake booster cylinder, so that it is not necessary to increase the rigidity of the distal end portion.

Next, an embodiment other than the above-described embodiment will be described. In the first embodiment, the guide member 80 may be a guide unit provided integrally with the instrument panel reinforcement R.

In the second embodiment, the support member 81
May be a support unit provided integrally with the instrument panel reinforcement R.
