EXAMPLE An example of the present invention will be described below.

FIG. 1 shows, for example, a clutch pedal 1 as an embodiment of a pedal device, and is a perspective view of an assembled state. FIG. 2 is a perspective view of the clutch pedal 1 in an exploded state, and the clutch pedal 1 is supported on the vehicle body side as shown in FIG. That is, the clutch pedal 1 has a pedal arm 5 having a stepped portion 3 at its lower end.
The upper part of the is rotatably supported by the support bracket 9 on the pedal bracket 7 on the vehicle body side. And although not shown,
Similar to FIG. 5, a return spring for urging the pedal arm 5 to the set position is provided, and a connecting rod for connecting to the control rod is connected.

On the other hand, in the embodiment of the present invention, FIGS.
As described above, the pedal arm 5 is divided into the upper and lower middle portions, and the upper portion 11 that supports the pedal bracket 7 and the lower portion 13 on the stepping portion 3 side are configured.

The upper portion 11 and the lower portion 13, which are divided as described above, are joined to the upper portion 11 such that the lower portion 13 is depressed to rotate in the front-rear direction. That is, as shown in FIG. 2, the upper hinge support portion 15 is provided at the lower end of the upper portion 11, and the first hinge support hole 17 is provided in the upper hinge support portion 15.
Further, a lower hinge support portion 19 located on both sides of the upper hinge support portion 15 is provided at an upper end portion of the lower portion 13, and a lower hinge support hole 21 is provided therein. Then, the lower hinge support portion 19 is positioned on both sides of the upper hinge support portion 15 so that the upper hinge support hole 17 and the lower hinge support hole 21 are aligned with each other, and the hinge pin 23 is fitted into both the support holes 17, 21. The upper portion 11 and the lower portion 13 are rotatably connected.

A stopper 25 is provided between the upper portion 11 and the lower portion 13 thus connected to prevent rotation of the lower portion 13 relative to the upper portion 11 in the stepping direction from the set position. This stopper 25
Is a part of the lower end of the upper part 11, and a recess 27 is provided at the upper end of the lower part 13 corresponding to the upper part 11, and the stopper 25 is provided with the recess 27 by the above-mentioned coupling of the upper part 11 and the lower part 13. To form an integral pedal arm 5 as a whole.

Further, a sprig 29 is provided between the upper portion 11 and the lower portion 13 as a positioning means for preventing the lower portion 13 from rotating in a direction opposite to the depression direction with respect to the upper portion 11 by a set load. This spring 29
Fits as shown in FIG. 1 at the portion where the hinge pin 23 projects to the end of the lower hinge support portion 19, one arm 31 of this spring 29 engages with the spring support portion 33 of the upper portion 11, and the other The arm 35 is engaged with the spring support portion 37 of the lower portion 13. Therefore, the lower portion 13 is biased toward the upper portion 11 in the stepping direction around the hinge pin 23 by the bias of the spring 29, and the recess 27 of the lower portion 13 contacts the stopper 25 of the upper portion 11, whereby the pedal arm 5 moves. It will be positioned at the set position as a whole.

Therefore, as shown in FIG.
When the pedal is depressed as indicated by the arrow, the pedal arm 5 rotates integrally around the support pin 9 of the pedal bracket 7 in the stepping direction, and the clutch engagement / disengagement operation can be performed as an operation related to vehicle running. Further, when the depression is released, the pedal arm 5 is integrally returned to the set position by a return spring (not shown) around the support pin 9.

Even if the dash panel lower 41 is deformed as shown in FIG. 4 due to a vehicle collision, the lower portion 13 of the pedal arm 5 escapes as shown by an arrow, and therefore the deformation is not suppressed.

That is, when the lower portion 13 of the clutch pedal 1 is pushed by the deforming portion 43 as shown by the arrow in FIG. 4, the lower portion 13 rotates about the hinge pin 23,
The load acting on the pedal arm 5 is easily released, and at the same time, the clutch pedal 1 is not damaged. Therefore, the impact energy can be absorbed without suppressing the deformation of the deformation portion 43 of the dash panel lower 41.

In the normal state, the biasing of the spring 39 prevents the lower part 13 from rotating in the direction opposite to the stepping-in direction with respect to the upper part 11 by the set load, so that the upper part 11 and the lower part 13 are divided into two pedals. Arm 5
There is no rattling of itself.

The present invention is not limited to the above embodiment. For example, as the positioning means, a predetermined frictional force is applied between rotating parts between the upper part 11 and the lower part 13 (for example, between the hinge pin 23 and the support holes 17 and 21), and a predetermined set load is applied by this frictional force. It is also possible to configure so as not to rotate. Also, the upper part 1
By interposing a shear pin between the rotating part of 1 and the lower part 13, the shear pin is destroyed by the set load,
It is also possible to allow rotation of the lower portion 13 with respect to the upper portion 11.

Further, the present invention can be applied not only to the clutch pedal but also to a brake pedal, an accelerator pedal and the like.

[0021]

As is apparent from the above, according to the configuration of the present invention, even if the vehicle body panel is deformed due to a vehicle collision or the like, the load acting on the lower portion due to the deformation is in the anti-stepping direction of the lower portion with respect to the upper portion. The impact energy can be sufficiently absorbed because it is released by the rotation to the side and the deformation is not suppressed.
