SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to an upper portion of a pedal arm having a stepped portion at a lower end rotatably supported by a vehicle body, and moving the stepped portion from a set position with respect to the vehicle body. In a pedal device for performing an operation relating to vehicle traveling by stepping on, the pedal arm is divided into upper and lower middle portions to form an upper portion rotatably supported by the vehicle body and a lower portion on a stepping portion side, wherein the upper The lower part is stepped on the lower part of the part and is rotatably connected in the front-rear direction. Between the upper part and the lower part, the rotation of the lower part with respect to the upper part from the set position in the stepping direction is prevented. Stopper that allows rotation to the upper part, and rotation in the anti-stepping direction against the upper part of the lower part is prevented up to the set load. Characterized in that a positioning means that.

[0008]

[Function] When the stepping portion of the pedal arm at the set position is depressed, the force is transmitted to the lower portion, the stopper, and the upper portion of the pedal arm, and the entire pedal arm rotates around the vehicle body, and the expected position from the set position is obtained. A depressing operation can be performed. When a load equal to or greater than the set load acts on the lower portion of the pedal arm in the counter-stepping direction, the lower portion can rotate in the counter-stepping direction with respect to the upper portion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below.

FIG. 1 is a perspective view showing an assembled state, for example, showing a clutch pedal 1 as an embodiment of a pedal device. FIG. 2 is an exploded perspective view of the clutch pedal 1, and the clutch pedal 1 is supported on the vehicle body side as shown in FIG. That is, the clutch pedal 1 is a pedal arm 5 having a stepped portion 3 at the lower end.
Is rotatably supported by a support pin 9 on a pedal bracket 7 on the vehicle body side. And although not shown,
As in FIG. 5, a return spring for urging the pedal arm 5 to the set position is provided, and a connecting rod connected 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 upper and lower intermediate portions, and has an upper portion 11 supported by the pedal bracket 7 and a lower portion 13 on the stepping portion 3 side.

The upper part 11 and the lower part 13 divided as described above are connected to the upper part 11 so as to be rotatable in the front-rear direction by stepping on the lower part 13. That is, as shown in FIG. 2, an upper hinge support portion 15 is provided at a lower end portion of the upper portion 11, and a first hinge support hole 17 is provided in the upper hinge support portion 15.
At the upper end of the lower portion 13, lower hinge support portions 19 located on both sides of the upper hinge support portion 15 are provided, and lower hinge support holes 21 are provided. Then, the upper hinge support hole 17 and the lower hinge support hole 21 are aligned so that the lower hinge support portion 19 is positioned on both sides of the upper hinge support portion 15, and the hinge pin 23 is fitted into the support holes 17, 21. The upper part 11 and the lower part 13 are rotatably connected.

A stopper 25 is provided between the upper portion 11 and the lower portion 13 that are connected in this manner, to prevent the lower portion 13 from rotating in the stepping direction from the set position of the upper portion 11. This stopper 25
Is formed by a part of the lower end of the upper portion 11, and a concave portion 27 is provided at the upper end of the lower portion 13 corresponding thereto, and the stopper 25 is formed by the above-mentioned connection between the upper portion 11 and the lower portion 13. And the pedal arm 5 is integrally formed as a whole.

Further, a sprig 29 is provided between the upper portion 11 and the lower portion 13 as positioning means for preventing rotation of the lower portion 13 in the counter-depressing direction with respect to the upper portion 11 with a set load. This spring 29
1 fits at the portion where the hinge pin 23 protrudes from the end of the lower hinge support portion 19 as shown in FIG. 1, and one arm 31 of the spring 29 engages with the spring support portion 33 of the upper portion 11 and the other The arm 35 is engaged with a spring support 37 of the lower part 13. Accordingly, the lower portion 13 is urged against the upper portion 11 in the stepping direction around the hinge pin 23 by the urging of the spring 29, and the concave portion 27 of the lower portion 13 comes into contact with the stopper 25 of the upper portion 11, whereby the pedal arm 5 is moved. The whole is positioned at the set position.

[0015] Therefore, as shown in FIG.
When the pedal is depressed as indicated by an arrow, the pedal arm 5 rotates integrally with the support pin 9 of the pedal bracket 7 in the depressing direction, and the clutch engagement / disengagement operation can be performed as an operation related to vehicle running. When the depression is released, the return arm (not shown) around the support pin 9 integrally returns the pedal arm 5 to the set position.

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 the arrow, so that 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 an 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 the clutch pedal 1 is not damaged at the same time. 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 rotation of the lower portion 13 in the counter-depressing direction with respect to the upper portion 11 is prevented by the biasing force of the spring 39 with a set load, so that the pedal is divided into two parts, the upper portion 11 and the lower portion 13. 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 the 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 the frictional force. It is also possible to configure so as not to rotate to the maximum. In addition, upper part 1
The shear pin is broken by the set load by interposing the shear pin between the rotating part of the first part and the lower part 13.
The lower portion 13 may be configured to be allowed to rotate 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 clear from the above, according to the structure 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 part due to the deformation is in the direction in which the lower part is depressed against the upper part. Since the rotation is released and the deformation is not suppressed, the impact energy can be sufficiently absorbed.
