DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a connecting structure for an accelerator rod and an accelerator pedal that swingably connects a shaft member and a plate member with a connecting pin.

[Prior Art] This kind of member connecting structure is applied to connecting an accelerator rod 10 and an accelerator pedal 12 of an automobile as shown in FIG. 5, for example.

Accelerator rod 10 and accelerator pedal 12 shown in FIG.
As shown in FIG. 6, a pair of bearing plate portions 14 and 16 are formed on the accelerator pedal 12 to connect the hinge pin 18 from the axial direction to the bearing plate portion 14, the torsion coil spring 20, the accelerator rod 10, and the bearing plate portion. A structure in which the accelerator pedal 12 and the accelerator rod 10 are swingably connected by the hinge pin 18 by sequentially passing through 16 and then attaching a retaining ring 22 to the hinge pin 18 as shown in FIG. 7 to prevent the hinge pin 18 from coming off. Is.

By the way, in the connection structure of the accelerator rod 10 and the accelerator pedal 12, as shown in FIG. 6, in order to make the hinge pin 18 penetrate the accelerator rod 10, as shown in FIG.
Since it is necessary to form a hole 24 for penetrating the pin, the outer diameter of the accelerator rod 10 cannot be set to be small, which hinders the weight reduction of the accelerator rod 10. Also, the accelerator rod 10
If the hole 24 for pin penetration of the accelerator rod 10 is set to be larger than the outer diameter of the hinge pin 18 in order to penetrate the hinge pin 18 in the
The backlash between 12 and the hinge pin 18 increases. If the hinge pin 18 is press-fitted into the hole 24 in order to eliminate this play, the workability of inserting the hinge pin 18 into the hole 24 is deteriorated, and the assembling property is significantly deteriorated. In addition, the number of parts to be assembled is large and the assembling property is poor.

Therefore, in order to improve these points, as shown in FIG. 8, there has been proposed a structure in which the accelerator rod 10 and the accelerator pedal 12 are assembled while the hinge pin 18 is fixed to the accelerator rod 10 by welding or the like ( JP-A-60-197435). In this structure, as shown in FIG. 8, the bearing hole 26 formed in one bearing plate portion 16 of the accelerator pedal 12 is a bottomed hole, and the bearing hole 28 formed in the other bearing plate portion 14 is It is a large-diameter through hole, and the hinge pin 18 is fixed to the accelerator rod 10 at the intermediate portion in the axial direction.
Both ends of the hinge pin 18 can be inserted into the bearing holes 26 and 28, and after the both ends of the hinge pin 18 are inserted into the bearing holes 26 and 28, the bush 30
Is fitted in the bearing hole 28 to connect the accelerator rod 10 and the accelerator pedal 12 as shown in FIG. In this connection structure, the hinge pin 18 is fixed to the accelerator rod 10 so that the accelerator rod 10 and the hinge pin 18 are
Since and are integrated, accelerator rod 10 and hinge pin
There is no play between 18 and. Further, it is not necessary to set a hole for penetrating the hinge pin 18 in the accelerator rod 10 as described above, and the outer diameter of the accelerator rod 10 can be set small. Further, since the hinge pin 18 is fixed to the accelerator rod 10 while being assembled, the number of parts to be assembled is small and the assemblability is good.

However, in the connection structure of the accelerator rod 10 and the accelerator pedal 12 described above, in order to insert the hinge pin 18 into the bearing holes 26, 28, as shown in FIG.
It is necessary to tilt the hinge pin 18 with respect to 12, and it is difficult to insert the hinge pin 18 into the bearing holes 26 and 28.

[Embodiment] FIGS. 1 to 4 show an embodiment of a connecting structure for an accelerator rod and an accelerator pedal according to the present invention. In this embodiment, it is applied to the connection between the accelerator rod 40 as a shaft member and the accelerator pedal 42 as a plate member.

As shown in FIG. 1, a hinge pin 44, which is a connecting pin, is fixed to the accelerator rod 40 so that it can be assembled with the accelerator pedal 42 integrally with the hinge pin 44. The hinge pin 44 has its axially intermediate portion fixed to the accelerator rod 40 by welding or the like so as to be orthogonal to the accelerator rod 40. The hinge pin 44 is a stepped pin whose one end has a large diameter portion 46, and a ring groove 48 is formed at the end opposite to the large diameter portion 46. A retaining ring 50, which is a retaining member, is fitted into the ring groove 48.

A torsion coil spring 52 is attached to the accelerator rod 40 at an axially intermediate portion of the hinge pin 44, and the accelerator rod 42 is assembled with the hinge pin 44 and the torsion coil spring 52 attached in advance.

A first bearing hole 54A having a small diameter is formed in the first bearing plate portion 54. The first bearing hole 54A has a hole diameter that is substantially the same as the outer diameter of the end of the hinge pin 44 on the ring groove 48 side, and
The size of the end of 44 on the ring groove 48 side is such that it can be inserted from the axial direction.

The second bearing plate portion 56 is formed with a large diameter second bearing hole 56A and a slit 56B communicating with the second bearing hole 56A. The second bearing hole 56A has a hole diameter of a large diameter portion 46 of the hinge pin 44.
The outer diameter of the hinge pin 44 is approximately the same as the outer diameter of the hinge pin 44, and the large diameter portion 46 of the hinge pin 44 can be inserted in the axial direction. The slit 56B has a width that allows the axial intermediate portion of the hinge pin 44 to pass therethrough, and the axial intermediate portion of the hinge pin 44 is provided with a second bearing hole from the radial direction.
Can be inserted into 56A.

Next, a procedure for assembling the accelerator rod 40 and the accelerator pedal 42 will be described.

First, as shown in FIG. 2, the slit 56B of the accelerator pedal 42 is made to correspond to the axially intermediate portion of the hinge pin 44, and the hinge pin 44 is passed through the slit 56B as shown in FIG.
The intermediate portion of the hinge pin 44 is inserted into the second bearing hole 56A, and then the hinge pin 44 is moved in the axial direction to move the large diameter portion 46 of the hinge pin 44.

When the hinge pin 44 is inserted into the first bearing hole 54A and the second bearing hole 56A, the accelerator rod 40 and the torsion coil spring 52 are interposed between the first and second bearing plate portions 54 and 56 and the ring. The groove 48 penetrates the first bearing hole 54A and is located outside the first bearing plate portion 54.

Then, the snap ring 50 is fitted into the ring groove 48.

When the retaining ring 50 is fitted in the ring groove 48, the retaining ring 50 sandwiches the first bearing plate portion 54 with the accelerator rod 40 as shown in FIG. 4 to prevent the hinge pin 44 from coming off in the axial direction. .

As a result, the accelerator rod 40 and the accelerator pedal 42 are swingably connected by the hinge pin 44.

Thus, in this embodiment, the accelerator pedal
The accelerator rod 40 and the accelerator pedal 42 can be easily assembled with the hinge pin 44 fixed to the accelerator rod 40 without tilting the hinge pin 44 with respect to 42.

Since the accelerator rod 40 and the accelerator pedal 42 are assembled while the hinge pin 44 is fixed to the accelerator rod 40, there is no play between the accelerator rod 40 and the hinge pin 44, and the number of parts to be assembled is small.

And a second bearing portion having a slit that can be inserted into the bearing hole of the connecting pin, the axial intermediate portion of the connecting pin is fixed to the shaft member, and the axial intermediate portion of the connecting pin is inserted into the second bearing hole. Then, the connecting pin is moved in the axial direction to insert the large diameter portion of the connecting pin into the second bearing hole and the end portion of the connecting pin on the side opposite to the large diameter portion to the first bearing hole. Since the shaft member and the plate member are connected to each other by attaching the retaining member for restricting the movement of the connection pin in the axial direction to the connection pin later, the shaft member and the plate member are fixed with the connection pin fixed to the shaft member. It is possible to easily assemble the above-mentioned products more easily than ever, and further, it is possible to shorten the axial length of the connecting pin, and further, it is possible to reduce the manufacturing cost.
