2. Description of the Related Art Conventionally, there is Japanese Utility Model Laid-Open No. 63-152922 as a typical example which discloses this type of assembly structure. Specifically, as shown in FIG. 5, a steering gear input shaft 2 protruding from a steering gear housing 1 accommodating a steering gear (not shown),
A structure for assembling with a joint yoke 3 provided at a lower end portion of a steering shaft (not shown), wherein a male spline 2a is formed on the steering gear input shaft 2 in an axial direction of an outer peripheral surface and a direction orthogonal to an axis of the outer peripheral surface. Is formed with a bolt engaging groove 5 having a semicircular cross section, a female spline 4a is formed on the inner peripheral surface of the insertion hole 4 of the steering gear input shaft 2 in the joint yoke 3, and the bolt engaging groove is formed. Bolt holes 6 are opened at positions corresponding to the mating grooves 5. Then, one end of the joint yoke 3 is fixed in a state of being engaged with the end edge 3a of the joint yoke 3, and the other end of the joint yoke 3 is arranged in the radial direction passing through the center of the bolt hole 6 to prevent misassembly. A spring 7 is provided.

In such an assembling structure, when the joint yoke 3 is assembled to the steering gear input shaft 2, the bolt engagement groove 5 and the bolt hole 6 are aligned, that is, the steering gear input shaft 2 is properly arranged. If both are splined to each other and splined together, the wrong assembly prevention spring 7 is pushed by the end of the steering gear input shaft 2 and elastically deforms to a position where it comes off the bolt hole 6.
The joint yoke 3 can be assembled to the steering gear input shaft 2 by tightening bolts (not shown). On the other hand, when the bolt engagement groove 5 and the bolt hole 6 do not match, that is, when the steering gear input shaft 2 does not reach the proper position, the misassembly preventing spring 7 causes the steering gear input shaft 2 to end. When the steering gear input shaft is not pushed or is pushed, it is not elastically deformed up to the position where it is removed from the bolt hole 6 and remains in the approximate center of the bolt hole 6, which prevents the bolt from being inserted. It is said that the joint yoke 3 cannot be assembled to the No. 2 by tightening bolts, so that incorrect assembly is prevented.

However, the above-mentioned conventional assembly structure has the following inconveniences.
That is, in the assembling work of the assembling structure, it is difficult to attach the erroneous assembly preventing spring 7 to the joint yoke 3, so that the workability of the assembling work is deteriorated, and the attaching state of the erroneous assembling preventing spring 7 is confirmed. The man-hour was increasing. Also, the mis-assembly prevention spring 7 is connected to the joint yoke 3
Since it is fixed only in the state of being engaged with the edge 3a of
When the steering gear input shaft 2 is inserted, there is a possibility that one end of the misalignment prevention spring 7 itself may be disengaged from the end edge 3a due to the elastic deformation force of the misassembly prevention spring 7.

Next, when the joint yoke 12 is assembled to the steering gear input shaft 11, when the bolt engagement groove 16 and the bolt hole 22 are aligned, that is, the steering gear input shaft 11 is pushed to an appropriate position. 2 (see FIG. 2), the connecting portion between the first bending portion 27 and the second bending portion 28 of the misassembly preventing member 13 is pushed by the end portion of the steering gear input shaft 11, and one end of the fixing portion 26 is pressed. The joint yoke 12 can be assembled to the steering gear input shaft 11 by tightening the bolt, because the side yoke 26a is deformed to a position where the side 26a is disengaged from the bolt hole 22. At this time, the misassembly preventing member 13 is firmly engaged with the end edges A 1 and A 2 of the outer surface A of the joint yoke 12, so that the insertion preventing portion 27 due to the insertion of the steering gear input shaft 11 is prevented. Deformation of joint yoke 12
It does not come off. That is, when the steering gear input shaft 11 is inserted, the insertion preventing portion 25 of the misassembly preventing member 13 is deformed to a position where it is disengaged from the bolt hole 22 with the one end side 26a of the fixing portion 26 as a fulcrum.
6 tries to float outward from the outer surface A of the joint yoke 12. However, in the fixing portion 26, both ends 26a and 26b formed in a hook shape have the edges A 2 of the outer surface A.
And A 1 are firmly engaged with each other, the fixing portion 26 holds the joint yoke 12 even when the insertion preventing portion 25 is deformed.
It does not come off.

As described above, according to the assembling structure 10 of the present invention, the incorrect assembling preventing member 13 is attached in a state of being engaged with the two end edges A 1 and A 2 of the outer surface A of the joint yoke. Occasionally, there is no misalignment of positions, and the number of man-hours for checking the mounting state is reduced, improving workability.
The misassembly preventing member 13 is the joint yoke 1
Since the end edges A 1 and A 2 of the outer surface A of 2 are firmly engaged with each other, the insertion preventing portion 27 is not deformed by the insertion of the steering gear input shaft 11 so as not to come off from the joint yoke 12.

If the wrong assembly preventing member 13 is formed of a wire, for example, the rigidity in the inserting direction of the bolt is low. Therefore, if the bolt is inserted with an excessive force, the incorrect assembly preventing member 13 is deformed. However, in this embodiment, since the erroneous assembly preventing member 13 is formed of a plate material, the rigidity in the insertion direction of the bolt is improved and erroneous assembly can be prevented more reliably. You can Further, in the present embodiment, the case where the assembly structure is applied to the steering joint yoke structure of the vehicle has been described, but it is also possible to apply to other than this.

As is apparent from the above description, according to the assembling structure of the present invention, the misassembly preventing member is attached in a state of being engaged with the two end edges of the outer surface of the joint yoke. There is no misalignment or the like, and the number of man-hours for confirming the attachment state can be reduced, which improves workability. Further, since the incorrect assembly preventing member is firmly engaged with the two end edges of the outer surface of the joint yoke, the insertion preventing portion is not deformed due to the insertion of the shaft, and the incorrect assembly preventing member does not come off from the joint yoke. There is an effect that it can be realized.

1. A joint yoke having a hollow interior,
A shaft in which a shaft insertion hole connected to the hollow portion and a bolt hole penetrating in a direction orthogonal to the shaft insertion hole are formed, while a bolt engagement groove is formed on the outer surface along the circumferential direction and in alignment with the bolt hole. And a bolt that can be inserted into the bolt hole, insert the shaft into the shaft insertion hole to match the bolt hole with a bolt engagement groove, and then insert the bolt into the bolt hole In an assembling structure for assembling a joint yoke and a shaft, an insertion preventing portion that is located in the bolt hole and prevents insertion of the bolt when the bolt engaging groove and the bolt hole do not coincide with each other in the joint yoke, The joint yoke extends continuously from the shaft insertion hole side of the joint yoke, and the shaft insertion hole is sandwiched between the bolt holes. It is folded back at the edge of the outer surface of the joint yoke located on the opposite side closer to the inlet of the shaft insertion hole, and its end portion engages with the edge of the outer surface of the outer surface of the joint yoke farther from the inlet of the shaft insertion hole. An assembling structure characterized in that an erroneous assembly preventing member including a fixing portion is provided.
