る。[Detailed description of the invention] This invention is a connection structure, specifically, when connecting a shaft and a boss by serration or spline connection, it is possible to determine the relative position of the shaft and boss in the rotational direction around the axis. Regarding possible connection structures.

いようにして、行なつていた。 Conventionally, this type of connection structure includes, for example, those shown in FIGS. 1 and 2. That is, the shaft 1 is provided with serrations 2 on its circumferential surface,
A notch 3 is provided in a part of the circumferential surface. The boss 4 has a hole 5, and a serration 6 that fits with the serration 2 of the shaft 1 is provided on the inner circumferential surface of the hole 5, and a relief portion 7 is formed in the hole 5 so that a portion is open. , is the tightening allowance for hole 5. A pair of ears 8 and 9 protruding outward is provided at the location where the relief portion 7 of the boss 4 is formed, and bolt insertion holes 10 and 11 are formed in the ears 8 and 9. When connecting the shaft 1 and the boss 4 by serration connection, the relative positioning of the shaft 1 and the boss 4 in the rotational direction around the axis is as shown in FIG.
If the notch 3 does not come to the position of the relief part 7, the bolt 12 for tightening the hole 5 can be inserted into this notch 3. This was done in such a way that it was not possible to insert it.
しかしながら、このような従来の連結構造にあ

工が複雑になり、製造コストが上昇するという問
題点があつた。 However, in such a conventional connection structure, since the notch 3 is provided in the shaft 1, cutting of the shaft 1 is required, which complicates the machining of the shaft 1 and increases manufacturing costs. There was a problem with that.

た。 In addition, as another conventional connection structure, there is one in which the shaft and the boss are each marked with paint or the like, and the relative positioning in the rotational direction around the shaft is visually determined when the shaft and the boss are connected. However, this connection structure has a problem in that the shaft and the boss can be connected at positions other than the predetermined positions, and therefore, the connection may be made at the wrong position, resulting in low reliability.

た。 Furthermore, in order to determine the relative positioning of the boss and the shaft in the rotational direction around the axis, a part of the spline between the boss and the shaft is formed so that the meshing width of a part of the spline is different from the meshing width of the other part. −21053 (Jikko Sho 54−
No. 41882) The spline according to the publication, and the spline of the shaft in which one of the teeth of the spline is shaved off, and a separate member is inserted in one place between the adjacent teeth of the spline of the cylinder. There is such a spline.
However, the former requires complicated cutting and increases the processing cost, while the latter requires a separate member and the number of man-hours required to insert and hold it between the female spline teeth, resulting in the same high cost as the former. .

ている。 This idea was made by focusing on these conventional problems.The tooth is crushed in the part facing the relief part of the serration or spline of the shaft, and the tooth thickness is greater than the tooth groove width of the serration or spline on the boss side. A crushed portion formed to be larger and a relief portion provided in a part of the serration or spline of the boss to correspond to the crushed portion of the shaft, so that when connecting the shaft and the boss, both It is an object of the present invention to solve the above-mentioned problems by making it possible to perform relative positioning in the rotational direction around the axis of the motor.

That is, the shaft 13 is provided with a pinion at its other end (not shown), the serrations 14 on one end are fitted into the serrations 18 of the boss 16, and the bolts 29 and nuts 30 are inserted into the ears 20, 21 of the boss 16. It is connected to the boss 16 by being fastened by. A yoke 31 constituting the universal joint 28 is provided on the opposite side of the boss 16 from the hole 17. 32 is a rubber coupling ring, and 33 is another universal joint, one end of which is connected to the steering wheel 24.
It is connected to a shaft (not shown). 34 is a housing for storing a rack therein; 35,
36 is a ball joint, and 37 is a stabilizer.

ことが防止される。 In the above-mentioned steering device, it is necessary to connect the steering wheel 24 in the same direction as the operating wheels 25 and 26,
For this reason, when connecting the shaft 13 and the boss 16 during assembly, it is necessary to determine the relative positional relationship between the two in the rotational direction around the shaft. In this embodiment, when the shaft 13 and the boss 16 are connected by serration, as shown in FIG. Assume that when the two come to the position, they are in a predetermined relative positional relationship in the direction of rotation around the axis. When the shaft 13 and the boss 16 are in a predetermined relative positional relationship in the rotational direction around the shaft, that is, when the crushed portion 15 is at the position of the relief portion 19, the shaft 13 is Because it is located in the same position, it is inserted into the boss 16 without hitting the serrations 18 of the boss 16, and the two are serration-fitted. Then, the shaft 13 and the boss 16 are connected by inserting the bolts 29 into the bolt insertion holes 22 and 23 and fastening them with the nuts 30.
Next, when the shaft 13 and the boss 16 are not in a predetermined relative positional relationship in the rotational direction around the shaft, that is, when the crushed portion 15 is located at a position other than the relief portion 19, the shaft 13 is The portion where the tooth thickness of the boss 15 is larger than the tooth groove width of the serrations 18 of the boss 16 comes into contact with the teeth of the serrations 18 of the boss 16, so that it cannot be inserted into the boss 16. For this reason, axis 1
3 and the boss 16 are prevented from being connected in a wrong relative position other than at a predetermined position in the direction of rotation around the axis.
なお、軸とボスとにセレーシヨンを設けた連結

る。 As explained above, according to this invention, the structure includes a shaft provided with serrations or splines, and a boss provided with serrations or splines that engages with the serrations or splines of this shaft. In the connecting structure, a crushed part is formed by crushing the teeth of the shaft so that the tooth thickness is larger than the tooth groove width of the boss serration or spline, and the boss's serration or Since a part of the spline is provided with a relief part provided corresponding to the crushed part, the crushed part can be provided by a simple process of crushing the serration of the shaft or a part of the spline with a press or a hammer. This has the effect of reducing manufacturing costs.
