【考案の詳細な説明】
この考案は、外周に球面状のすべり面をもち、
角変位を可能にするボールジヨイントの改良に関
するもので、製作の簡易化とコストの低減を目的
とするものである。[Detailed explanation of the invention] This invention has a spherical sliding surface on the outer periphery,
This relates to improvements to ball joints that enable angular displacement, and aims to simplify manufacturing and reduce costs.

ングリング４′を嵌着した後、外周に球面状のす
べり面をもつ球体部５′を嵌入して結合する。 As shown in Fig. 1, a conventional ball joint consists of a ball housing 1' with a bottom, and a stopper ring 4' that fits into a ball housing hole 2'. This is common. The work procedure is
After fitting the stopper ring 4' into the storage hole 2' of the ball housing 1', a spherical part 5' having a spherical sliding surface on the outer periphery is fitted and connected.

分にあり好ましくなかつた。また、ジヨイント本
体であるボールハウジング１′の製造は鍛造によ
るため、比較的コストも高くつくという欠点があ
つた。 However, with this type of ball joint, there is no problem with the compressive force acting on the spherical part 5' among the forces acting in the axial direction of the storage hole 2', but with respect to the tensile force the stopper ring 4 Since the structure is such that the spherical part 5' only corresponds to the accommodating hole 2', there is a high possibility that the spherical part 5' will come off from the storage hole 2' when a strong tensile force is applied, which is undesirable. In addition, since the ball housing 1', which is the joint body, is manufactured by forging, there is a drawback that the cost is relatively high.
この考案は、従来の前記問題を解決するために
なされたもので、構造簡単でかつ性能的にもすぐ
れ、さらに製造コストが安価につくボールジヨイ
ントを提供するものである。 This invention was made to solve the above-mentioned conventional problems, and provides a ball joint that is simple in structure, has excellent performance, and is inexpensive to manufacture.

である。 That is, in this invention, the joint body is constructed from a single flat plate, and the joint body is formed by alternately bending the joint body between the notches made radially from the inner periphery of the connecting hole drilled in the flat plate. A spherical part having a spherical sliding surface on the outer periphery is fitted inside a plurality of protruding pieces, and then each protruding piece is caulked so as to surround the spherical part.

離脱防止効果を考慮すれば、スプリングバツク効
果を有するばね鋼等が好ましい。 Figures 2 and 3 show one embodiment of this invention, in which 1 is a joint body formed from a single flat plate into a predetermined shape, 2 is a connection hole, and 3 is a cut. A spherical part 5 is inserted into the inner center of a plurality of protruding pieces 4 which are formed by bending the protruding pieces 4 in opposite directions alternately by pressing or the like, and then each protruding piece 4 is inserted so as to surround the spherical part. It is connected to the joint body 1 by caulking. In addition,
It goes without saying that the connection hole 2 previously drilled in the joint body 1 has a smaller diameter than the diameter of the spherical part 5. Further, the material of the joint body 1 is not particularly limited, but in view of the effect of preventing the spherical part 5 from coming off, spring steel having a spring back effect is preferable.

造によるものに比べ製造コストが安価につく利点
がある。 In the case of a ball joint with the above structure, the spherical part 5
is surrounded and caulked by a plurality of protruding pieces 4, so each protruding piece serves both a joint function and a stopper function. Therefore, not only is the conventional stopper ring unnecessary, but also large pull-out strength and compression strength are obtained, and the effect of preventing the spherical part from coming off is great. Also, in terms of processing,
This method has the advantage of being cheaper to manufacture than conventional forging, as it only requires cutting holes for joining into the plate-shaped joint body and pressing.
この考案は上記のごとく、構造が簡単でかつ継
手性能がすぐれ、しかも製造コストが安価につく
ため、極めて有用性に富むものである。 As mentioned above, this invention is extremely useful because it has a simple structure, excellent joint performance, and low manufacturing cost.
