従来の技術とその問題点
ｆへｌ）ブツシュ組立体（摺動タイプのブツシュ組立体

シールが必要な企めに構造が複雑化し、コスト高になる
欠点がある。Go to Conventional Technology and its Problems f) The bushing assembly (sliding type bushing assembly) is different from the type that dampens vibration by using the screw stiffness of the rubber itself. By providing a sliding part, the relative rotational displacement of the sliding part is used to reduce torsional rigidity and improve torsional durability, but generally the number of parts increases and at the same time a seal against dust and water is required. However, this approach has the disadvantage of complicating the structure and increasing costs.

でダストシール対策を施している。For example, the VesiPush assembly shown in Japanese Patent Publication No. 44-20683 has a flange portion 21 as shown in FIG.
A sliding body 2 made of resin is placed between the inner cylinder 20 and the rubber body 22.
3 to generate a gap between the inner cylinder 20 and the sliding body 23, while the flange portions 21 and 25 of the inner cylinder 20 and the sliding body 23 are held by the flange lip 24 to take measures against dust sealing. .

を発揮できないことがある。However, in order to process the inner cylinder 20, simply press working is not enough, and cutting work is also required, which increases the number of processing steps and increases costs. In addition,
To make sure that the flange lip 24 is in elastic contact with the seventh rank part 21 of the inner cylinder 20, when the inner cylinder 20 and the sliding body 23 slide, the contact between the flange lip 24 and the seventh rank part 21 acts as resistance, and the screw The stiffness may increase and the original sliding/pushing characteristics may not be exhibited.
また実開昭６０−１６１７３号公報のすベシブツシ二組
立体においては、内筒、摺動体、ゴム体。In addition, in the subassembly two assembly disclosed in Japanese Utility Model Application Publication No. 60-16173, an inner cylinder, a sliding body, and a rubber body.
外筒の４層構造に加えて、摺動体とゴム体の間に中間筒
を介在させ念ものであυ、先に例示したものに比べて一
層構造を複雑なものにしている。In addition to the four-layered structure of the outer cylinder, an intermediate cylinder is interposed between the sliding body and the rubber body, making the structure more complicated than the previous example.

A large-diameter 7-rank part extending parallel to the axial direction is formed at the end of the rubber body, and a seal lip that comes into elastic contact with the inner periphery of the flange part is formed protruding from the end of the rubber body. It is.

、すベシプッシュ組立体１は金属製の内筒２と、切損ゴ
ム体（以下、単にゴム体という）３と、合成樹脂製の摺
動体４と、金属製の外筒５とで構成されている。Effect: According to the above structure, for example, torsional rigidity is reduced by relative rotational displacement between the sliding body and the outer cylinder. Since the tip of the seal lip is in elastic contact with the inner periphery of the flange of the outer cylinder, there is no possibility of dust entering.Embodiment Figures 1 and 2 are diagrams showing an embodiment of the present invention. Yes, the push assembly 1 is composed of an inner cylinder 2 made of metal, a cut rubber body (hereinafter simply referred to as the rubber body) 3, a sliding body 4 made of synthetic resin, and an outer cylinder 5 made of metal. ing.

複数の凹溝７が形成されている。そして、突条６と凹溝
７とを合わせた上でゴム体３と摺動体４とを圧入するこ
とにより両者が相対回転不能に拘束されている。The rubber body 3 is integrally fixed to the inner cylinder 2 by, for example, baking (vulcanization) adhesion. 1. A plurality of ridges 6 extending in the axial direction are formed on the outer surface of the rubber body 3 as shown in FIG. 2, while the inner peripheral surface of the sliding body 4 corresponds to the ridges 6. A plurality of grooves 7 are formed. Then, by aligning the protrusion 6 and the groove 7 and then press-fitting the rubber body 3 and the sliding body 4, both are restrained so that they cannot rotate relative to each other.
摺動体４の材質としては摩擦抵抗がきわめて小さい低摩
擦材、例えば分子量が２００〜３００万の超高分子ポリ
エチレンを使用する。As the material of the sliding body 4, a low-friction material with extremely low frictional resistance, such as ultra-high molecular weight polyethylene with a molecular weight of 2 million to 3 million, is used.

動部分へのダストの進入を防止している。A lip 8 is attached to one end of the rubber body 3, and a large diameter 7 is attached to the other end.
A rank portion 9 is formed on each of the flange portions 9, and a seal lip 10 extending in the radial direction is provided on the outer periphery of the flange portion 9. On the other hand, at the other end of the outer cylinder 5, a seven-rank portion 11 having a large diameter and extending parallel to the axial direction is formed. By slidably fitting the sliding body 4 and the outer cylinder 5, the lip 8 comes into elastic contact with one end surface of the outer wJ 5, and the seal lip 10 comes into elastic contact with the inner periphery of the 7-rank part 11. This prevents dust from entering the sliding portion.

じない。Here, the VesiPush assembly 1 constructed as described above is used in the assembled state shown in FIG. 3, for example. That is,
The shaft 14 of one member 13 is inserted into the inner cylinder 2,
The other member 15 is inserted into the outer cylinder 5. In this state,
For example, when vibration in a direction perpendicular to the axis of the shirt 14 does not act between the two members 13 and 15, the elastic deformation of the rubber body 3 exerts a vibration-proofing effect. When no vibration in the thread direction is applied around the shaft 14, the outer cylinder 5 and the sliding body 4 rotate relative to each other to produce a so-called slippage, thereby reducing the torsional rigidity in the thread direction. In this case, 7
Since the contact area of the seal lip 10 with the rank portion 11 is very small, problems such as increased screw rigidity do not occur.

分に発揮できる。Effects of the Invention According to the present invention, it is possible to reduce costs because the inner cylinder is made of a simple pipe material, and the original characteristics of BesiPush can be fully demonstrated despite the simple four-layer structure. .
