【考案の詳細な説明】
本考案は自動車等のスライド軸摺動部の水、ダ
スト等の侵入を防止するためのダストブーツに関
するものである。[Detailed Description of the Invention] The present invention relates to a dust boot for preventing water, dust, etc. from entering the sliding portion of a slide shaft of an automobile or the like.
軸方向に相対的に移動する部品間のダストシー

ーツ状部が長いため小石、水等が当りブーツ部が
変形しやすかつた。 Conventionally, in dust sealing devices between parts that move relatively in the axial direction, a corrugated dust boot connects and covers the part where the mating part (ball stud, etc.) fits and the part where it is attached to the other mating part. Since the boot-shaped part was long, the boot part was easily deformed by contact with pebbles, water, etc.

ライド作動時ブーツ状部を噛込んだりしてダスト
ブーツ部が切損するか、又接触摩耗大等によりい
ちじるしく耐久性及びシール性が低下していた。 Furthermore, the boot-shaped portion may drop due to its own weight, and may become caught in the dust boot during sliding operation, resulting in breakage of the dust boot portion. Furthermore, the durability and sealing performance of the dust boot may be significantly reduced due to large contact wear, etc.
本考案は上記従来の欠点を解消せんとするもの
で、以下附図に示す実施例につき説明する。 The present invention aims to solve the above-mentioned conventional drawbacks, and will be described below with reference to the embodiments shown in the accompanying drawings.

is a dust boot with a fitting part 6 for the ball stud 1 at the tip, a flexible conical cylindrical boot part 7 that opens and extends from this in a cone shape, and a slightly larger diameter end of the conical cylindrical boot part 7. Highly rigid cylindrical support part 8
The end of the cylindrical support portion 8 is configured as a support portion 9 that fits into the housing 4. 1
0 and 11 are clamps, and 12 is a bearing.

できる。 With the above configuration, when the rack shaft 3 slides in the axial direction with respect to the housing 4 and the ball stud 1 and ball joint assembly 2 are displaced in the axial direction from A to B and C, the conical cylindrical boot portion 7
Due to its flexibility, the small diameter part can bend and fit comfortably inside the large diameter part and further into the cylindrical support part 8 as shown by the chain line. The portion 8 can support such deformation of the conical cylindrical boot portion 7 with high rigidity.

部材の効果を大ならしめるものである。 If a reinforcing member 8' is inserted or provided in the cylindrical support portion 8 as shown in FIG. 2, the effect of the support member will be further enhanced.

ものである。 As described above, according to the present invention, the dust boot between two members that move relatively in the axial direction is formed by a flexible conical cylinder that opens in a cone shape and extends from the fitting part to the small diameter part of one member. By having a structure in which these parts are integrally molded as a support part that connects the end of the cylindrical support part to the other member, the cylindrical support part has a slightly rigid cylindrical support part extending from the large diameter end of the boot part. When the member moves relatively in the axial direction, the flexible conical cylindrical boot section is bent and deformed while being supported by the highly rigid cylindrical support section, and easily enters the inside of the cylindrical support section. Therefore, it is possible to obtain a deformation stroke that is much larger than the length of the conical cylindrical portion, and the overall length of the dust boot can be shortened and the weight can be significantly reduced compared to the conventional wave-shaped dust boot. Therefore, it is possible to completely prevent the dust boot portion from falling, and it is possible to improve durability. Also, compared to conventional wave-shaped dust boots, the shape is simpler, easier to process, and less expensive. Furthermore, the cylindrical support portion prevents deformation even when hit by stones, water, etc., thereby improving durability.
