摘要： Plastic dust-proof boots which are made of thermoplastic resin by means of blow molding and provided at least on one end of a bellows with a stationary ring to be fitted to an engaging groove formed on an attaching shaft and methods for manufacturing the plastic boots. In the boots, an inner circumference base upright wall of the stationary ring is formed at a nearly vertical state, and the inner circumference base upright wall of the stationary ring is connected through a sleeve having an inner diameter so that the attaching shaft can be loosely fitted. In manufacturing the boots, the stationary ring and the sleeve are molded during the parison molding previously or during mold tightening at the blow molding stage, and the blow molding is performed while the stationary ring and the sleeve are grasped between molds. Accordingly, the base upright wall of the stationary ring is securely locked to the engaging groove, and the boots having the base upright wall of such shaft form can be easily molded in the blow molding process.

摘要翻译： 通过吹塑成型由热塑性树脂制成的塑料防尘靴，并且至少在具有固定环的波纹管的一端上设置以装配到形成在连接轴上的接合槽和用于制造塑料靴的方法。 在靴子中，固定环的内圆周底部直立壁形成为几乎垂直的状态，并且固定环的内周底直立壁通过具有内径的套筒连接，使得连接轴可以松动 适合。 在制造靴子时，固定环和套筒在预先形成的型坯模制期间或在吹塑成型阶段的模具紧固期间被模制，并且在固定环和套筒被夹持在模具之间时进行吹塑。 因此，固定环的基部直立壁牢固地锁定到接合槽，并且具有这种轴形式的基部直立壁的靴可以在吹塑成型过程中容易地模制。

摘要： A dust boot for a universal joint covering two joint elements having largely curved corner portions in the outer peripheral surface thereof near their joint portion, comprises a resilient annular covering portion for covering the joint portion of the universal joint and two annular end portions which are integrally formed with the covering portion in axially both ends thereof. The annular end portions are mounted on the two joint elements near their joint portion. Since the area of an open end of the dust boot mounted on the joint element having largely curved corner portions is made smaller than the cross sectional area of the outer peripheral surface of the joint element, specifically only the curvature of the open end of the dust boot corresponding to the largely curved corner portions of the joint element is made smaller than that of the corner portions of the joint element, the dust boot can be closely mounted on the joint element with excellent sealing effect.

摘要翻译： 一种用于万向接头的防尘罩，其覆盖在其接合部分的外周表面处具有大的弯曲角部的两个接头元件，包括用于覆盖万向接头的接合部分的弹性环形覆盖部分和一体的两个环形端部 在其两端形成有覆盖部分。 环形端部在其接合部分附近安装在两个接头元件上。 由于安装在具有大的弯曲角部的关节元件上的防尘罩的开口端的面积小于接头元件的外周面的截面面积，具体地仅仅是灰尘的开口端的曲率 与接头元件的大部分弯曲的角部相对应的靴子被制成小于接头元件的角部的靴子，防尘罩可以以良好的密封效果紧密地安装在接头元件上。

摘要： A rack boot which is installed at the steering rack portion of an automobile comprises a small-diameter ring portion, a large-diameter ring portion, and a bellows portion interposed between the small-diameter portion and the large-diameter portion. An angle to an axial line of the boot of a slanted wall of a first crest in the bellows portion is arranged to be 70.degree. to 85.degree., whereby the slanted wall is turned in when the boot contracts to an extreme extent. As a result, the shrinkage ratio of the boot in the axial direction can be increased without any necessity to enlarge the outer diameter of the crest portion of the boot or to increase the number of crests. Consequently, the size of the rack boot can be reduced.
