し曲は及び／又は捩れが生ずる。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to flexible boots. As shown in FIG. 1, the flexible boot 2 is used to retain Namekawa grease on constant velocity joints, 1st steering mechanisms, etc., and to completely prevent dust, water, etc. from entering from the outside. The flexible boot 2 is fixed to the outer ring 6 of the joint 5 and the shaft 8 by clamps 4, 4', and bends and/or twists following the shaft 8.

ると、フレキシブルブーツ２は破損してしまう。When the flexible boot 2 is bent and/or twisted, the outer peripheral surfaces thereof come into contact with each other and exert a force on each other. The flexible boot 2 is made of natural rubber or synthetic rubber, and if the flexible boot 2 is rotated at high speed in a bent and/or wet state, the flexible boot 2 will be damaged.

に補強層のためフレキシブルブーツの伸縮性が低下して
、フレキシブルブーツの機能を損なってしまう。In order to prevent this, it is known to use a flexible boot whose outer peripheral surface is coated with a heat-shrinkable material to form a reinforcing layer. However, in this case, it is difficult to keep the reinforcing layer in constant contact with the flexible boot body, and conversely, the reinforcing layer reduces the elasticity of the flexible boot, impairing its functionality.

したことを特徴とするフレキシブルブーツである。The present invention has been made with the aim of improving these drawbacks of conventional flexible boots. The flexible boots of the present invention are characterized in that short fibers are flocked on the outer peripheral surface, a stretchable coating is formed thereon, and short fibers are further flocked on the coating.

7" Neil is preferably 1.0 to 30. Short R11 fibers of stubble may be used for the outer peripheral surface and the stretchable coating.
伸縮性被膜としてはウレタン系のものが望ましい。As the stretchable film, a urethane-based film is preferable.
この発明のフレキシブルブーツの製造はたとえば次のよ
うに行なう。第２図に基づいて説明する。The flexible boots of the present invention are manufactured, for example, as follows. This will be explained based on FIG.

件としては１４０〜１５０°Ｃ×１０〜３０分が好まし
い。First, the outer peripheral surface of the flexible boot body 10 is treated with a primer. Such treatment methods include an ultraviolet treatment method and a pickling method using a 2% methylene chloride solution of trichlorocyanuric acid. Next, apply adhesive to the outer peripheral surface. As the adhesive, urethane-based, acrylic-based, and rubber-based adhesives are preferred. Further, the thickness of the film is preferably 0.1 to 0.6 questions. After applying the eyebrow agent, short fibers are implanted and fecalized in the next layer. The curing conditions are preferably 140 to 150°C x 10 to 30 minutes.
以上の方法のはかに、機械的方法によって植毛してもよ
い。In addition to the above methods, hair transplantation may also be performed using a mechanical method.
該植毛の上に伸縮性被膜材料を塗布し硬化させる。A stretchable coating material is applied over the flock and cured.
被膜の上に梃に短繊維を植毛する。Short fibers are grafted onto the coating.
本発明は以上のように構成したので伸縮性を損なうこと
