属部品のプラスチック化の役割は大きい。In recent years, advances in plastic-related technology, especially in terms of materials, have been remarkable, with new materials created by combining various plastic materials,
Many reinforced plastic materials using reinforcing fillers have been developed, and their application fields are expanding as substitutes for metal parts. The conversion of metal parts into plastic plays a major role as a means of reducing the cost of current industrial products.

樹脂を用いることによって強度を保っている。On the other hand, the trend toward smaller and thinner watch parts has been stronger than before, but recently the trend has become even smaller and thinner, and many parts are difficult to make from plastic due to strength issues. For example, the center pipe of the main plate uses a thin metal pipe, and even when the main plate was made of plastic, the center pipe part had a composite structure with the metal pipe. However, there is a strong demand for loss-down, and plastic base plates with integrated central pipes have been commercialized using thermoplastic resin reinforced with glass fibers. In addition, the metal gears of watches have become thinner, and the thin plastic gears maintain their strength by using thermoplastic resin reinforced with glass fiber.

耗による精度低下等の問題が有った。However, in the case of watch parts molded from glass fiber-reinforced thermoplastic resin, although rigidity may be achieved in the thicker parts, the thinner parts are not filled with glass fibers, causing problems as strength and rigidity cannot be obtained. . In addition, the thin wall portions include sliding ends in most cases, and there are problems such as deformation due to insufficient strength and decreased accuracy due to wear.

題となっていた。Even in the above-mentioned plastic base plate with an integrated central pipe, if the wall thickness is equivalent to that of a conventional metal pipe, the glass fiber will not be filled in the pipe part and only thermoplastic resin will be left, and the strength and rigidity cannot be obtained, so the thick part will be smaller. The length of the pipe is short due to
There were problems such as a lack of stability in the axis alignment of a. In addition, thin gears made of plastic using glass fiber-reinforced thermoplastic resin have problems such as lack of strength and precision loss due to surface abrasion because the tooth profile tips are not filled with glass fiber. The charging of the plastic resin caused dust to adhere, which caused problems such as malfunctions.

The third wheel 6 is made of a material containing 20% by weight of needle-like ultra-short fibers 6C of potassium titanate, and the remainder is polyacetal resin. Although there are almost no fibers 6b, they are sufficiently reinforced with acicular ultrashort fibers 6C of potassium titanate. The third wheel 60 has strength, rigidity and anti-static properties due to the carbon fibers 6b filled in it, and titanium composite I is provided near the tooth tips 6a.

材料の組成が決まっている。The thermoplastic resin filler forming the watch component of the present invention is
If the weight ratio of both ultrashort fibers such as carbon fiber and carbon fiber milled fiber is less than 10%, no reinforcing effect can be obtained.
On the other hand, if the carbon fiber content exceeds 35% by weight, there are problems such as the inability to combine with other fillers, and ultrashort fibers such as carbon fiber milled fibers also have a content of 30% by weight. The composition of the material is determined because if it exceeds %, it will not be possible to form a composite.
