いられている。DETAILED DESCRIPTION OF THE INVENTION (Prior Art and Problems) In recent years, the use of materials in which a polyamide resin is used as a matrix material and a reinforcing agent or filler is blended therein has been increasing. These materials are formed into shapes using currently commonly used injection molding or extrusion molding methods, and are used for their respective purposes.
こうした用途分野の一つに高比重な材料を要求されるは
ずみ車や慣性歯車がある。これらは何れも物体の有する
慣性力を利用して滑らかな回転を与えるものである。従
って慣性力を太き（保らうる、即ち比重の大きな材料で
形成されたものの方が小さくとも大きな慣性力を得るこ
とができるため小さな空間で使用するのに有利である。One such application field is flywheels and inertia gears, which require materials with high specific gravity. All of these utilize the inertial force of an object to provide smooth rotation. Therefore, a material that is thicker (able to maintain the inertial force), that is, made of a material with a large specific gravity, is advantageous for use in a small space because a large inertial force can be obtained even if the inertial force is small.
また、これらの材料はバランスがとれていることも必要
である。バランスを欠いたものでは慣性力が不均一とな
り、軸の振れ、回転ム・うとなってあられれる。It is also necessary that these materials be well balanced. If an object lacks balance, the inertial force will be uneven, resulting in shaft wobbling, rotational movement, and distortion.

十分には満足し得ない。However, conventionally known resin compositions using polyamide resin as a matrix material cannot fully satisfy the above requirements.

ものである。The inventor of the present invention has made intensive studies to satisfy these requirements, and as a result, we have developed a high specific gravity polyamide resin that 1) has excellent moldability, 2) has sufficient uniformity of the molded product, and 3) has a high specific gravity and is resistant to external forces. A molding material composition has been found and is the object of the present invention.

ンス良く均一に分散しているものである。Powders such as Pb, Cu, alloys and oxides thereof are used as the metal powder, but iron powder is most preferable from the viewpoint of cost. Furthermore, in addition to the polyamide resin and metal powder, silane or a titanium coupling agent can also be added as a binder for these. The present invention is characterized in that it is a mixed material containing metal powder stearate and a plasticizer added to a composition mainly composed of the metal powder and polyamide resin, and the metal powder is uniformly dispersed in a well-balanced manner. It is something that exists.

It is 20% by weight. The metal powder used in the present invention may be obtained by any method. The shape of the metal powder may be any shape, but it is preferable that it be more spherical than angular metal powder. Square metal powder is material number 8! This not only impairs the movement of the resin composition but also tends to wear out the equipment used to obtain the molded product, and as a result, there is a risk that foreign matter may stagnate in the molded product.
