長（かかり２回転エネルギも大きいので。The centrifuge rotor shown above has a rotation speed of +:ri
The higher the separation ability, the smaller the 1'17 particles can be separated. Conventionally, titanium alloys and aluminum alloys have often been used as the rotor material 11'1 for centrifuges. These materials have a relatively low specific gravity among metals and have high strength (high specific strength), so they are useful for Yr materials such as rotors, which are subject to centrifugal force. It has been used because it is. However, these metal materials have a larger specific gravity than the fiber-reinforced composite + A category used in the present invention. For this reason,
Rotors using these materials are heavy and inconvenient to carry and to attach and detach from a centrifuge. Also, because it is heavy, it takes a long time to accelerate and speed (because it takes a lot of rotational energy).
−万一の破壊に備えて、遠心機を強固なｔＩ１７１清に

ある。[Object 1 of the invention] [Object 1] of the invention is the above-mentioned conventional rotor firing 1. ! In addition to improving the shunting capacity by obtaining a higher rotation speed and reducing the weight of the centrifuge, improving operability and shortening the acceleration and deceleration time,
It is an object of the present invention to provide a rotor that can be integrated into a single rotor and miniaturized.

向を遠心力方向と一致させ、かつ。The present invention allows the fiber direction to match the direction of the centrifugal force with respect to the centrifugal force applied to the bucket into which the sample is inserted and the bucket support that supports the bucket.
繊維は連続したソート状プリプレグを用いている。Continuous sorted prepreg fibers are used.
これは、繊維が繊維方向には強度が高く、これと直角方
向には弱く、また、連続して巻き付けたものが強いとい
う特性に着目したらのである。なお。This is because fibers are strong in the fiber direction, weak in the direction perpendicular to the fiber direction, and strong when continuously wound. In addition.
これらの材料は、チタン合金などに比べて比強度が高い
ものが容易に入手できる。These materials have higher specific strength than titanium alloys and the like and are easily available.
