である。The output shaft 8 has its longitudinal direction IN! A screw thread 9 with the number 10 is carved on the i11 surface, and the above rotor 1 has this output #lt.
+ 8 (two screws are attached. Therefore, this output 1QI +
8, in order to prevent its rotation, a detent piece 10 is provided protruding from the rear end, and the guide member 11 is engaged with the rotation stopper 10.

紀ロータ１は出力軸８に対しナンドの作用をなすことか
ら、上記ロータｌが止転および逆転するに伴って上記出
力軸８が下降および上昇される。In the actuator having such a 4'A configuration, the C1 upper rotor 1 exerts a NAND action on the output shaft 8, so as the rotor I stops rotating and rotates in reverse, the output shaft 8 is lowered and raised. Ru.
すなわち、ロータ１の回転運動が出力軸８の直線運動に
変換烙Ｊする。したがって出力軸８の先端に負荷を接続
すれば、この負荷を往復動嘔せることができる。That is, the rotational motion of the rotor 1 is converted into the linear motion of the output shaft 8. Therefore, by connecting a load to the tip of the output shaft 8, this load can be reciprocated.
なお、上記ポテンショメータ１３の出力信号は上記出力
軸８の移動位置を示すので、この出力信号を出力軸８０
位誼決め制御に利用することができる。Note that since the output signal of the potentiometer 13 indicates the moving position of the output shaft 8, this output signal is transmitted to the output shaft 80.
It can be used for positioning control.
また、上記出力軸８としてネジ山間にボールを配したい
