PURPOSE:To attain a precise control, by providing tapered coupling parts of female and male shapes on the shaft end of an output shaft of a servomotor and an input shaft end of a rotation detector, and forming completely as one body a rotation transfer system path. CONSTITUTION:A servomotor 10 has a tapered shaft part 14 on the outside projecting end of an output shaft 12, and is axially supported by a rotary bearing 18 in a housing 16. Also, plural posts 20 are provided in the circumferential direction on an outside end face 16a of the housing 16 so they become equal in height from the outside end face 16a, respectively. On the other hand, a rotation detector 22 has a rotary input shaft 28 supported by a rotary bearing 26 in a housing 24, a tapered hole 30 having a complementary shape to the tapered shaft part 14 of the servomotor 10 is formed on the outside end of this rotary input shaft 28, and the tapered shaft part 14 of the servomotor 10 is fitted tightly into this tapered hole 30, by which the tightly fitted coupling as one body is attained between an output shaft 12 of the servomotor 10 and the input shaft 28 of the rotation detector 22. |
