<P>PROBLEM TO BE SOLVED: To provide a rotation-direct acting conversion actuator which can easily couple two partial housings and can easily be completed after coupling. Ž<P>SOLUTION: A nut 20a of a planet differential screw-type rotation-direct acting translator 20 is fitted into a front-side partial housing 10 through a bearing 16, and a stator 28 is fitted to a flange part 10b through a holding support 26. Thus, a rotor 22 can be inserted into the stator 28 only in the front-side partial housing 10 before the partial housings 10 and 12 are coupled in the housing 4. Thus, coupling work of the partial housings 10 and 12 is to insert a part where the stator 28 is confronted with the rotor 22 on a front-side partial housing 10-side into the rear-side partial housing 12 so as to couple them. Thus, the two partial housings 10 and 12 can easily be coupled and the actuator 2 can easily be completed after coupling. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
