<P>PROBLEM TO BE SOLVED: To provide a telescopic motion mechanism can improve assembly accuracy of each component and improve quality. Ž<P>SOLUTION: The telescopic motion mechanism 30 is provided with a motor 34 as a drive source, a reduction gear 36 reducing rotation speed of the motor 34, a feed screw 38 to which rotary force of the motor 34 of which speed is reduced by the reduction gear 36 is transmitted via a coupling 37, a nut part 39 meshed with the feed screw 38 and converting rotary force to linear force, and one side and another side housings 31, 32 storing the motor 34, the reduction gear 36, the coupling 37, the feed screw 38, and the nut part 39 and having a structure divided into two. The motor 34 and the reduction gear 36 is exclusively stored in the one side housing 31. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
