<P>PROBLEM TO BE SOLVED: To provide a technology to suppress rotation of a moving body to a guide member with simple configuration, despite a motion guide device capable of obtaining brisk motion. <P>SOLUTION: The motion guide device includes a shaft 1 and a nut unit 2 for guiding the shaft 1 so as to be reciprocated and rotated, Four magnetic body portions 3a to 3d made of magnetic body are provided at 90 degree intervals in the shaft 1, and permanent magnet portions 5a to 5d made of permanent magnet are provided at 90 degree intervals in the nut unit 2. Magnetic body portions 3a to 3d are attracted by permanent magnet portions 5a to 5d by magnetic force generated from permanent magnet portions 5a to 5d, and an angle of the shaft 1 to the nut unit 2 is maintained. <P>COPYRIGHT: (C)2012,JPO&INPIT |
