摘要： A motion conversion mechanism comprising a threaded shaft and a nut, is disclosed. The nut comprises a cylindrical body having the inner surface thereof formed with a groove corresponding to the thread of the threaded shaft. A string having a low friction property surface is fitted in the groove such that it partly projects from the inner peripheral surface of the cylindrical body. The projecting portion of the string constitutes a thread to be screwed with the thread of the threaded shaft.
