Abstract
PURPOSE:To reduce the number of assembly parts and to simplify assembly work by integrating constitution parts. CONSTITUTION:A titled structure consists of a fixed guide rod 5, a moving part 30 which is held by the outer periphery of the guide rod 5 through a bearing, freely shifts along the lengthwise direction, and is fitted to a carriage, a yoke 9 in which the moving part 30 is accommodated, whose one end is opened, and whose other end has a base plate 31 fixed by the guide rod 5, and the magnetic flux generation part of permanent magnets 7 or electromagnets provided on the inner side of the yoke 9. The magnetic flux of the magnetic flux generation part flows through the yoke 9 and the guide rod 5, is efficiently supplied to driving coils 8, and it gives propulsion force to the moving part 30, which is guided along the guide rod 5 through the bearing. Thus, the guide rod 5 is integrated with the yoke 9 and the number of assembly parts reduces, whereby assembly work can be simplified.
