ABSTRACT:
A moving coil type linear motor in which yokes disposed opposite to magnets magnetized in the thickness direction thereof penetrate through-holes of a bobbin on which a coil is wound that is energized to generate the magnetic flux which intersects the magnetic flux of the magnets, and the bobbin is moved along the yokes by energizing the coil, wherein a guiding portion for guiding a rolling element including balls, for example, is provided in the surfaces of the respective yokes which do not face the magnets and the through-holes of the bobbin, to thereby support the bobbin on the yokes through the rolling elements.
