Abstract

PURPOSE: To stably drive a moving part, by causing a guide member to serve both as a driving part constituting a magnetic circuit and as a guide part.
CONSTITUTION: Magnetic circuits are constituted by yokes 1∼4. A round bar core 5 is secured between the yokes 3, 4 so that both the ends of the core are tightly fitted on the yokes. Magnets 6, 7 whose front and rear are magnetized as an N-pole and an S-pole are bonded on the inside surfaces of the yokes 1, 2. Gaps 8, 9 are defined between the core 5 and the magnets 6, 7. A bobbin 10 of U-shaped cross section is movably fitted around the core 5. A driving coil 11 is provided around the bobbin 10. The inside and outside diameters of the bobbin 10 are so set that it can smoothly slide without play on the core 5. As a result, a moving part smoothly moves without play and the deterioration in performance or the like due to vibration is prevented.
