Abstract
This actuator has a fixing member and a member to be driven which is relatively movable with respect to the fixing member. On a pair of opposing surfaces where the member to be driven and the fixing member oppose each other, opposing magnetic members that repulse each other due to respective magnetic forces and form a predetermined space along the Z-axis are disposed. The fixing member is provided with a first magnetic field generation unit that causes magnetic force to act on the magnetic member provided in the member to be driven.
Claims15
An actuator comprising:
- a fixed member;
- and
- a driven member relatively movable with respect to the fixed member,
- wherein
- opposing magnetic members in pairs repelling each other using magnetic force to provide a predetermined space therebetween along a first axis are disposed on opposing surfaces in pairs of the driven member and the fixed member respectively;
- and
- the fixed member is provided with a first magnetic field generating portion configured to exert magnetic force on at least one of the opposing magnetic members provided for the driven member to change a length of the predetermined space between the opposing magnetic members.
