Abstract
A comb structure in which a magnetic force, which is generated between a pair of intermeshed combs by applying a magnetic flux thereto, is constant with respect to the relative motion between the combs, is provided. Also, an actuator and an inertia sensor both using the comb structure are provided. The comb structure includes a pair of magnetic combs, a magnetic flux guide for magnetically connecting the pair of combs, a coil wound around an arbitrary portion of the magnetic flux guide, and a power supply connected to the coil. The pair of magnetic combs intermeshed with each other having a gap S therebetween are connected to each other by the magnetic flux guide, such that they are driven by receiving a magnetic field from the coil. The coil is supposed to generate a magnetic field under the influence of a current provided from the power supply.
