ABSTRACT:
A rotary actuator is designed for rotatingly drive a rotary body, such as a rotary valve member for adjusting damping force to be created by a variable damping force shock absorber. The rotary actuator takes a layout of a permanent magnet and an electromagnet arranged in vertically spaced relationship. Vertical layout of the permanent magnet and the electromagnet reduces plane area required for installation.
