Abstract

An electric actuator comprises a rotary driving source, a timing belt which is circled or orbited under the driving action of the rotary driving source, a slider which is displaced by the timing belt in the axial direction, and a belt-adjusting mechanism which is connected to a side surface of the slider. Both ends of the timing belt are connected to the belt-adjusting mechanism respectively. The tension of the timing belt is adjusted by rotating an adjusting screw of the belt-adjusting mechanism.
