ABSTRACT:
Disclosed is an actuator having a frame in which a drive source and a slider displaced under the action of the drive source are held, and an actuator arrangement comprising a plurality of actuators connected to each other by connecting devices. A beam member, which constitutes the frame, has a concave portion defined in a side thereof and the drive source is held in the concave portion. A slider base is held in the concave portion and includes the slider displaced along the concave portion. A cover is used to cover the concave portion defined in the beam member. The beam member has grooves defined in respective outer sides thereof, which have substantially T-shaped cross sections and enable other beam members to be mounted to the beam member. The grooves are defined along the longitudinal direction thereof so as to be substantially identical in structure to one another. According to the above construction, either other beam members or the actuators can be connected to one another by means of the grooves so as to assemble a desired actuator arrangement having a desired shape, thereby making it possible to place the actuator arrangement on a production line in a factory.
