摘要： A track rail is formed in a channel-like configuration while having a guide passage for sliders. A table structure that moves within the guide passage includes: a pair of sliders that move forwards and backwards within the guide passage; and a connecting top board connecting those sliders to each other with a predetermined interval therebetween and provided with a mounting surface for a movable member. An armature constituting a linear motor is received between the pair of sliders, and field magnets constituting the linear motor are arranged in the track rail so as to face the guide passage. The armature and the field magnets, which constitute the linear motor, are completely integrated with the table structure and the track rail, which constitute a linear guide, and are entirely contained inside the linear guide.

摘要： An electric actuator is provided with a power transmission mechanism capable of converting a rotating driving power supplied from an electric motor to a reciprocating motion. This power transmission mechanism is provided with a cylindrical member formed, in its inner peripheral surface, with at least one row of rolling member rolling groove, a nut member disposed to be reciprocally through the rolling members endlessly circulating in the inner peripheral surface of the cylindrical member, and a cylinder rod operatively connected to an end portion of the nut member to be axially movable with respect to the cylindrical member. The reciprocating motion of the nut member in the axial direction is guided by the circular cylindrical member. According to such structure, high output and high controllability can be realized, as well as realizing of a compact electric actuator of a size similar to a conventional hydraulic cylinder.
