Abstract
A slider unit having built in a moving-coil linear motor is incorporated in a linear motion guide unit having a track rail and a slide. The slider unit is made easy in mounting to the appliances or works. The linear motion guide unit has the track rail and the slider movable lengthwise of the track rail. A linear motor is arranged between any one of widthwise opposing side walls of the track rail and the slider, and composed of a stator comprising a magnet yoke and field magnets, and a moving-coil assembly held on a side edge of a mount of the slider. The linear motor is preferred to make compact or slim in construction the linear motion guide unit, in which the linear motor is incorporated, thus making the slider unit simple in construction.
