ABSTRACT:
There is provided an apparatus for preventing displacement of a retainer in a rolling guide by making use of the property of the retainer of moving half the distance of a moving object, such as a table. The apparatus for preventing displacement of a retainer in a guide apparatus having a plurality of finite rollers held by retainers and including a guide mechanism for guiding the movement of a moving object of a machine tool along guide surfaces of a bed or a saddle, and a linear motor feed mechanism for feeding the moving object, includes: a displacement regulator having a stopper for regulating the position of each retainer, the regulator being movable in conjunction of the movement of the moving object; a line of magnet plates of a linear motor for driving of the moving object, the line of magnetic plates being a constituent of a linear motor feed mechanism for the moving object and being arranged parallel to the guide surfaces; a linear motor mechanism for moving the displacement regulator in the same direction as the moving direction of the moving body; and a linear motor control means for moving the displacement regulator in synchronization with the movement of the moving object at a velocity which is one-half of the velocity of the moving object.
