Abstract
A linear guide mechanism includes an actuator side guide member, moving block side guide members disposed on both sides of the actuator side guide member, and a plurality of balls disposed in two rows, respectively, between the actuator side guide member and each of the moving block side guide members. Set screws are attached to a moving block.

A linear guide mechanism configured to slidably support a moving block on an actuator, the linear guide mechanism comprising:
- an actuator side guide member attached to the actuator;
- a pair of moving block side guide members attached to the moving block, and disposed on both sides of the actuator side guide member;
- and
- a plurality of balls disposed in two rows, respectively, between the actuator side guide member and each of the moving block side guide members,
- wherein the actuator side guide member includes circulation holes through which the balls circulate,
- the moving block side guide members are made from a heat-treated steel, and
- a pressing mechanism configured to adjust a pre-loading of the balls is attached to the moving block, wherein
- a set screw serves as the pressing mechanism, and
- the set screw is screwed into a screw hole penetrating through a side wall portion of the moving block, and a distal end of the set screw abuts against an outer side surface of the moving block side guide members.
