The friction apply unitincludes a unit main body, a brake member, an oil pressure cylinderand a plate spring. The brake memberis disposed so as to face the side surfaceof the guide railand can be contacted with the other portions of the side surfacethan the rolling body rolling groovethereof. The oil pressure cylinderincludes a piston memberwhich is structured to be driven in a positive direction to thereby press the brake memberagainst the side surfaceof the guide railand also the piston membercan be driven in the opposite direction to thereby remove the pressure of the brake memberfrom the side surface
