Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a deflector type ball screw and its assembling method in which deflectors fitted in a nut screw are firmly fixed after a rotor shaft is assembled, and thereby backlash entirely does not occur. SOLUTION: In a deflector type ball screw in which a nut screw 21 is screwed onto a screw shaft 4 through steel balls 25, and the steel balls 23 are circulated by deflectors 22 loaded in the nut screw 21, a cylindrical rotor shaft 11 is screwed on the outside periphery of the cylindrical nut screw 21, and thereby projections 22d provided on the outside surfaces of the deflectors 22 abut against the inside peripheral surface of the rotor shaft 11.
