PROBLEM TO BE SOLVED: To provide a rack shaft for a steering device in which a first member having a first rack tooth, a second member having a second rack tooth and an intermediate member arranged between the first member and the second member can be jointed to one another without frictionally welding the members while keeping a relative angle between the first rack tooth and the second rack tooth at a predetermined angle, and a manufacturing method for the same.SOLUTION: A rack shaft 2 comprises: a first rack shaft 3 having a first rack tooth 3a to which is transmitted steering force of a steering wheel; a second rack shaft 4 having a second rack tooth 4a to which is transmitted steering assisting force; and an intermediate member 5, arranged between the first rack shaft 3 and the second rack shaft 4, which has at one end side thereof a first screw shaft 52 to be screwed to the second rack shaft 4 and has at the other end side a second screw shaft 53 to be screwed to the second rack shaft 4. The first screw part 52 and the second screw part 53 have a reverse thread relation.SELECTED DRAWING: Figure 1
【課題】第１のラック歯を有する第１部材と、第２のラック歯を有する第２部材と、第１部材と第２部材との間に配置される中間部材とを、第１のラック歯と第２のラック歯との相対角度を所定の角度に保ちつつ、各部材を摩擦圧接することなく互いに結合可能としたステアリング装置用のラックシャフト及びその製造方法を提供する。【解決手段】ラックシャフト２は、ステアリングホイールの操舵力が伝達される第１のラック歯３ａを有する第１のラックシャフト３と、操舵補助力が伝達される第２のラック歯４ａを有する第２のラックシャフト４と、第１のラックシャフト３と第２のラックシャフト４との間に配置され、第２のラックシャフト４にねじ結合する第１のねじ軸５２を一端側に有し、かつ第２のラックシャフト４にねじ結合する第２のねじ軸５３を他端側に有する中間部材５とを備える。第１のねじ部５２と第２のねじ部５３とは、互いに逆ねじの関係にある。【選択図】図１
