摘要： A central column (3) is formed by an upper column member (8) and a lower column member (9). An inner periphery of the upper column member (8) is irregularly formed, and a circumferential aligning joint (22) matching the irregular form of the inner periphery is provided on the lower column member (9). When stopper projections (19) for engaging with keys formed on a body (1) are disengaged from the upper column member (8) and the lower column member (9), an engagement (15) of a nut (14) adapted to be threaded onto a threaded rod (28) causes the stopper projections to object from through holes (18) in key grooves (11), and when the lower column member (9) is connected to the upper column member (8), elastic rods (17) permit the stopper projections to withdraw. Disengagement of the lower column member (9) from the upper column member (8) reduces an extent of projection of the upper column member (8) in a downward direction for adaptation to low angle. Rack teeth (5) can be easily positioned upon connection of the lower column member (9), and the stopper projections (19) for preventing slipping-off of the upper column member (8) project upon disengagement of the lower column member (9) whereby manipulation is improved.

摘要： Rotary cutting blades (20) for cutting and forming rack teeth (2) in a rack forming surface (16) of a tubular body (11) are disposed in parallel with each other along a longitudinal direction of the tubular body (11). A direction parallel with the rotary cutting blades (20) and the longitudinal direction of the tubular body (11) are maintained in parallel with each other. A number of rack teeth (2) are cut and formed simultaneously in the rack forming surface (16) of the tubular body (11) by means of the respective rotary cutting blades (20). At this time, central positions of root portions (2a) of the rack teeth formed in the rack forming surface (16) of the tubular body (11) are cut by means of a rotart cutting blade (22) at the same time when the rack teeth (2) are cut and formed. The phases of the rack teeth (2) of the tubular body (11) which is divided into two positively coincide with each other even in such a divided state to thereby maintain the strength of the rack teeth (2), thus eliminating a risk of the teeth being broken.
摘要翻译：在管状体（11）的齿条形成表面（16）中切割和形成齿条齿（2）的旋转切割刀片（20）沿着管状体（11）的纵向方向彼此平行地设置。与旋转切割刀片（20）平行的方向和管状体（11）的纵向保持彼此平行。多个齿条齿（2）通过相应的旋转切割刀片（20）同时切割并形成在管状体（11）的齿条形成表面（16）中。此时，形成在管状体（11）的齿条形成表面（16）中的齿条的根部（2a）的中心位置在旋转切割刀片（22）的同时被切割齿条齿（2）被切割并形成。管状体（11）的齿条齿（2）的相位即使在这样的分割状态下被分成两个也相互重合，从而保持齿条齿（2）的强度，从而消除了牙齿被打破了。
