The rack section (21) has a cured layer (26) over the entire circumference in a radially outer portion including the rack teeth (20). The depth (tb) of a portion of the cured layer (26) that is located on the opposite side of the rack teeth (20) in the radial direction is shallower than the depth (ts) of portions of the cured layer (26) that are located on both sides of the rack teeth (20) in the tooth width direction.

    齿条部(21)在包含齿条齿(20)的径向外侧部分遍及整周地具有固化层(26)。固化层(26)中的存在于在径向上与齿条齿(20)相反的一侧的部分的深度(tb)比固化层(26)中存在于齿条齿(20)的齿宽方向上的两侧的部分的深度(ts)浅。
