Provided is a rack guide capable of achieving both stable supply of lubricant from a rack bar to a lubricant holding groove and stable supply of lubricant from the lubricant holding groove to the rack bar when the rack bar slides relative to the rack guide. At least one pair of lubricant holding grooves (122), which hold a lubricant (G) interposed between the rack bar (SD3) and the support surface (120A) and face each other in the longitudinal direction of the base, are disposed on the support surface (120A) so as to extend in the longitudinal direction of the base, which is orthogonal to the longitudinal direction of the base, and so as to protrude away from each other in the longitudinal direction of the base. The apex (122B1) of the lubricant holding groove (122) in the longitudinal direction of the base is disposed in the contact region (120A1).
提供一种在齿条杆相对于齿条导承滑动时能够同时实现从齿条杆向润滑剂保持槽的润滑剂的稳定的补给和从润滑剂保持槽向齿条杆的润滑剂的稳定的供给的齿条导承。对介于齿条杆(SD3)和支承面(120A)之间的润滑剂(G)进行保持并在底座长度方向上对置的至少一对润滑剂保持槽(122)在支承面(120A)上以沿着与底座长度方向正交的底座短边方向延伸并在底座长度方向上彼此远离地膨出的形状配设,润滑剂保持槽(122)的底座长度方向的顶点(122B1)配置在接触区域(120A1)。
