The invention discloses a rack and pinion steering gear sealing structure which comprises a gear shaft adjusting screw plug (1) and a dust seal (2) matched with the gear shaft adjusting screw plug (1), wherein the dust seal (2) is mounted in the gear shaft adjusting screw plug (1), and is clung to the inner wall of the gear shaft adjusting screw plug (1); a groove (3) is formed in the inner wall of the gear shaft adjusting screw plug (1) and in the position corresponding to the dust seal (2). According to the rack and pinion steering gear sealing structure adopting the structure, through the design of the groove structure at the high-low pressure oil seal part or the dust seal assembling part, when a high-low pressure oil seal and the dust seal are completely assembled in place according to the conventional processing precision requirement and assembly process condition, under a relatively strong axial component force, the groove structure can play a barb role, and the magnitude of interference and the resisting force of sealing part rubber and the coordinated part are increased, so that the problem that the sealing part is divorced from the coordinated part after being used for a long time is solved.
