The invention discloses a slipping mechanism for a mirror surface driver of an automotive rearview mirror. The slipping mechanism comprises a rotation shaft (5), a straight-tooth wheel column (2) and an oblique-tooth disc (1) which sequentially sleeves the rotation shaft (5), as well as a limiting mechanism arranged on the rotation shaft (5) and used for limiting axial movement between the straight-tooth wheel column (2) and the oblique-tooth disc (1). The slipping mechanism is characterized in that a driving friction surface is arranged on the oblique-tooth disc (1); a driven friction surface matched with the driving friction surface is arranged on the straight-tooth wheel column (2); a friction force used for driving linkage of the straight-tooth wheel column (2) and the oblique-tooth disc (1) is formed between the driving friction surface and the driven friction surface; the maximum value of the friction force is smaller than the resistance generated by rotating the straight-tooth wheel column (2) to an extreme position. The slipping mechanism for the mirror surface driver of the automotive rearview mirror is simple in structure and can be used for effectively preventing the mirror surface from being broken by rotating out of travel when the mirror surface rotates to the extreme position.
