The utility model discloses a servo motor photoelectric encoder sheath comprising a cylindrical plastic sheath body with a single closed end and a leading wire hole disposed on the circumference of the cylindrical plastic sheath body. When the servo motor photoelectric encoder sheath is used, a signal leading wire is led out of the leading wire hole from the plastic sheath body, and then the sheath is sleeved from the tail end of a photoelectric encoder. Thus, the sheath is wrapped around the housing of the photoelectric encoder and closes an exposed gap and an opening so as to achieve a dustproof and moisture-proof effect. An annular stopping edge is disposed on the opening end of the plastic sheath body so as to be wrapped around the circumferential edge of the head portion of the photoelectric encoder for achieving a better sealing effect. An annular seam allowance step is also applied to the inner side of the annular stopping edge such that the plastic sheath body and the housing of the photoelectric enco
