The utility model discloses a lubricating oil sealing structure of a gear motor. The lubricating oil sealing structure comprises a motor front end cover. A bearing and a sealing ring sleeved on a motor output shaft and matched with the motor output shaft closely are arranged on the motor front end cover. The lubricating oil sealing structure of the gear motor is characterized in that an oil retaining ring is sleeved on the motor output shaft and arranged on one side of the sealing ring facing a reduction gearbox. By arranging the oil retaining ring in front of the sealing ring, when the gear motor is operated and lubricating oil flows to the sealing ring, the high-pressure lubricating oil in the reduction gearbox is first retained by the oil retaining ring and then bent through 180 degrees at the outer edge of the oil retaining ring to flow back to the sealing ring. At this time, pressure of the lubricating oil is greatly reduced, pressure of the lubricating oil on the sealing ring is greatly reduced, and a s
