Automobile damper for internally controlling oil leakage

The utility model relates to an automobile damper for internally controlling the oil leakage, which comprises a damper cylinder body, a guide holder, a piston rod and a piston, wherein the guide holder is internally provided with a sliding bearing matched with the piston rod, a ring-shaped working cavity is formed between the axial directions of the guide holder and the sliding bearing, and the ring-shaped working cavity is internally provided with an oil retainer. During the process of resetting movement of the damper of the utility model, the oil retainer can effectively control the oil flow quantity in the ring-shaped gap formed by matching the sliding bearing and the piston rod, can control the oil pressure of an oil seal during the driving with the height (> 0.3m/s), prolongs the service life of the damper, can control the flowing oil in the gas during the driving with the height (less than or equal to 0.1 m/s), reduces the percentage of the flowing quantity of the leaked oil and the normal flowing quant
