Oil filling structure of pneumatic tool, including an airflow way formed in the main body for conducting high pressure air into a pneumatic cylinder disposed in the pneumatic tool. An air intake switch is connected with the airflow way for controlling opening/closing of the airflow way. An oil filling hole is disposed in air intake switch. When the switch is positioned in a close position, a lubricant can be filled into the oil filling hole to flow into the airflow way. The high pressure air can entrain the lubricant in the airflow way into the cylinder to lubricate and clean the cylinder.
