A restraining structure for a pressure regulator of a paint ball gun includes a cylinder and a restrainer. The cylinder comprises a lower chamber. The lower chamber has an inner wall and an opening. A groove is provided at the inner wall close to the opening to receive the restrainer therein. The restrainer is to confine the movement of a regulating bolt provided in the lower chamber, preventing the regulating bolt from over adjustment to damage other parts.
