description A swing filter (10), an illumination device (1) for an endoscope, and a medical endoscope. The swing filter (10) comprises: a limiting base (11), which is provided with an optical window (1101) and a limiting portion (1102); a swing assembly (12), which is provided with a light transmitting portion (1201) and a light filtering portion (1202) both arranged around a swing axis (120); and a driving mechanism (13), which is drivably connected to the swing assembly (12). The swing assembly (12) is swingably arranged on the limiting base (11), and the gravity center (O) of the swing assembly (12) deviates from the swing axis (120) of the swing assembly (12). When the driving mechanism (13) drives the swing assembly (12) to rotate positively, the swing assembly (12) abuts against the limiting portion (1102) positively under the action of the gravity of the swing assembly, such that the light transmitting portion (1201) is kept aligned with the optical window (1101). When the driving mechanism (13) drives the swing a
