Zusammenfassung:	Provided is a dust stop device (14) for a sealed kneader (1), the device being capable of excellent supply of lubricating oil. The sealed kneader (1) includes a pair of rotors (4) and a supporting member (3, 9A, 9B). The dust stop device (14) includes a rotating ring (15) attached to each rotor (4) and a stationary ring (16) attached to the supporting member (3, 9A, 9B). Both the rings (15, 16) have respective contact surfaces which make surface contact with each other. The stationary ring (16) has a lubricating-oil supply portion (20) with a through-hole. A part of the through-hole, the part including a part opened in the contact surface, is a long hole extending along a circumferential direction of rotation of the rotating ring (15).
