摘要： The present invention addresses the problem of providing a sealed structure that includes a sealing ring and that can prevent occurrence of a gap between the inner surface of a shaft hole and the outer circumferential surface of the sealing ring. Said problem is solved by a sealed structure comprising: a shaft; a member having a shaft hole in which the shaft is to be inserted; and a sealing ring for sealing a gap between the outer surface of the shaft and the inner surface of the member. The sealed structure is characterized in that: the shaft has, in the outer surface thereof, a groove in the shape of a circular ring in which the central axis line of the shaft is located at the center; the bottom surface of the groove has a recess; the sealing ring has a protrusion that protrudes from the inner circumferential surface thereof toward the central axis line of the shaft; when the sealing ring is placed inside the groove, the protrusion fits into the recess; when the shaft is rotated, an end face X in the circumferential direction of the protrusion and an end face Y in the circumferential direction of the recess are brought into contact with each other, so that the sealing ring is pushed radially outward; the end faces X and Y are both represented as a straight line; and an angle α of the straight line representing the end face X with respect to the radial direction of the sealing ring and an angle δ of the straight line representing the end face Y with respect to the radial direction of the shaft are both at least 45 degrees.

摘要： Generation of a space between an inner peripheral surface of a shaft hole and an outer peripheral surface of a seal ring is suppressed. A sealing structure (1) is a sealing device to seal an annular space between a shaft (50) and a shaft hole (61) into which the shaft (50) is inserted. The sealing structure (1) includes an annular seal ring (2) around an axis line x attached to a groove (51) of the shaft (50), and a locked portion (3) formed on a bottom surface (52) of the groove (51) of the shaft (50). The seal ring (2) has a locking portion (4) formed on an inner peripheral surface (21). The locking portion (4) and the locked portion (3) are formed so as to be lockable with each other and formed such that the seal ring (2) is pressed toward an outer periphery side when the locking portion (4) and the locked portion (3) are locked with each other.

摘要： Eine Dichtungsanordnung (200) zum Abdichten eines Innenraums (116) zwischen einem Lagergehäuse (115) und einer drehbaren Welle (109) gegenüber einer Umgebung:
- einen an dem Lagergehäuse (115) befestigbaren Dichtungskörper (203, 204) mit einem ersten Ende (205) und einem zweiten Ende (206), wobei der Dichtungskörper (203, 204) entlang einer Haupterstreckungsrichtung (207) länglich ausgedehnt ist und ausgebildet ist, in einem montierten Zustand ringförmig um die drehbare Welle (109) angeordnet zu sein, sodass das erste Ende (205) und das zweite Ende (206) eine gemeinsame Stoßstelle (209) aufweisen,
- einen vorspringenden Bereich (210), der an dem ersten Ende (205) des Dichtungskörpers (203, 204) angeordnet ist und tangential zur drehbaren Welle (109) in Richtung einer vorgegebenen Hauptdrehrichtung (113) der drehbaren Welle (109) vorspringt, sodass der vorspringende Bereich (210) über den Dichtungskörper (203, 204) übersteht und die Stoßstelle (209) auf einer dem Innenraum (116) zugewandten Seite überlappt.
