ベーン型揺動モータのシール機構。A sealing mechanism for a vane-type swing motor, wherein the vane-type swing motor includes a split casing, a vane shaft installed in the casing, and a vane fixed on the vane shaft. , a stopper mounted inside the casing to set a rotation range of the penin, the casing having a split mating surface parallel to a plane intersecting the axis of the vane shaft, The sealing mechanism includes a stopper seal that is attached to the stopper and seals between the stopper and the vane shaft and between the stopper and the inner surface of the casing, and the stopper seal is annular and close to the shaft of the vane shaft. In a sealing mechanism for a vane-type rocking motor, the sealing mechanism is fitted into an annular groove formed on the outer circumferential surface of the stopper along a core wire to form a partition inside the casing, wherein , at least one of a convex portion and a concave portion is formed in a portion parallel to the axial center line of the vane shaft portion, and a concave portion and a convex portion that fit into the convex portion and the concave portion (both of which are attached to the stopper seal); A sealing mechanism for a vane-type swing motor, characterized by the following:
