用エキスパンダ。 The tip of the movable shaft, which is inserted through the base and supported so as to be able to move forward and backward in the axial direction, has a taper center having a tapered surface formed so that the cross-sectional area of the movable shaft gradually decreases in the direction of movement of the movable shaft. A plurality of driven members arranged around the axis of the movable shaft while being in elastic contact with the tapered surface are attached to the base concentrically, and each driven member is attached to the base in a direction substantially perpendicular to the axis. 1. An expander for a seal ring, which is movably attached, and each of the driven members is formed with an arm portion inscribed in the seal ring in order to push and expand the seal ring in a plurality of directions.
