PURPOSE: To provide a stopping fixture usable in an approximate sized stop hole of round shape and angular shape with reduction of a cost attainable.

CONSTITUTION: In a stopping fixture, a flat sectional shape of a shaft part is formed of aligning surfaces 12, 12 relating to a stop hole C, aligning planes 13, 13 connected to the aligning surfaces 12, 12 to relate to a stop hole S, planes 14, 14 connected to the aligning planes 13, 13 to provide a plurality of elastic fins 21 and connection surfaces 15, 15 connected to the planes 14, 14 and to the aligning surfaces 12, 12, so as to prevent protruding from each stop hole C, S. Further, a plurality of the elastic fins 21 are crossed at 45° with the aligning planes 13, 13, to raise the fin from the planes 14, 14, and a point end of a plurality of the elastic fins 21 is protruded to outside each stop hole C, S, to multistep provide the fin.
