ABSTRACT:
A pointer bushing for securing an indicating element to an output shaft of an indicating instrument includes a base for spacing the pointer above the instrument face, a collar for connecting the base to the indicating element, and an S-shaped shaft gripping section for connecting the base to the output shaft. The output shaft connection includes a pair of posts which depend axially from the base, a reversely bent wing which extends from each arm, and a shaft gripping member forming the end of wing, the gripping members being in confronting relation to form a generally cylindrical, axially extending, radially expansible, socket for gripping the shaft whereby to fixedly hold the output shaft against relative rotative as well as axial movement.
