ABSTRACT:
An improved shaft for mounting an article such as a core for roll paper is proposed. The shaft has a core shaft, a boss mounted on the core shaft, and a plurality of sliders mounted in axial grooves formed in the boss. The sliders are slidable axially to a position at which their outer edges extend above the boss surface and are pressed against the inner wall of the center hole of the article to be mounted to securely hold the article.
