PURPOSE: To make it possible to pull up one's body effectively without producing a slip by forming a grip which is inclined relatively horizontally or vertically to a slope angle of a staircase.

CONSTITUTION: Rod-shaped hand rails 2 are installed over the whole area of a staircase in the upper part of a side wall 5 of a staircase 1. Grips 3, which comprise rod-shaped members, are installed directly in the upper part of the hand rails 2 in the vertical direction, and what is more, a plurality of grips are installed to comply with the steps of the staircase 1 with a spacing separated from each other. The length of the grips 3 are arranged to be equivalent to the number of steps of the staircase 1 while they are arranged to be located slightly on a rising side from steps 4. This construction makes it possible to reduce power which exerts to leg muscles, and what is more, to be less slippery since the grips are vertical in shape. In addition, as for the spacing between the handrails 2 and the grips 3 it is better to set their dimension so that a human hand may pass through the spacing.
