Abstract:
PURPOSE: To provide effectiveness of anti-skid performance of the grounding parts of crutches, a sole, a tire, etc., under both road conditions of snow fall and freezing or a naked road surface without snow cover.

The height of the spike pin shaped hard rubber parts 1 is set to be same as the surface of the soft rubber part 2 or lower than the surface of the soft rubber part 2 so that damping resistance is produced between the surface of the spike pin shaped hard rubber and a road surface during pressurising or compressing.
