In a crutch usually used by the disabled, an inverse conical resilient support member (1) is provided at the lower end of the crutch (2). The support member made of rubber-like material is provided with an upper threaded hole (3) for engaging the leg member (2a) of the crutch, and with a lower tapered recess (7) therein for nesting a pinned circular plate (8). The pinned circular plate has a plurality of downwardly pointed pins (8a) which serve to stick into the ground or the like in rainy or snowy day under the weight of the user. Thus, the user will not slip and fall on wet or icy roads. |
