PURPOSE: A crutch which has flexibility is provided to prevent 'a damage which is caused by a hole of rubber' by adding a metal plate to a lower end part of an aluminum tube support stand and prevent an injury of a user by widening a contact area and minimizing a slip by a folding of rubber which is caused by a gap around the rubber in case of using the crutch on the floor which is comprised of a slippery material. CONSTITUTION: A crutch which has flexibility comprises an armpit pad which supports an armpit; a pair of supports which are installed in the lower both sides of the pad; and an aluminum tube support stand (20) which is installed in order to adjust height between the support stands; and a rubber (10) which contacts with the floor in the lower end part of the aluminum tube support stand. The crutch prevents a hole of rubber by adding a metal plate (30) to the lower end part of the aluminum tube support stand which contacts with the rubber, is safely used without a slip by forming several gaps around the outer periphery of the rubber and widening an area which contacts with the rubber on the floor, and minimizes 'a shock which comes to a user from the rubber which becomes flexible by having a gap' when using the crutch. |
