A wear prevention device of a shoe heel is provided to minimize impact transmitted to the heel by bringing preventing balls with good wear resistance into contact with the ground and absorbing impact with an elastic spring. In the wear prevention device(100) of a shoe heel(111), a shoe joining part is composed of the shoe heel of predetermined height having an attaching face formed at the upper side and attached to the lower side of the shoe and a bottom face(113) formed at the lower side to come into contact with the bottom; plural mounting through-holes(114) formed at the side of the shoe heel; and an anti-separation sill disposed at the lower side of the mounting through-hole, wherein the diameter of the anti-separation sill is gradually reduced towards the bottom face. A preventing unit comprises a spherical preventing ball(125) formed in a preventing housing(121) having a preventing ball settling part(122), inserted into the mounting through-hole of the shoe joining part and placed at the anti-separation sill; an elastic spring(126) installed into the preventing housing to elastically support the upper side of the preventing ball; and a joining part(123) formed at the upper end of the preventing housing to join a combining piece(124). Therefore, wear of the shoe heel is minimized by supporting the preventing balls with elastic force of the elastic spring. |
