PROBLEM TO BE SOLVED: To provide a safety implement to prevent the occurrence of an accident wherein a large caster (a wheel shape with size of approximate 100 mm or more) runs over the foot of a worker at a factory and an office and facilitate exchange and after-mounting and have simple structure. SOLUTION: A collar 2 is inserted in the core of a roller 1 formed of an elastic substance and by inserting a roller support 3 through the core, the roller support 3 is bent on the two end sides of the collar 2, and further an object having two terminals being bent is mounted on a caster for use. Thus, an auxiliary safety implement has simple structure that the number of parts is only three. Mounting and demounting thereof on and from the caster are simplified such that with the two terminals of the roller support 3 held by a hand, opening is effected for mounting and demounting, and the function of the caster is protected from damage.
