Abstract

The present invention relates to an apparatus for preventing a clearance of a rod of a breaker, wherein a retainer that is brought into contact with the rod of the breaker when the rod moves upwards and downwards is arranged to easily retain the left and right movement of the rod caused when the rod strikes an object, to achieve prevention in advance against breakage of the lower stepped portion of a breaker housing, reduce the vibration and noise of the breaker, and prevent the ingress of dust or the like into the breaker housing, thereby lengthening the lifespan of the breaker.
