ABSTRACT:
A rotary brush floor polisher is provided with an upper and a lower disk member movably connected with each other through a shock absorbing member interposed therebetween, on which lower disk member is fixedly mounted a polishing brush or pad which is rotatably driven by an electric motor to glide over a floor to polish and clean the same. The polisher is characterized by the shock absorbing member each of which is interposed: between the upper and the lower disk member; and between the electric motor and a platform on which the motor is mounted. The shock absorbing member has a simple and compact construction which: realizes reduction in size of the polisher; reduces vibrations and noise in operation; and eliminates a fear that the operator's fingers and like objects are sandwiched between the upper and the lower disk member by mistake in operation to ensure a safety operation of the polisher.
