Abstract
A finishing orbital sander ( ) includes a main body ( ) and a base ( ) provided below the main body. Provided between the main body and the base are a plurality of foot assemblies ( ). Each assembly in turn includes a cylindrical or columnar foot ( ) made of aluminum and a pair of rubber O-rings ( ) at both ends of the cylindrical foot. Each foot additionally includes reduced diameter sections ( ) at both ends, where the O-rings are disposed. The reduced diameter sections ( ) are fitted in the O-rings and placed in recessed seats ( ) provided in opposing surfaces of the main body ( ) and the base ( ), thus elastically supporting the aluminum feet ( ) in the axial direction thereof. The axial dimension of each reduced diameter section ( ) is made no longer than the thickness (i.e., the axial dimension) of the O-ring ( ), so that the tip end of the reduced diameter section does not exceed or project from the axial outermost end of the O-ring. The foot assemblies ( ) can effectively counteract vibration occurring in the axial direction of the feet ( ) and reduce vertical vibration of the base ( ) while facilitating a smooth orbital motion of the base.
