ABSTRACT:
An elastic shaft joint of the present invention comprises an elastic member, a slide sleeve and a stopper. The elastic member is composed of an elastic material such as rubber, elastomer etc and held on an inner peripheral surface of a cylindrical portion fixedly provided on the cylindrical member. The slide sleeve is made using a low-friction material such as a synthetic resin, an oil-impregnated metal etc, held on an inner peripheral surface of the elastic member and elastically pressed against an outer peripheral surface of the shaft by an elasticity of the elastic member. The stopper is provided between the shaft and the cylindrical member, permits the shaft and the cylindrical member to slightly displace in the axial and rotating directions, and hinders the displacement in the rotating direction beyond a predetermined angle enough to damage the elastic member and the slide sleeve.
