ABSTRACT:
The present invention relates to a ground surface slide guide having a resin body made of synthetic resin, and a metal hub integrally coupled to the resin body to rotate together. The resin body is composed of a tubular body and a flange extending upward to the outside from the entire periphery of the lower end of the tubular body and covering the lower surface of the rotary blade. A blade retaining ring pressed against the lower surface of the rotary blade is formed on the outer periphery of the hub, and the blade retaining ring is exposed to the upper end surface of the tubular body. The hub is attached to a drive shaft by a fastener, and the rotary blade is clamped between a blade rest and a blade retaining ring. The lower end of the tubular body serves as a ground contact surface.
