項第１項記載の根切機の駆動部の給油機構。[Claims for Utility Model Registration] (1) An oil tank is provided inside the base frame of the chain saw body, and an output shaft driven by an engine is protruded from the outside of the base frame and supports the chain. Install the bearing that supports the bar,
In the oil supply mechanism for the drive section of the root cutting machine, the oil tank is in communication with the support bar, and a gear box capable of accommodating a speed reduction mechanism section of a sprocket driven by the output shaft is formed on one side of the support section. A first oil supply passage and a second oil supply passage communicating with the gearbox are connected, a pressure unit is removably attached to the oil fill port of the oil tank, and the oil is supplied with pressure by the pressurization unit.
A lubricating mechanism for a drive unit of a root cutting machine, characterized in that the gear box is lubricated by increasing the pressure inside the tank. (2) The pressurizing unit is made of an elastic material such as rubber, and has an approximately inverted bowl-shaped pressurizing body having an air hole on one side and a bent lower edge on the other side; a substantially annular inner flange component that is removably fitted to the pressurizing body so that the bent lower edge can be crimped; and a short cylindrical member that is located at the back of the inner flange component and is removably attached. , and a rubber breech valve with a tapered end that is removably attached to the inside of one end of the short cylindrical member via a filter material. Lubricating mechanism for the machine's drive unit.
