Abstract
An output shaft lubricating structure of a liquid pressurizing pump is provided. A first eccentric portion of an output shaft acts as the maximum stress for load when the liquid is pressurized and works. By the power of the output shaft, a telescopic piston of an oil supply device is directly pushed by a second eccentric portion to draw the lubricating oil in a circular core hole and to pressurize and supply the lubricating oil to an oil supply hole of the output shaft to force an oil outlet hole to drain the lubricating oil to the surface of the first eccentric portion for circulatory supplement, such that the turning of a turning wheel on the first eccentric portion can keep better lubrication for a long time so as to prolong the service life of the output shaft and the turning wheel.
