A beverage extracting apparatus for vending machines includes a cylinder for storing a liquid mixture of water and raw material of a beverage, a valve opening and closing the inflow port of the cylinder, a filter covering the bottom opening of the cylinder, a filter support vertically moved to open and close the bottom opening of the cylinder via the filter, an air pressure supply for supplying pressurized air into the cylinder to forcibly filtrate the liquid mixture stored in the cylinder via the filter, a filter support guide frame vertically guiding the filter support, a filter support drive for vertically moving the filter support and including a lever pivotably supported by the filter support guide frame and engaged with the filter support, and an adjusting device for adjusting the vertical position of the filter support guide frame. The pressing force of the filter support onto the bottom of the cylinder can be easily adjusted to an adequate force by adjusting the vertical position of the filter support guide frame by the adjusting device. High accuracy of the parts for the filter support driving mechanism is not particularly required, thereby making the processing of the parts for the mechanism easy and reducing the cost for manufacturing the apparatus.
