ABSTRACT:
A wiper 14 is arranged at a position so as to press to both a side surface 2M of a water fountain roller 2 and a side surface 3M of a metering roller 3. The dampening solution 10 adhered on the side surface 2M and 3M can be scraped off from the side surfaces by the wiper 14. Further, surplus dampening solution 10 stored in a groove 5 formed between the rollers is guided into a water fountain 4. The wiper 14 is made of an elastic body having water retention. So that, lubrication is expected when the dampening solution 10 is absorbed in the wiper 14. Other grooves are formed on the wiper 14 along with edges of a bracket 27 and a bracket 28.
