Abstract
A driving tool is provided with first and second grease reservoirs for supplying grease to seal rings present on the outer and inner peripheral circumferences of a head valve in contact with a spring guide. Because of this configuration, wearing off of resistance of the seal rings due to gradual loss of grease can be improved and air leakage therefrom can also be prevented, which can improve durability of the driving tool.
