Abstract: A driving tool includes a driver, and a piston connected to the driver. The piston and the driver are housed within a cylinder such that the piston slidably moves within the cylinder by gas active pressure. The cylinder is positioned in an adjoining arear of an axis line of the piston. The cylinder is made of iron. Accordingly, a weight in the adjoining arear of the axis line of the piston is more than a cylinder made of aluminum or resin. Because of the large weight in the adjoining area of the axis line of the piston, a reaction force against a movement of the piston and a driving of the driver can be effectively restrained.
