Abstract: In order to make it possible to easily carry out filling up of a compressed air to a compression chamber without making a fastener driving machine larger in size, there is provided a fastener driving machine that includes a cylinder that forms a piston chamber defined by a piston and drives a driver blade by the piston. The housing has a cylinder case part for housing a cylinder, and a handle part. A pressure accumulating container is provided on the cylinder. The pressure accumulating container includes a bottom wall portion and a top wall portion. A compression chamber that communicates with the piston chamber is provided therein.

Abstract: In order to provide a driving machine which achieves reciprocating movements of a rack using a simple mechanism and is able to smoothly engage and disengage the rack by reducing the friction during engagement and disengagement of the rack, the driving machine is equipped with: a nose that extends in a prescribed direction; a housing that has the nose; a blade that has an engaging section, is movably guided in the housing in the prescribed direction, and is capable of driving a fastener via the nose; and a transmission mechanism that has an engaged section for engaging with the engaging section in order to transmit a driving force, wherein the transmission mechanism has a roller mechanism for guiding the engaging section and engaged section to disengage from each other.

Abstract: A driving machine capable of performing replenishment of air in a pneumatic chamber includes: a housing; a cylinder provided within the housing; a pneumatic chamber spatially connected to the cylinder; a piston reciprocally movably provided in the cylinder; a blade attached to the piston and striking a stopper; and a moving mechanism reducing an internal volume of either the pneumatic chamber or the cylinder by a motor, and the driving machine drives the stopper by repulsive force of compressed air. The driving machine has a pressure accumulating mode in which the pneumatic chamber is pressurized by the motor from a state where the pneumatic chamber communicates with outside, and a striking mode in which the piston is moved by the motor from a bottom dead point to a top dead point in the cylinder and then from the top dead point toward the bottom dead point, thereby driving the stopper.
