Abstract: A driving tool includes a flywheel, a driver held to be movable between an initial position and a driving position along an movement axis, a ring member configured to transmit rotational energy of the flywheel to the driver, and a driver moving mechanism configured to move the driver with respect to the ring member from the initial position to a transmitting position. When the driver is placed in the initial position, the ring member is disposed loosely around the outer periphery of the flywheel. When the driver is moved to the transmitting position by the driver moving mechanism, the ring member is frictionally engaged with the driver and with the flywheel, rotated by the flywheel, and transmits the rotational energy to the driver, thereby pushing the driver from the transmitting position toward the driving position.

Abstract: In a driving tool, during and/or after a driving operation has been completed, a restriction member is retained in an on-position by a cam. An energizing switch is retained in an on-state by an actuation portion of the restriction member. Because of this configuration, if a trigger is released during and/or after the driving operation has been completed, an electric motor continues to be activated, which causes a driver to return to a standby position.

Abstract: A driving tool includes a tool body, a flywheel, a driver and a pressing mechanism. The pressing mechanism is disposed on a side opposite to the flywheel across the driver in a facing direction in which the flywheel and the driver face each other. The pressing mechanism includes a spring mechanism and a pressing roller. The spring mechanism includes a first spring part and a second spring part and is configured to be displaced along with forward movement of the driver. The pressing roller is configured to press the driver toward the flywheel in the facing direction by a biasing force of the spring mechanism in a process of the forward movement of the driver, to thereby enable transmission of the rotational energy to the driver. A spring constant of the whole spring mechanism varies according to an amount of displacement of the whole spring mechanism.

Abstract: A driving tool includes a tool body, a flywheel, a driver, a pressing mechanism and a return mechanism. The pressing mechanism includes a first biasing part and at least one roller. The at least one roller is supported to be rotatable around a second rotation axis extending in parallel to a first rotation axis of the flywheel and to be movable in an extending direction of the second rotation axis. The pressing mechanism is configured such that a position of the at least one roller relative to the driver changes in the extending direction of the second rotation axis between a nail-driving process and a return process, thereby making the at least one roller to be incapable of pressing the driver in the return process.A nailing machine includes a tool body, a flywheel (40), a driver (3), a pressing mechanism and a return mechanism. The pressing mechanism includes a spring mechanism and a pressing roller (87). The pressing roller (87) is supported to be rotatable around a rotation axis (A2) and movable in a left-right direction, and configured to press the driver (3) toward the flywheel (40) by a biasing force of the spring mechanism in a nail-driving process in which the driver (3) moves from an initial position to a nail-driving position, to thereby enable transmission of the rotational energy to the driver (3). The pressing mechanism is configured such that the position of the pressing roller (87) relative to the driver (3) changes in the left-right direction between the nail-driving process and a return process, thereby making it impossible for the pressing roller (87) to press the driver (3) in the return process.

Abstract: A driving tool has a nose portion in which a driving channel is formed. A contact arm is movably provided at an end of the nose portion. The contact arm moves between an OFF position and an ON position. A driver strikes a driven member set in the driving channel. A shutter moves between a blocked position located on a travel path of the driver, and an open position retracted from the travel path to allow the driver to move. A connecting rod connects the contact arm and the nose portion. The connecting rod allows the shutter to move from the open position to the blocked position in response to a movement of the contact arm from the ON position to the OFF position.

Abstract: A driving tool includes a feeder that successively loads a driving member to a loading position. A driver moves downward in a driving direction to drive the driving member loaded to the loading position. A plurality of driving members are combined in parallel by a flexible member. A lifter engages the driver to move the driver upward in a direction opposite to the driving direction. A position detection sensor detects a rotation position of the lifter to detect a position of the driver. A controller determines that a tip end of the driver is positioned above the loading position according to a signal from the position detection sensor. The controller loads the driving member via the feeder.

Abstract: A gas-spring type driving tool with a charge valve, a relief valve, and an opening valve provided in an accumulation chamber. Compressed gas can be quickly charged into the accumulation chamber by connecting the charge valve to an external device. The relief valve maintains the accumulation chamber at a preset pressure. The opening valve is capable of opening the accumulation chamber quickly to the atmosphere. This allows for a quick removal of a jammed nail from a driving nose.

Abstract: A driving tool includes a motor, a flywheel, a driver and a control part. The driver is disposed to face an outer periphery of the flywheel and configured to perform a driving operation of driving the fastener into the workpiece by moving along an operation line, by rotational energy transmitted from the flywheel. The control part is configured to control driving of the motor. The control part is configured to set rotation speed of the motor based on first information and second information. The first information corresponds to rotational energy of the flywheel before the driving operation of the driver. The second information corresponds to rotational energy of the flywheel after the driving operation of the driver.

Abstract: A driving tool includes a driver, a first moving mechanism and a second moving mechanism. The driver is held to be linearly movable between an initial position and a driving position along a working axis. The first moving mechanism is configured to move the driver from the initial position to the driving position so as to cause the driver to drive a fastener. The second moving mechanism is configured to return the driver from the driving position to the initial position. The second moving mechanism includes an elastic member configured to generate an elastic force according to torsional moment acting around an axis of the elastic member. The elastic member is configured to return the driver to the initial position by the elastic force generated when the torsional moment acts on the elastic member in interlock with a movement of the driver to the driving position.
