Abstract: A pneumatic tool includes a drive part configured to be driven by compressed air, a control valve configured to switch the presence or absence of operation of the drive part, an on-off valve part configured to switch the presence or absence of operation of the control valve, and a timer part configured to control the operation of the on-off valve part and switch the presence or absence of operation of the control valve after a lapse of a predetermined time. The timer part comprises a timer piston configured to move in one direction, and a timer piston cylinder configured to support the timer piston. The pneumatic tool comprises a throttle part configured to throttle the flow rate of air flowing into or flowing out from the timer piston cylinder, and an adjustment part configured to adjust an operating time of the timer piston.

Abstract: A handheld tool includes a nose portion having an injection passage for a fastener, a magazine accommodating the fastener and located in a direction intersecting with the injection passage, a magazine cap portion opening and closing the magazine by a tip portion rotating in a direction separating from and approaching the magazine with a base end portion as a fulcrum, and a door portion rotatably coupled to the tip portion via a coupling shaft. The nose portion includes an engaging portion engageable with the door portion. The door portion is configured to, in a state where the magazine cap portion is opened, bent toward the magazine with the coupling shaft as a fulcrum, and in a state where the magazine cap portion is closed, extend linearly and engage with the engaging portion.

Abstract: An air duster structure that is configured to jet compressed air out of a nozzle, includes a flow amount adjustment mechanism which is configured to adjust an amount of air jetted out of the nozzle. The flow amount adjustment mechanism includes: a pipe line for circulating air; a valve member disposed inside the pipe line and being movable; and a throttle portion configured to gradually change an area of a flow channel in which air circulates, with a movement of the valve member, to control a flow amount of the air in the pipe line. The throttle portion is structured so as to increase the area of the flow channel at an accelerated rate when the valve member moves in a direction that opens the pipe line.

Abstract: A screw driving machine includes a driving piston to which a driver bit is attachable, a driving cylinder partitioned into a first chamber and a second chamber by the driving piston and moving the driver bit when compressed air is supplied to the second chamber, an air motor rotating the driver bit by the compressed air, an air flow path communicating the second chamber and the air motor, a main chamber storing the compressed air and communicating with the air flow path, and a main valve opening and closing communication between the air flow path and the main chamber. The driving cylinder has a supply port communicating the air flow path and the second chamber. A throttle portion is disposed to be displaceable on an outer periphery of the driving cylinder to change an opening area of the supply port.

Abstract: A handheld tool includes a magazine accommodating a plurality of fasteners coupled by a coupling band, a lid portion opening and closing the magazine, a nose portion having an injection passage and an injection port, a supply passage connecting the injection passage and the magazine for feeding the fasteners coupled by the coupling band to the injection passage; and a driver bit separating the fasteners of the injection passage from the coupling band and driving the fasteners toward the injection port. The nose portion has a discharge port for discharging the coupling band from which the fasteners are separated. The injection passage and the discharge port have an opening portion on a lateral side perpendicular to the extending direction of the injection passage, and the lid portion exposes and covers the opening portion.
