Abstract: A driving tool may include a driven member holding mechanism configured to hold the driven member at a driving position inside a driver guide until a driver drives the driven member.

Abstract: An air compressor may include a compressor unit and an external tank unit connectible with the compressor unit. The external tank unit may include an external tank and a battery. The battery may supply electric power to the compressor unit.

Abstract: A magazine in a fastener driving tool includes a magazine body, a pusher, a biasing device and a pusher holding device. The magazine body defines a fastener receiving space for storing a plurality of fasteners therein. The pusher is mounted to the magazine body and is movable in a fastener feeding direction toward a fastener driving channel defined in a tool body of the fastener driving tool. The biasing device biases the pusher in the fastener feeding direction. The pusher holding device can hold the pusher at a midway position within a movable range of the pusher in the fastener feeding direction. The pusher holding device may include no insertion hole or only one insertion hole formed in the magazine body.

Abstract: A pneumatic tool includes a body having a pressure accumulation chamber formed therein for accumulating compressed air. A cap are mounted on the body and has a cap chamber formed therein for communication with the pressure accumulation chamber. The cap has a joint for connection with an air hose from a compressed air source. A gasket is interposed between the pressure accumulation chamber and the cap chamber from each other. The gasket itself forms a valve for preventing a counterflow of the air from the pressure accumulation chamber to the cap chamber, so that exhaust sounds of the air is prevented from being produced when the air hose is disconnected from the joint.
