Abstract: A rebar tying tool may include a holder, a stopper, a driving roller, and a driven roller. The stopper may be configured to switch between a prohibiting state in which the stopper prohibits a reel from detaching from the holder and an allowing state in which the stopper allows the reel to detach from the holder. The driving roller may be configured to rotate. The driven roller may be configured to switch between a clamped state and a non-clamped state, the wire may be clamped between the driving roller and the driven roller when the driven roller is in the clamped state, and the wire may not be clamped between the driving roller and the driven roller when the driven roller is in the non-clamped state. The driven roller may be in the non-clamped state at all times while the stopper is in the allowing state.

Abstract: A tying machine disclosed herein includes a feed mechanism. The feed mechanism includes a feed roller that feeds a tying string; a feed motor that rotates the feed roller; a cover disposed between the feed roller and the feed motor, and including a through hole; and a suppression member that suppresses movement of dust from a feed roller side to a feed motor side via the through hole. Another tying machine disclosed herein includes a reel on which a tying string is wound; a brake member that engages with the reel to brake the reel; and an actuator that drives the brake member. The brake member is interposed between the reel and the actuator. Yet another tying machine disclosed herein includes a housing; a reel on which a tying string is wound; a magnet that rotates integrally with the reel; and a magnetic sensor attached to the housing.

Abstract: A rebar tying tool may include a controller configured to selectively execute one of a plurality of control modes including a single-action control mode and a repetitive-action control mode. While the controller executes the single-action control mode, a tying mechanism may perform a tying operation in response to an activation of a manipulation member by a user. While the controller executes the repetitive-action control mode, the tying mechanism may perform the tying operation in response to a detection of the at least one of rebars by a detection mechanism.

Abstract: A driving tool includes a first piston slidably disposed within a cylinder chamber and having an elongated driving part configured to drive a struck material. A second piston is configured to generate compressed air within the combustion chamber. A compressed air supply passage enables communication between the compression chamber and the cylinder chamber. A valve member opens and closes the compressed air supply passage. A relay member mechanically connects an electric motor with the valve member. The valve member opens and closes the compressed air supply passage via the relay member.
