Abstract: A driving tool includes a piston configured to move in a driving direction due to gas pressure, and a driver configured to move integrally with the piston to strike a fastener. The driver includes a plurality of rack teeth formed along a driving direction. The driving tool includes a wheel having a plurality of engaging portions to engage the plurality of rack teeth at its outer circumference. The driver is moved in a counter-driving direction as the wheel rotates. The plurality of engaging portions of the wheel includes at least one advancing/retracting engaging portion configured to move with respect to a shaft member of the wheel. The driver has a tooth groove between adjacent rack teeth of the plurality of rack teeth. One tooth groove is configured to receive the advancing/retracting engaging portion and has a depth deeper than at least one other tooth groove.

Abstract: An impact tool has less size increase and improved striking efficiency. An impact tool includes a motor, a spindle rotatable with a rotational force from the motor and including a spindle shaft and a flange, an anvil, a hammer, first and second coil springs surrounding the spindle shaft, a cup washer, and a support ball. The anvil includes an anvil shaft to receive a tip tool and an anvil projection protruding radially outward from the anvil shaft. The hammer includes a hammer projection to strike the anvil projection in a rotation direction, a recess at a rear of the hammer, and a support groove inside the recess. The cup washer is located in the recess and supports front ends of the first and second coil springs. The support ball is located in the support groove and supports the cup washer.

Abstract: A rebar tying tool ties together two or more rebars using a wire. The rebar tying tool may include: a reel comprising the wire wound on a bobbin; a reel-holding part configured to hold the reel in a rotatable manner; a feed part configured to advance the wire from the reel by a number of turns of the wire around the rebars; and a twisting part configured to twist the wire after the number of turns of the wire has been wound around the rebars. The wire preferably has a maximum tensile load of at least 700 N. Preferably, the wire after the number of turns of the wire has been wound around the rebars has an overall maximum tensile load of at least 1,050 N, which is calculated by multiplying the maximum tensile load of the wire by the number of turns of the wire around the rebars.

Abstract: A blower includes a body having a main inlet opening and a discharge opening, a motor assembly housed in the body, and an auxiliary inlet opening. The motor assembly includes a case, a motor and a fan. The case has a first opening and a second opening. The motor is housed within the case. The fan is configured to rotate in response to driving of the motor to generate a flow of air passing the main inlet opening, the first opening, the motor, the second opening and the discharge opening in this order. A first space that communicates with the main inlet opening and the first opening of the case is formed within the body. The auxiliary inlet opening is configured to introduce the air from an outside of the body into the first space.
