Abstract: A fastening tool includes a housing, a fastener-abutment part, a pin-gripping part held within the fastener-abutment part to be movable in a front-rear direction relative to the fastener-abutment part, a detection-target part provided to move together with the pin-gripping part, a detection device configured to detect the detection-target part, a motor, and a driving mechanism configured to move the pin-gripping part rearward from an initial position relative to the fastener-abutment part. The driving mechanism is further configured to move the pin-gripping part forward relative to the fastener-abutment part so as to return the pin-gripping part to the initial position based on a detection result of the detection device. The fastening tool is configured such that a first moving distance is adjustable, the first moving distance being a distance by which the pin-gripping part is moved from a detection position to the initial position.

Abstract: A rebar tying tool configured to tie plural rebars using a wire is disclosed herein. The rebar tying tool may include a reel supporting mechanism configured to switch between a first state of detachably supporting a reel on which the wire is wound and a second state of undetachably supporting the reel; a wire feeding mechanism configured to feed the wire from the reel; and an openable cover that at least partially covers at least one of the reel supporting mechanism and the wire feeding mechanism. The reel supporting mechanism may switch from the first state to the second state by a user operation of closing the cover, and/or may switch from the second state to the first state by a user operation of opening the cover.

Abstract: A robotic dust collector includes a body, a wheel, a wheel motor, and a suspension device. The body accommodates a storage unit to store therein dust and dirt sucked in from a suction inlet. The wheel supports the body. The wheel motor generates motive power to rotate the wheel. The suspension device includes a support member, a motive-force generating mechanism, and an adjustment mechanism. The wheel is supported rotatably about a center axis by the support member. The motive-force generating mechanism gives a motive force to the support member to generate a biasing force to cause the wheel to protrude from a bottom face of the body. The adjustment mechanism adjusts the biasing force based on a protrusion amount of the wheel from the bottom face. The suspension device gives the biasing force adjusted by the adjustment mechanism to the wheel.
