摘要： A working machine includes: an output shaft to which a tip tool is attachable; a housing rotatably supporting the output shaft; and a protection cover attached to the housing so as to cover an outer periphery of the tip tool which is attached to the output shaft. The protection cover is configured to be displaceable between a processing position to expose a part of the outer periphery of the tip tool to thereby allow cutting of a workpiece, and a protecting position to cover the outer periphery of the tip tool more than in the processing position, and is biased by a biasing member to be displaced from the processing position to the protecting position.

摘要： A work apparatus is comprised of a blower unit including a drive motor; a volute casing, a fan rotatably supported within the volute casing and driven by the drive motor, and an airflow duct connected to the volute casing, thereby blowing out or sucking in air through the airflow duct; and of an airflow tube coupled to the airflow duct of the blower unit and having an open distal end for blowing out or sucking in air through the airflow tube. The airflow tube is provided with a grip handle adapted for being held and operated by the operator. Within the airflow tube is arranged an electrically conductive wire at least between the grip handle and the open distal end, beyond which is provided an electrically grounding wire connected to the electrically conductive wire and drooping therefrom to be touchable to earth.

摘要： A nozzle pipe is to be coupled to a distal open end of an air blow-off tube of a blower apparatus for regulating the profile of an airflow blown out from the blow-off tube. The nozzle pipe comprises an outer tubular member and an inner tubular member coaxially disposed within the outer tubular member. The inner tubular member has a circumferential wall formed with apertures allowing air passage therethrough. The outer tubular member and the inner tubular member provides a first space therebetween to form a first air passage, while the inner tubular member provides a second space therein to form a second air passage. A plurality of rectifier fins are disposed inward from the outer tubular member, standing radially and extending longitudinally, and spaced apart circumferentially from each other. The fins extend inclined at an angle with reference to the longitudinal central axis of the tubular members.

摘要： A handcart may include a prime mover, a first ground-contact part, a second ground-contact part, a clutch mechanism configured to switch between a transmission state and a non-transmission state, a differential mechanism configured to switch between a non-locking state and a locking state, a switching unit configured to switch a state of the clutch mechanism and a state of the differential mechanism; and an operation unit. The switching unit may be configured to: in response to a user’s first operation, switch the state of the clutch mechanism between the transmission state and the non-transmission state without switching the state of the differential mechanism, and in response to a user’s second operation, switch the state of the differential mechanism between the non-locking state and the locking state without switching the state of the clutch mechanism.
