摘要： A brushcutter includes: a centrifugal clutch (20) that transmits a drive force of an engine from a crankshaft to a drive shaft; a clutch housing (23) covering the cooling fan and the centrifugal clutch, the clutch housing being made of a synthetic resin; and a bearing that is held inside the clutch housing (23) and supports a coupling shaft that couples the drive shaft and the centrifugal clutch (20). A volute-shaped air-flow space (27) defined including a rise wall (26) surrounding the centrifugal clutch (20) is provided inside the clutch housing (23) near an outer circumference of the centrifugal clutch (20). An inflow opening (28, 29) that lets a cooling air flowing in the air-flow space (27) flow into an inner air-flow space (53) and an outflow opening (52) that lets the cooling air flowing in the air-flow space (53) flow out to the air-flow space (27) are provided on the rise wall (26).

摘要： An RFID tag includes an inlet, an inlet attachment portion, and a ring-shaped mount portion. The inlet includes a substrate, an antenna formed on the substrate, and a circuit chip connected to the antenna. The inlet is attached to the inlet attachment portion. The ring-shaped mount portion is connected to the inlet attachment portion and is mounted on an object. The inlet is off-centered with respect to the inlet attachment portion so as to locate an upper edge of the inlet above an upper end of the ring-shaped mount portion.
