The brush cutter is provided with a vibration absorbing member which fits in a tubular portion side fitting portion provided in the tubular portion and fits in a box side fitting portion provided in the floating box.

Brush cutter

A lawn mower includes a cutter blade that is an elongated member extending in opposite horizontal directions with respect to a vertical rotation shaft. The cutter blade includes, on each of its longitudinally opposite end portions, a blade section formed along the front edge, in a rotating direction of the cutter blade, of the end portion, and an air lift section extending from the front edge while curving rearward and upward. The air lift section has a vertical downward wing formed integrally thereon and extending downward via a bent section that is bent downward from at least a rear half portion, in the rotating direction, of an outer peripheral edge of the air lift section. The bent section has a radius set to gradually increase as the air lift section curves rearward and upward in the rotating direction.

An outer rotor motor includes a mounting seat portion provided inside a motor case, and a protruding portion protruding from the mounting seat portion. An inner stator has a stator opening portion formed centrally thereof, and a mounting portion is formed adjacent the stator opening portion. A vibration isolating member is interposed between the mounting seat portion and the mounting portion with the stator opening portion telescopically fitting over the protruding portion. The vibration isolating member includes a pair of foam rubber layers and a metal base material sandwiched between the pair of foam rubber layers. A bolt fastens the mounting seat portion and the mounting portion together while compressing the vibration isolating member.

Outer rotor motor

A lawn mower includes: a rotation shaft extending vertically in a downwardly-opening housing; and a cutter blade rotatably mounted on the rotation shaft. The cutter blade is an elongated member extending in opposite horizontal directions and having two bent sections formed on respective ones of its longitudinally opposite end portions. The two bent sections are bent in opposite directions as viewed in the axial direction of the rotation shaft. The cutter blade has, on each of the bent sections, a convex cutter blade section formed along a convex edge of the bent section and a concave cutter blade section formed along a concave edge of the bent section. The convex cutter blade section on each of the bent sections has a smaller cutting edge angle than the concave cutter blade section.
