Abstract: A cutter machine may include a first blade, a second blade configured to rotate relative to the first blade, a base member supporting the first blade and the second blade, a screw member including a head portion and a shaft portion extending from the head portion which is a proximal end of the shaft portion, wherein the screw member fastens the first blade and the base member to each other, a looseness restraint member attached to the shaft portion and configured to be pressed by the head portion to restrain loosening of the screw member, and a fall-off restraint member attached to the shaft portion on a distal side of the shaft portion relative to the looseness restraint member and configured to restrain the looseness restraint member from moving relative to the shaft portion in a direction from a proximal side to the distal side of the shaft portion.

Abstract: A working machine system may include a working machine, a working machine holder, and a detection mechanism configured to detect whether the working machine is held by the working machine holder. The working machine may be configured to be switched between a first state and a second state in which a predetermined switching manipulation is required to switch to the first state. When the detection mechanism detects that the working machine is not held, the working machine may switch from the first state to the second state in response to the working machine being unattended for a first predetermined time period. When the detection mechanism detects that the working machine is held, the working machine may switch from the first state to the second state in response to the working machine being unattended for a second predetermined time period which is longer than the first predetermined time period.

Abstract: An electrically powered gardening tool of the type which includes a speed-reduction gear mounted in place to be driven by operation of an electric motor, a crank-cam in the form of overlapped eccentric disk plates fixed to a bottom surface of the speed-reduction gear by means of connecting pins for rotation therewith, and a pair of relatively reciprocating shear blades assembled with the eccentric disk plates. In the gardening tool, an elastic bushing is disposed in a mounting hole formed in the speed-reduction gear or each eccentric disk plate of the crank-cam for engagement with the connecting pins fixed to the eccentric disk plate or the speed-reduction gear, and a stopper is provided to restrict deformation of the elastic bushing caused by load applied to the crank-cam.

Abstract: An electrically powered garden tool includes an electric motor mounted upright within an outer shell housing, a pair of relatively reciprocating shear blades assembled to be driven by operation of the motor through a crank mechanism provided within a lower portion of the outer shell housing, and a cooling fan assembled to be driven by operation of the motor for introducing outside air into an upper portion of the outer shell housing to exhaust the introduced air from a lower portion of the outer shell housing. In the garden tool, a downward exhaust opening is formed within a lower end peripheral wall of the outer shell housing enclosing the crank mechanism such that the air spouted by rotation of the cooling fan blows out downward from the downward exhaust opening to restrain the occurrence of blowing noise of the air.
