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: A working machine may include a working unit, a prime mover configured to drive the working unit, a housing that supports the working unit and houses the prime mover, a trigger lever extending through a through hole defined in the housing so as to be located inside and outside the housing and configured to be manipulated by a user, a sensor configured to detect a movement of the trigger lever, and a control unit configured to control the prime mover based on a detection result by the sensor. The trigger lever may be rotatably supported by the housing via a rotation shaft. The trigger lever may include a block portion that has a shape of a substantially solid of revolution about a rotation axis of the trigger lever. A peripheral edge of the through hole may include a facing edge that faces an outer circumferential surface of the block portion.

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.
