摘要： A handle structure of a walk-behind working machine includes: a handle having left and right raised portions extending upward from a handle frame and a cross portion interconnecting the left and right raised portions; and a main clutch lever shiftable from a clutch-OFF position to a clutch-ON position by being pivoted into pressed abutment against the cross portion. The main clutch lever is constructed in such a manner that, when the main clutch lever is in abutment against the cross portion, a space for allowing a human operator to grip the left and right raised portions is secured between the left and right raised portions and the main clutch lever.

摘要： Operation mechanism of a working machine includes a main clutch lever pivotably provided on an operating handle, and a pivot member operable in interlocked relation to pivoting operation of the main clutch lever. The pivot member pivots about a pivot point differing in position from a pivot point of the main clutch lever. When fully pulled by pivoting operation of the main clutch lever, the cable member is located nearest to the pivot point of the pivot member, so that force reverse-pivoting the pivot member is reduced.

摘要： A power transmission mechanism for transmitting a driving force from a drive shaft to a driven member of a gear via a one-way clutch is provided. The one-way clutch includes a swinging clutch portion swingably fitted in a clutch portion housing groove formed in a first end portion of the drive shaft. The swinging clutch portion has a cylindrical portion as the axis of rotation and a projecting portion. When the drive shaft rotates, the projecting portion of the swinging clutch portion is raised by a slit of a collar fitted onto the drive shaft, engaging one of a plurality of engaging grooves formed in the inner peripheral surface of the driven member. When the drive shaft does not rotate, the swinging clutch portion lies down, and the projecting portion does not engage any engaging groove, allowing the driven member to rotate bidirectionally relative to the drive shaft.

摘要： A motor-assisted single-wheel cart is provided with a motor for generating an assisting power in response to an operation force when operating an operation handle by a human hand, and a power transmission mechanism for transmitting an output of the motor to an axle. The motor is arranged rearwardly upwardly of the axle so as to be positioned within a space surrounded by an upper horizontal member and a lower member positioned below the upper horizontal member constituting a vehicle body frame constituting the cart as viewing the vehicle body frame from a side surface thereof. The power transmission mechanism has a first speed reduction mechanism arranged near the motor, a second speed reduction mechanism arranged near the wheel and a transmission shaft for connecting them. The transmission shaft is inserted to the first and second speed reduction mechanisms so as to be capable of being drawn out.

摘要： Driving power is transmitted to an output shaft, via driving and driven bevel gears, to a cutter blade. A gearbox supports the output shaft via first and second bearings. The second bearing is engaged by an engaging member to be prevented from axial movement, toward the blade, relative to the gearbox and supports the output shaft near the cutter blade. The output shaft is connected to the driven bevel gear such that it is prevented from rotation relative to the driven bevel gear but allowed to move axially. When the engaged state, by the engaging member, of the second bearing is canceled, the shaft is allowed to axially move toward the cutter blade until the shaft becomes rotatable relative to the driven bevel gear, at the same time of which a retaining stopper prevents the shaft from further axial movement.

摘要： A tiller for cultivating soil has a power source and a tilling shaft mounted for undergoing rotation by a driving force supplied from the power source. The tilling shaft has a hollow outer shaft and an inner shaft extending through the outer shaft. The inner shaft has a variable rotating speed and/or direction of rotation relative to the outer shaft. A power transmission mechanism transmits a driving force from the power source to the tilling shaft. The power transmission mechanism has a first power transmission system for transmitting the driving force from the power source to the outer shaft and a second power transmission system transmitting the driving force from the power source to the inner shaft. The second power transmission system has a hydrostatic transmission comprised of a hydraulic pump and a hydraulic motor for effecting a stepless change of the rotating speed of the inner shaft as well as a selective change of its direction of rotation. Tilling claws are disposed on the tilling shaft for tilling soil.
