摘要： A transmission has a movable transmission part movably connected to a fixed transmission part via a shaft to undergo pivotal movement relative to the fixed transmission part about an axis of the shaft. Each of the transmission parts has a hollow cylindrical connecting portion through which the shaft extends. One of the connecting portion of the movable transmission part and the connecting portion of the fixed transmission part is received in the other of the connecting portions with a single seal member disposed therebetween so that an internal space of the fixed transmission part and an internal space of the movable transmission part communicate with each other to thereby form a single hermetically-sealed space for holding therein a lubricating oil.

摘要： A tiller includes an engine, a transmission mechanism, and a rotor shaft having tillage tines mounted thereon. The transmission mechanism transmits a motive power of the engine to the rotor shaft to thereby cause the tillage tines to perform a tilling operation. The tiller also includes a tranmission case having the transmission mechanism housed therein, and a fender disposed to cover the tillage tines. The fender is mounted to the tranmission case by bolts. Each bolt has a portion projecting downwardly from the fender. The tiller further includes a guard member extending downwardly from the transmission case to a level lower than the downwardly projecting portion of each bolt. The guard member guards the bolts against a foreign object thrown upwardly by the tillage tines during the tilling operation.

摘要： A walk-behind working machine has a drive source, wheels rotationally driven by the drive source, and a traveling clutch for transmitting driving power from the drive source to the wheels. A driving member is disposed in the case and has a first friction surface. A driven member is mounted in the case for undergoing rotation relative to the driving member and has a second friction surface positioned to be brought into surface contact with the first friction surface at a preselected surface pressure. A characteristic curve of the traveling clutch plotted in a coordinate system including a vertical axis representing a coefficient of friction between the first and second friction surfaces and a horizontal axis representing a parameter obtained by dividing by the preselected surface pressure a product of a viscosity of the lubricating oil and a number of times the driven member rotates relative to the driving member per second has a first straight line and a second straight line connected to the first straight line via a bent point. The preselected surface pressure is determined so that the bent point corresponds to a switch point when the working machine is switched from a first state in which the walk-behind working machine operates at a high load to a second state in which the walk-behind working machine operates at a low load.

摘要： In a clutch mechanism, a disc-shaped friction plate is disposed in a housing and an oil seal is interposed between an inner circumferential surface of the housing and the outer circumferential surface of the friction plate. The oil seal applies an inward radial force to the friction plate which, when the friction plate starts to rotate, gives rise to a circumferential frictional force tending to prevent the friction plate and a plurality of clutch pins fitted in pin-holding grooves formed in an inner circumferential surface of the friction plate from moving. Consequently, a stable frictional force is obtained between the housing side and the friction plate. Because the force providing the friction acts in the radial direction of the friction plate, no spring for providing an axial thrust is required and the length direction dimension of the driving member can be made small and the clutch mechanism can be made compact.

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： 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.
