摘要： A walk-behind work machine in which vibration produced by the driving of an engine is not readily transmitted to an operating handle. The work machine includes a work-machine body having a plurality of mounting parts to which an engine is joined. The mounting parts include a high-rigidity mounting part positioned at a maximally rigid part on the work-machine body, and other mounting parts exclusive of the high-rigidity mounting part. The engine is joined securely to the other mounting parts and is joined more loosely to the high-rigidity mounting part than to the other mounting parts.

摘要： A rotation direction switching device for switching the rotation direction of a drive shaft includes a pulley unit for switching the rotation direction of the drive shaft. The pulley unit has a forward rotation drive belt and a reverse rotation drive belt. The forward rotation drive belt extends between the forward rotation drive pulley and a forward rotation driven pulley. The reverse rotation drive belt extends between a reverse rotation drive pulley and a reverse rotation driven pulley. When the drive shaft is forwardly rotated, the forward rotation belt is placed in a tensioned state, and the reverse rotation belt is switched to a relaxed state. When the drive shaft is reversely rotated, the reverse rotation belt is placed in a tensioned state, and the forward rotation belt is switched to a relaxed state.

摘要： A continuously shifting-type steering system includes a pair of left and right hydrostatic continuously variable transmissions each of which is comprised of a hydraulic pump and a hydraulic motor, and a pair of left and right planetary gear mechanisms each having a first sun gear, a second sun gear, a two-step planetary gear and a carrier. A first driving gear connected to an engine, is operably connected commonly to the left and right first sun gears. Left and right second driving gears secured to motor shafts of the left and right hydraulic motors, are operably connected to the left and right carriers, respectively. Left and right output shafts are operably connected to the left and right second sun gears, respectively. Thus, it is possible to provide an increase in the shifting range of the continuously shifting-type steering system, and an enhancement in low-output performance.

摘要： A motorized vehicle has a vehicle body, at least a pair of wheels mounted on the vehicle body for undergoing rotation to cause the motorized vehicle to undergo travelling, and a pair of electric motors each mounted on the vehicle body to selectively undergo forward and reverse rotation to rotationally drive a respective one of the wheels. A first switch is connected to the electric motors so that operation of the first switch causes the electric motors to undergo rotation simultaneously in opposite directions to turn the motorized vehicle in a first direction while the motorized vehicle does not undergo travelling. A second switch is connected to the electric motors so that operation of the second switch causes the electric motors to undergo rotation simultaneously in opposite directions to turn the motorized vehicle in a second direction opposite to the first direction while the motorized vehicle does not undergo travelling.

摘要： A snow removing machine which throws up snow collected by an auger with a blower and throws out the snow via a chute is provided. The chute is provided on a blower housing enclosing the blower. The chute is placed on the right or left of the blower housing in a body width direction, so as to receive snow thrown up by centrifugal force of the blower. In a dead space on the opposite side to the chute, a control unit for controlling rotations of electric motors and so on and a battery for supplying power to the electric motors are disposed.
