、騒音が大きく、商品価値の低いものであった。In the conventional grass mower as described above, the overall length of the machine body is long because the drive device such as the engine that drives the cutting blade device etc. is located behind the wheels. As a result, the aircraft was unable to make sharp turns, resulting in poor work efficiency. Furthermore, a large vehicle is required to transport the mower by placing it on the platform of a vehicle. Furthermore, since the drive device such as the engine was not completely covered, the noise was loud and the product value was low.

に構成してもよい。Effects of the Invention The lawn mower according to the present invention has a driving device 3 such as an engine provided inside the wheels 1 supporting the machine body.
is activated to drive the cutting blade device 2 and perform grass cutting work. It should be noted that the drive device 3 may be configured to drive and rotate not only the cutting blade device 2 but also the wheels 1 to cause the machine body to travel on its own.

覆されるため、騒音が小さく、商品価値が高まる。[0006] With this configuration, the drive device 3, which was conventionally located behind the wheels 1, is housed inside the wheels 1, so the overall length of the machine is shortened, turning is effective, and work efficiency is improved. Moreover, the vehicle for transporting the mower can also be small. Furthermore, since the driving device 3 such as the engine is covered by the wheels 1, noise is reduced and the product value is increased.

The wheels 1 of the lawn mower are made of an elastic material such as rubber or resin and have a cylindrical shape. The engine 4 (drive device 3) is disposed in the hollow portion of the wheel 1 with its output shaft oriented in a direction that coincides with the rotational axis of the wheel 1. A support plate 5 is attached to the output shaft side of the engine 4. After passing through the support plate 5, the output shaft drives a drive shaft 7 via a centrifugal clutch 6. A central gear 8 is attached to the drive shaft 7, and a boss 9 is loosely fitted near the tip of the drive shaft 7. Three arms 10, 10, 10 are attached to the boss 9 in the radial direction,
The tips of support shafts 11, 11, 11 provided from the support plate 5 are fitted into the tips of the arms 10, 10, 10. Intermediate gears 12, 12, 12, which mesh with the center gear 8, are rotatably attached near the tips of the support shafts 11, 11, 11. The intermediate gears 12, 12, 12 mesh with an inner peripheral gear 13 provided on the inner peripheral surface of the side portion of the wheel 1. One end of a handle 14 is fixed to the boss 9. Further, one end of a hollow shaft 15 is attached to a portion of the engine 4 on the opposite side to the output shaft, aligned with the direction of the rotation axis of the wheel 1. The other end of the hollow shaft 15 is loosely fitted into and penetrates a boss 17 provided at the center of a side plate 16 that closes the other side of the wheel 1. The other end of the handle 14 is fixed to the boss 17. The handle 14 is formed in a U-shape. A throttle wire 19 interlocked with a throttle lever 18 provided on the handle 14 is passed through the hollow shaft 15, so that the rotational state of the engine 4 can be freely adjusted. Further, a refueling pipe 20 is also passed through the hollow shaft 15 to enable refueling to the fuel tank 21 of the engine 4.

ある。From the tip of the drive shaft 7 to the drive case 22
The cutting blade device 2 is driven through the. The cutting blade device 2 may be of a clipper type, a spiral blade type, an endless band type cutting blade, or the like. The transmission shaft 23 within the drive case 22 is provided with an emergency stop device 24 for fixing the transmission shaft 23 non-rotatably. The emergency stop device 24 includes a stop cam 25 slidably provided on the transmission shaft 23, which is attached to the drive case 22.
It is to be engaged with a stop plate 26 fixed to
With the stop lever 27 provided on the handle 14,
It is configured to be operated via an operating wire 28. When a dangerous situation occurs during work, the emergency stop device 24 is activated by the operator operating the stop lever 27 to stop the rotation of the transmission shaft 23. As a result, the cutting blade device 2 stops instantaneously, and the engine 4 is also overloaded, causing the engine to stop.
