Description of the Related Art A conventional hand-operated brush cutter has a frame for holding an engine, a pair of left and right wheels provided at a lower end of the frame, a handle provided at an upper end of the frame, and a pair of left and right wheels. A blade provided with a cutting blade which is provided in front and which is rotated by an engine is known. When cutting grass with this hand-operated brush cutter, the operator holds the handle while moving it forward while pushing the mowing blade to a certain height, and swinging the handle to the left or right to rotate the mowing blade. I used to shake it to the left and right to cut wide.

It is shaped like a barrel with a diameter of 50 mm to 250 mm. More specifically, the wheel 3 is formed in a hollow barrel shape by omitting the conventional wheel and tire and by blow molding a synthetic resin such as polypropylene (PP). Further, the left and right side plate parts 17, 17 corresponding to the barrel-shaped bottom wall are formed in an inward concave shape (conical concave shape), and a bearing 18 such as a sliding bearing (bush) is fitted to the axial center portion of the side plate part 17. I'm wearing it. Axle 10
It is inserted into the two bearings 18, 18 of the wheel 3 and held in the form of a doubly supported beam.

The left and right wheels 3, 3 are mounted on the axle 10 so that the vehicle width W can be adjusted. Specifically, the mounting structure of the wheel 3 on the axle 10 will be described. As shown in FIG. 3A, the pipe body 19 (shorter than the axle 10) is provided at the lower end 23b of the center frame 6.
Are provided in the left and right horizontal direction, and the axle 10 is inserted into the pipe body 19 with the left and right end sides protruding. Then, the bearings 18, 18 of the wheel 3 are externally fitted to the end side of the axle 10, and the wheel 3 is attached.
By externally fitting a cylindrical spacer 24 between 19 and 19 and attaching a retaining member 25 (for example, a split pin) to the end of the axle 10,
As shown in FIG. 4 (a), the vehicle width W of the left and right wheels 3, 3 can be set to a large value, so that the brush cutter can be stably run even on the ground G having a lot of unevenness (described above). You can At this time, since the wheels 3 and 3 are barrel-shaped, the stability becomes synergistically excellent.

As shown in Fig. 4 (b), the vehicle width W is reduced by using the lock to prevent the ground (road surface) with a narrow width such as a ridge.
Even G can run. It should be noted that the axle 10 is held in a doubly supported beam shape by the two left and right bearings 18, 18 with respect to the wheel 3, which is preferable in terms of strength of the axle 10, and conversely, the wheel 3 is also kept in a stable posture. Rotate while leaning.
