- There are some as shown in Figure 8. It consists of a boss part a made of hard plastic, a disk-like spoke part b, and a rim part c, and a tire d made of rubber or vinyl chloride is fitted onto the rim part c.

あつた。(Problems to be solved by the invention) However, when mowing the lawn with the wheels of such a conventional small lawn mower, if there is a side wall e made of concrete or the like as shown in Fig. 9, the problem shown in Fig. 7 cannot be avoided. An uncut portion n appears on the edge of the side wall. In order to reduce the width of the grass, the grass was mowed by pushing it in the direction of the tire F as shown in Figure 9. With conventional tires, the sides of the tire rubbed and wore out, causing the tire to come off and making it impossible to mow the lawn. There was a problem.

A wheel for a small lawn mower fitted with a wheel, characterized in that an annular protrusion is provided on the outside of the disc-shaped spoke part, and the annular protrusion protrudes more outward than any other part of the wheel. It is.

タイヤである。(Example) Hereinafter, a detailed explanation will be given based on the illustrated example. 1 is a boss portion, 2 is a rim portion, and 3 is a disc-shaped spoke portion that connects the boss portion and the rim portion, and is reinforced by radial ribs 4. All of these are integrally formed by injection molding hard plastic. 5 is a disc-shaped spoke portion 3
It is a thick annular protrusion that protrudes outward more than any other part of the wheel, and when mowing the lawn along a side wall such as concrete, only this annular protrusion protrudes along the side wall e. It is designed to come into sliding contact with the 6 is a rubber tire fitted onto the rim portion.

イヤ６の側面が摺接することがない。 Next, the effect will be explained. When mowing the lawn along a concrete side wall, only the annular protrusion 5 comes into sliding contact with the side wall even if the front wheel is moved while pressing against the side wall, in order to reduce the amount of uncut grass as close to the concrete side wall as possible. Therefore, the side surfaces of the tires 6 do not come into sliding contact.

An annular protrusion is provided, and the annular protrusion protrudes outward more than any other part of the wheel, so that when mowing the lawn along a concrete side wall, there is as little uncut grass as possible. Even if the front wheel or the front wheel and the rear wheel are moved while being pressed against the side wall, only the annular protrusion comes into sliding contact with the side wall, so that the side surface of the tire can be protected.
