芝刈機は実用に供されている。(Prior Art) A power lawn mower is in practical use, which is equipped with a cutter blade that rotates in a horizontal plane within a cutter housing, has four wheels, and has the cutter blades and wheels driven by an engine.
以上の芝刈機においてカツタハウジングを軽量
化、成形の容易化、材料費の節減等のコストダウ
ンの要請から合成樹脂にすることが望まれる。 In the above-mentioned lawn mowers, it is desired that the cutter housing be made of synthetic resin in order to reduce costs such as weight reduction, ease of molding, and reduction in material costs.

の剛性が不足がちとなる。(Problems to be solved by the invention) By the way, when the cutter housing is molded from synthetic resin, it tends to lack rigidity compared to metal, and especially the bosses that support the front and rear wheel shafts are areas where stress is concentrated. Therefore, it is necessary to increase the rigidity.
That is, FIG. 4 schematically shows a conventional cutter housing made of cast aluminum alloy, etc. The cutter housing 100 has a boss part 101 supporting the front wheel shaft at the front and a rear wheel shaft supporting the rear wheel. A boss portion 102 is provided, and a flange portion 103 is provided on both left and right sides.
103, but if a cutter housing having the same shape as this is molded from synthetic resin, the flange portions 103, 103 and the boss portions 101, 102 will be formed.
Because there is a distance between the boss parts 101 and 102
The rigidity tends to be insufficient.

た。(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention molds the cutter housing of a power lawn mower from synthetic resin, and also provides axle supporting parts formed at the front and rear parts of the cutter housing. The boss portion and the flange portions formed on both sides of the cutter housing are integrally connected to improve the rigidity of the boss portion and the vicinity of the boss portion.
