To solve a problem in that, in a wooden wheel having a rectangular parallelepiped central member, a grounding portion which is a corner portion of the central member is likely to be unevenly worn.SOLUTION: Provided is a wooden wheel having an intermediate member with parallel opposed surfaces, and a first end layer member and a second end layer member laminated in parallel to the opposed surfaces, the wooden wheel being formed as a wheel as a whole. The intermediate member has a central member having an axis hole and formed as a rectangular parallelepiped having parallel surfaces constituting the opposed surfaces, and a side member including a plurality of plates laminated along a side face opposed at the right angle to the parallel surfaces of the central member. A reinforcement member is arranged between the opposed surfaces and the first end layer member and the second end layer member. Even through the wooden wheel has the rectangular parallelepiped central member, uneven wear is restrained.SELECTED DRAWING: Figure 1
【課題】直方体の中心部材を有する木製車輪では、中心部材の角の部分にあたる接地部分が偏摩耗しやすいという課題があった。【解決手段】平行な対向面を有する中間部材と、前記対向面に平行に積層された第1端層部材および第2端層部材を有し、全体が車輪状に形成された木製車輪であって、前記中間部材は、軸心孔を有し、前記対向面を構成する平行面を有する直方体状に形成された中心部材と、前記中心部材の前記平行面に直角に対向する側面に沿って積層された複数の板材で構成された側部材を有し、前記対向面と前記第1端層部材および前記第2端層部材の間に補強部材が配置されていることを特徴とする木製車輪は、直方体の中心部材を有していても、偏摩耗が抑制される。【選択図】図1
