To widen a change range of a wheel diameter of a diameter change wheel.SOLUTION: A diameter change wheel 20 comprises: a hub member 22 rotating around an axis of an axle O; a plurality of arm members 21A to 21F each having one end side connected to the hub member; a rotation member 23 rotatively driven around the same axis as the axle by a driving force of an external drive source; a diameter change mechanism 24 changing a radial position of each wheel on the other end sides of the plurality of arm members by the relative rotation of the rotation member with respect to the hub member; and a wheel outer peripheral member 26 supported by the other end sides of the plurality of arm members. The one end sides of the plurality of arm members are each connected to the hub member to be rotatable around an arm shaft 24a parallel with the axle, so that the diameter change mechanism changes the radial position of each wheel of the other end sides of the plurality of arm members by rotating the plurality of arm members around the arm shaft by the relative rotation of the rotation member with respect to the hub member.SELECTED DRAWING: Figure 1

    【課題】径可変車輪の車輪径の変更範囲を広くする。【解決手段】車軸Oの軸回りで回転するハブ部材22と、ハブ部材に一端側が接続される複数のアーム部材21A~21Fと、外部駆動源の駆動力により車軸と同軸回りに回転駆動される回転部材23と、ハブ部材に対する回転部材の相対回転により複数のアーム部材の他端側の各車輪径方向位置を変更する径変更機構24と、複数のアーム部材の他端側に支持される車輪外周部材26と、を備えた径可変車輪20であって、複数のアーム部材の一端側は、ハブ部材に対し、車軸と平行なアーム軸24a回りで回動自在にそれぞれ接続されており、径変更機構は、ハブ部材に対する回転部材の相対回転によって複数のアーム部材をアーム軸回りでそれぞれ回動させることにより、複数のアーム部材の他端側の各車輪径方向位置を変更する。【選択図】図1
