To provide a new wheel device which is used for front and rear wheels of a carriage, front wheels of a wheelchair and the like and enables getting-over of an obstacle such as a step, and the carriage having the wheel device.SOLUTION: A wheel device 10 comprises: an attachment member 16; a mortar-shaped plate body 18 which is supported by the attachment member and has an oblong-shaped cross-sectional shape; a plurality of runners 20 and a plurality of auxiliary runners 22 which are supported in a movable manner in a peripheral direction by the plate body; and wheels 24 which are supported by the runners. The plate body includes two flat plate parts which extend in the peripheral direction along the peripheral surface of the mortar shape and two curved plate parts which are continuous to both flat plate parts. Both flat plate parts are at upper and lower height positions with respect to a travel path surface of the wheel device and are vertical and parallel to the travel path surface. The wheels 24 are placed in a parallel state with respect to the travel path surface when the runners supporting the wheels are located on the flat plate part 18a at the upper position, and are placed in a standing state with respect to the travel path surface when the runners are located on the flat plate part 18b at the lower position.SELECTED DRAWING: Figure 1
【課題】台車の前後輪、車いすの前輪等としての用に供される、段差のような障害の乗り越えを可能とする新たな車輪装置及び該車輪装置を備える台車を提供すること。【解決手段】車輪装置10は、取付部材16と、取付部材に支持された長円形の断面形状を有するすり鉢形の板体18と、板体にその周方向へ移動可能に支持された複数のランナー20及び複数の補助ランナー22と、ランナーに支持された車輪24とを備える。板体は、すり鉢形の周面に沿ってその周方向へ伸びる2つの平板部及び両平板部にそれぞれ連なる2つの湾曲板部からなる。両平板部はそれぞれ車輪装置の走行路面に対して上位及び下位の高さ位置にありかつ走行路面に対して垂直及び平行をなす。車輪24は、これを支持するランナーが上位の平板部18aに位置するとき走行路面に対して平行な状態におかれまた下位の平板部18bに位置するとき走行路面に対して直立する状態におかれる。【選択図】 図1
