To provide a caster device which can easily switch an extending state and a storage state of a wheel.SOLUTION: A caster device includes: a wheel 130; an axle 120 rotatably supporting the wheel 130; and an axle support 110 having an axle movable path which movably supports the axle 130. The axle movable path has: an axle 120 storage positioning part at which the wheel 130 is stored in the axle support 110; and an axle 120 extension positioning part at which the wheel 130 extends from the axle support 110. The axle 120 is alternately moved between the storage positioning part and the extension positioning part according to vertical movement of the axle support 110.SELECTED DRAWING: Figure 2
【課題】車輪の張出状態と格納状態とを容易に切り替えることができるキャスター装置を提供する。【解決手段】車輪130と、車輪130を回転自在に支える車軸120と、車軸130を移動可能に支持する車軸可動経路を有する車軸支持体110と、を備え、車軸可動経路は、車輪130が車軸支持体110に格納される状態となる車軸120の格納位置決め部と、車輪130が車軸支持体110から張り出した状態となる車軸120の張出位置決め部と、を有し、車軸支持体110の上下動に応じて、車軸130を、格納位置決め部と張出位置決め部との間で交互に移動させる。【選択図】図2
