To provide an elevation caster which is easily applied to a custom-made carriage and bears a heavy overload at an upper position where it is not grounded on a ground surface, and a carriage comprising the elevation casters.SOLUTION: An elevation caster 4A moves down, when an operation lever 8 is pressed down, to a lower position where a wheel 5 is grounded on a ground surface as a fork member 7 rotates through a coupling member 9, and the load placed on the wheel 5 is borne as the operation lever 8 abuts on a second rotation restriction part 63b. When the operation lever 8 is pressed up, the elevation caster moves up to an upper position where the vehicle 5 is not grounded on the ground surface as the fork member 7 reverses through the coupling member 9, and the load placed on the wheel 5 is borne as a second rotary shaft S2 abuts on a first rotation restriction p art 62b in a long-hole shape.SELECTED DRAWING: Figure 2

    【課題】特注品の台車への適用が容易で、かつ地面に接地しない上部位置での耐過重性が高い昇降キャスタと、この昇降キャスタを備えた台車とを提供する。【解決手段】昇降キャスタ4Aは、操作レバー8を押し下げると、連結部材9を介してフォーク部材7が回動して車輪5が地面に接地する下部位置へと下降し、車輪5に付与された荷重は、操作レバー8と第2の回動規制部63bとの当接によって受け止められる。操作レバー8を押し上げると、連結部材9を介してフォーク部材7が逆方向に回動して車輪5が地面に接地しない上部位置へと上昇し、車輪5に付与された荷重は、第2回動軸S2と長孔状の第1の回動規制部62bとの当接によって受け止められる。【選択図】図2
