PROBLEM TO BE SOLVED: To provide a carriage which can stabilize a caster mounting state while being configured to enable relatively easy attaching/detaching of a caster.SOLUTION: A carriage 1 includes a base board 2 having an approximately rectangular shape in plan view, casters 3 each equipped with an approximately tabular seat plate 23 mounted to an undersurface side of the base board 2, and retainers 4 each of which mounts the caster 3 to the base board 2. The base board 2 has a seat plate installation part 10 and a retainer installation part 11 adjacent to the seat plate installation part 10. The seat plate 23 is made to enter into the retainer installation part 11 and then slid to a seat plate installation part 10 side, whereby both side edge parts of the seat plate 23 are inserted into a clearance 14 formed in the seat plate installation part 10 to support an undersurface side. The retainer 4 includes a main body part 31 which is engaged with the retainer installation part 11, and an insertion part 32 which projects from one side part of the main body part 31. The insertion part 32 is brought into a state being inserted into the clearance 14, and then the main body part 31 is rotated about the insertion part 32 until engaged with the retainer installation part 11, whereby the retainer 4 is mounted. |
