PROBLEM TO BE SOLVED: To provide a carriage and the like capable of fitting and fixing a seat plate of a caster easily and reliably to a synthetic resin base board and coping with down-sizing and weight-saving of the base board.SOLUTION: A carriage 1 comprises a synthetic resin base board 10 and a plurality of casters 50 and can be used for transporting an article while loading the article on the base board 10. Seat plate reception parts 20 and retainer reception parts 30 are formed in four corners of an undersurface of the base board 10. The retainer reception parts 30 are adjacent in a horizontal direction on the side of seat plate insertion ports 21 of the seat plate reception parts 20. When a retainer member 40 is displaced in a vertical direction and slid in a prescribed direction in the retainer reception part 30 against a bias force of a leaf spring 44, a retainer lock part 35 and a lock projection part 49 engage with each other by the bias force of the leaf spring 44, and the retainer member 40 can be fixed to a prescribed position in the retainer reception part 30. Thus, with a simple operation, a seat plate 51 of the caster 50 can be easily and reliably fitted and fixed in the seat plate reception part 20.SELECTED DRAWING: Figure 12
【課題】合成樹脂製の台盤に対して、キャスターの座板を容易かつ確実に取付固定することができ、更に、台盤の小型化及び軽量化に対応可能な台車等を提供する。【解決手段】台車1は、合成樹脂製の台盤10と、複数のキャスター50を有しており、台盤10上に物品を積載して運搬作業に利用し得る。台盤10下面における四隅には、座板受容部20とリテーナ受容部30が形成されており、リテーナ受容部30は、座板受容部20の座板挿入口21側において水平方向に隣接している。リテーナ受容部30内を板バネ44の付勢力に抗して、リテーナ部材40を垂直方向に変位させつつ、前記所定方向へスライド移動させると、板バネ44の付勢力によってリテーナ係止部35と係止凸部49が係合して、リテーナ部材40をリテーナ受容部30内の所定位置に固定でき、簡単な操作で、キャスター50の座板51を前記座板受容部20内に、容易かつ確実に取り付け固定する。【選択図】図12
