To provide a traction cart that is economical, rational, user-friendly, and excellent in handling owing to embodiment of a simple structure.SOLUTION: A traction cart includes: a traction bar 1 which juts out ahead of a cart base 10 and whose proximal end 1a can pivot on a shaft 11; a guide stationary caster 2 concentric with the shaft 11; a pair of left and right stationary casters 3L and 3R characterized in that a line F linking the centers of the pair of left and right stationary casters 3L and 3R overlaps a line leading to a pivot center point O for traction and wheels 32 are oriented in directions orthogonal to the line leading to the pivot center point O; and a coupling part 4 and universal casters 5 located on a rear side of the cart base 10. A distance S between the shaft 11 and an intersection point G at which a line L in a fore-and-aft direction linking the center of the shaft 11, which is located between the pair of stationary casters 3L and 3R when seen in plan, and the center of the coupling part 4 is orthogonal to the line F linking the pair of stationary casters 3L and 3R is equal to or smaller than a distance T between the coupling part 4 and the intersection point G.SELECTED DRAWING: Figure 1
【課題】シンプルな構造を実現することにより、経済的かつ合理的で使い勝手がよく取り扱い性に優れた牽引台車を提供する。【解決手段】台車ベース10の前方向へ突き出し、その基端部1aが軸11に回動可能に設けられる牽引バー1と、前記軸11と同芯の誘導固定キャスター2と、左右一対の固定キャスター3L、3Rの中心を結んだ線Fが、牽引時の旋回中心点Oからの線と重なり、旋回中心点Oからの線と直交する方向に車輪32が向く前記左右一対の固定キャスター3L、3Rと、前記台車ベース10の後側に設けられる連結部4と自在キャスター5とを備え、平面的に見て前記一対の固定キャスター3L、3R間に位置する軸11の中心と連結部4の中心とを結んだ前後方向の線Lが、前記一対の固定キャスター3L、3Rを結んだ線Fと直交して生じる交点Gと前記軸11との距離Sが、前記交点Gと前記連結部4との距離Tより同等以下の関係になる配置となる。【選択図】図1
