PROBLEM TO BE SOLVED: To prevent stop of travel of a cage truck due to the fact that a rotatable wheel of a caster, which exists at each position of bottom four corners of the cage truck, contacts a cage truck side face contact drive part.SOLUTION: A drive unit, which is provided on a floor surface and transports a cage truck 1 having a substantially rectangular parallelepiped shape, has cage truck side face contact drive parts 6, 7 which are respectively provided on both sides of a transportation route of the cage truck 1, and a drive tire is rotated while a travel surface thereof being pressed onto and being brought into contact with a lower part of a side face of both cage trucks 1, whereby the cage truck 1 is transported in a direction of travel of the transportation route. The cage truck 1 has a caster 13 which has a rotatable wheel at each position at bottom four corners thereof. Portions of both cage truck side face contact drive parts 6, 7 which faces the wheel of the cage truck 1 below the drive tire are retreated in a direction of separating from the cage truck 1 so that the wheel is not brought into contact with any of both cage truck side face contact drive parts 6, 7 even if the wheel is squeezed out from a right side face and a left side face of the cage truck 1 during rotation.SELECTED DRAWING: Figure 13
【課題】カゴ台車の底部四隅の各位置に存在するキャスタの旋回自在な車輪がカゴ台車側面接触駆動部と接触してカゴ台車の搬送が停止するのを防止する。【解決手段】略直方体形状のカゴ台車1を搬送する床面上に設けらた駆動ユニットは、カゴ台車1の搬送経路の両側にそれぞれ設けられたカゴ台車側面接触駆動部6、7を有し、駆動タイヤは、その走行面を両カゴ台車1の側面の下方にばね力で押し付けられて接触しながら回転し、それによりカゴ台車1を搬送経路の進行方向に搬送させる。カゴ台車1は、その底部四隅の各位置に旋回自在な車輪を持つキャスタ13を有し、車輪が旋回時にカゴ台車1の右側面及び左側面から外側にはみ出しても車輪が両カゴ台車側面接触駆動部6、7のいずれとも接触しないように両カゴ台車側面接触駆動部6、7の駆動タイヤより下方のカゴ台車1の車輪に面する部分をカゴ台車1から離れる方向に後退させている。【選択図】図13
