PROBLEM TO BE SOLVED: To enhance handling performance of a transport truck.SOLUTION: A transport truck has: a truck body 13; a support wheel 23 which is rotated in association with movement of the truck body 13; a support cradle 35 which is rotated upwards with respect to the truck body 13 by receiving a force for pushing a grip and is rotated downwards with respect to the truck body by releasing a hand from the grip; a spring device 31 which is supported on the support cradle 35; a charging wheel 36 which is connected to an input shaft of the spring device 31; and a drive wheel 37 which is connected to an output shaft of the spring device 31. When pushing the grip thereby moving the track body 13, the drive wheel 37 is separated from a floor surface, and an outer peripheral surface of the charging wheel 36 contacts an outer peripheral surface of the support wheel 23. When the hand is released from the grip, the charging wheel 36 is separated from the support wheel 23, and the drive wheel 37 contacts the floor surface.SELECTED DRAWING: Figure 5
【課題】本発明は、搬送台車の使い勝手を向上させることである。【解決手段】本発明に係る搬送台車は、台車本体13と、台車本体13の移動に伴って回転する支持車輪23と、取っ手を押す力を受けて台車本体13に対して上回動し、取っ手から手を離すことで台車本体に対して下回動する支持架台35と、支持架台35に支持されているバネ装置31と、バネ装置31の入力軸に連結されたチャージ用車輪36と、バネ装置31の出力軸に連結された駆動車輪37とを有しており、取っ手を押して台車本体13を移動させる際、駆動車輪37が床面から離れ、チャージ用車輪36の外周面が支持車輪23の外周面に当接し、取っ手から手が離されると、チャージ用車輪36が支持車輪23から離れ、駆動車輪37が床面に当接する。【選択図】図5
