PROBLEM TO BE SOLVED: To provide a spring type assisted transportation carriage that can alleviate burden on a worker upon running start by simply assisting without mounting a motor or a battery.SOLUTION: The carriage comprises a load-carrying platform 2, a handlebar 3 provided rearward of the load-carrying platform 2, a pair of rear wheels 5 provided via a pair of rear wheel support parts 4 rearward of the side of the load-carrying platform 2, a front wheel 7 provided via a front wheel support part 6 forward of the back side of the load-carrying platform 2, and a foot tread part provided rearward of the rear side of the load-carrying platform 2. A user treads on the foot tread part to make an assist force generating spring 85 in a spring shrinkage stability state by lowering the foot tread part. The spring shrinkage stability state is released by operating a release lever 9 to make the rear wheels 5 rotate under a restitutive force that the assist force generating spring 85 tends to return to an original state, thereby making the carriage 1 run forward.

    【課題】モータやバッテリ等を搭載することなく簡単にアシストして走行開始時等における作業者の負担を軽減することができるバネ式アシスト付き運搬用台車を提供すること。【解決手段】荷台2と、荷台2の後方側に設けられたハンドル3と、荷台2の裏側の後方側に一対の後輪支持部4を介して設けられた一対の後輪5と、荷台2の裏側の前方側に前輪支持部6を介して設けられた前輪7と、荷台2の裏側の後方側に設けられ、足踏み部を作業者が踏んで下降させることによりアシスト力発生バネ85を伸縮させたバネ収縮安定状態におき、解除レバー9の操作によってバネ収縮安定状態を解除してアシスト力発生バネ85の元に戻ろうとする復元力により後輪5を回転させて台車1を前方へ走行させる。【選択図】図1
