To provide a dolly assist mechanism that allows a dolly to start moving easily and linearly when making the dolly with a material or cargo mounted thereon travel by man power.SOLUTION: A dolly assist mechanism comprises: a tilting frame 2 which is provided on a lower surface side of a rear deck 91 of a dolly 9 so as to be capable of tilting along a front-rear direction in which the dolly 9 travels; a pedal 3 supported on a rear part of the tilting frame 2 rotatably; assist drive wheels 6 which are rotatably supported on a front part of the tilting frame 2 so as to be rotatable along the front-rear direction and which float from a travel plane G of the dolly 9 and land on the travel plane G by tilting of the tilting frame 2; and a power transmission mechanism 4 for transmitting rotation operation force of the pedal 3 as rolling force of the assist drive wheels 6. The assist drive wheels 6 rotate forward in response to rotation operation of the pedal 3 while a front side of the tilting frame 2 being tilted downward and the assist drive wheels 6 being in contact with the travel plane G.SELECTED DRAWING: Figure 1

    【課題】資材や荷物を積載した台車を人力で走行させる際に台車を容易に且つ真っ直ぐに動き出させることを可能にする。【解決手段】台車9の荷台91の下面側に台車9が走行する前後方向に沿って傾動可能に設けられる傾動フレーム2と、傾動フレーム2の後部に回動可能に支持されるペダル3と、傾動フレーム2の前部に前後方向に沿って回転可能に支持されるとともに傾動フレーム2が傾動することによって台車9の走行面Gから浮いたり走行面Gに接地したりする助勢駆動車輪6と、ペダル3の回動操作力を助勢駆動車輪6の転動力として伝達する動力伝達機構4と、を備え、傾動フレーム2の前側が下向きに傾斜して助勢駆動車輪6が走行面Gに接地している状態でペダル3が回動操作されることによって助勢駆動車輪6が前転する。【選択図】図1
