To make it possible chiefly to lock a free wheel without spending time and effort.SOLUTION: In a component conveyance truck 1, a first steering frame 4 having a pair of left and right free wheels 3 which are horizontally turnable and a second steering frame 6 having a pair of left and right stationery wheels 5 are so located below a truck body 2 as to be separated front and rear in a direction x of travel and are respectively supported so as to be horizontally rotatable, and the first steering frame 4 and the second steering frame 6 are so connected by a steering link 7 as to be rotated in directions opposite to each other, thereby enabling four-wheel steering. A lock mechanism 51, which can perform locking and unlocking of horizontal turning of the left and right free wheels 3 individually, is provided, and further, left and right independent lock operation mechanisms 52, which can individually operate each lock mechanism 51 of the left and right free wheels 3, are provided in the first steering frame 4.SELECTED DRAWING: Figure 7

    【課題】主に、手間をかけずに自由輪をロックし得るようにする。【解決手段】水平旋回可能な左右一対の自由輪3を有する第一の操舵フレーム4と、左右一対の固定輪5を有する第二の操舵フレーム6とを、台車本体2の下部に、進行方向xの前後に離して配置すると共に、それぞれ水平回動自在に支持し、第一の操舵フレーム4および第二の操舵フレーム6を互いに逆方向に回動するように操舵リンク7で連結して四輪操舵可能とした部品搬送台車1に関する。左右の自由輪3の水平旋回を個別にロックおよびロック解除可能なロック機構51を設けると共に、第一の操舵フレーム4に、左右の自由輪3の各ロック機構51を個別に操作可能なロック操作機構52を左右独立して設けるようにする。【選択図】図7
