<p>PROBLEM TO BE SOLVED: To provide a folding-type transport carriage in which a lock mechanism is simply constituted by few component numbers, and which can be easily assembled and can be manufactured inexpensively.SOLUTION: A folding-type transport carriage equipped with a folding operation lock mechanism in which an operation part 6 provided with an inclination long hole 9 penetrating therethrough in a lateral direction is so provided as to be vertically movable in an open hole 5 provided on the front side of a bottom plate part 1, and a lock rod 12 is so provided as to be inserted into the inclination long hole 9 of the operation part 6 disposed in the open hole 5 and a laterally long parallel guide hole 11 of a reinforcement plate part 10 provided on the bottom plate part 1. When the operation part 6 is operated for downward action, the lock rod 12 is horizontally moved along said laterally long horizontal guide hole 11 and is engaged with a lock rod engagement part 13 so as to be placed in a lock state. When the operation part 6 is operated for upward action, the lock rod 12 is horizontally moved in a front-back direction along said laterally long horizontal guide hole 11 and is separated from the lock rod engagement part 13 so as to be put in a lock release state.</p> |
