PROBLEM TO BE SOLVED: To provide a carrying truck excellent in operability and usability, in which folding operation of a handle or braking operation can be smoothly performed while simplifying the structure of a handle part by effectively utilizing a strut or the like of the handle foldably disposed at one end of a platform to dispose a brake mechanism.SOLUTION: The carrying truck includes an operation lever, a connecting rod fitted into the strut of the handle, and the brake mechanism including a brake rod biased by a spring so that a brake part regularly presses the outer circumferential surface of a fixed wheel. When the operation lever is not operated, the brake part is pressed onto the outer circumferential surface of the fixed wheel to arrest the rotation of the fixed brake. When the operation lever is operated, the brake separates from the fixed wheel against the biasing force of the biasing member to allow the fixed wheel to rotate, and also rotates the handle in a folding direction, whereby the operation lever and the connecting rod are folded on the platform integrally with the handle. |
