PROBLEM TO BE SOLVED: To provide a lift mechanism which reduces a drive loss when transporting a traveling body, can simplify a device constitution, and transports the traveling body by a power source of the self-travelable traveling body.SOLUTION: In this lift mechanism having a transportation body which is driven by a first gear driven by a drive source possessed by the traveling body when transporting the self-travelable traveling body, and transports the traveling body, the lift mechanism has: a moving mechanism which moves the transportation body on which the traveling body is placed to a vertical direction by power which is transmitted from the drive source, and a counter weight which moves in conjunction with the vertical movement of the transportation body. The moving mechanism has a second gear which is engaged with a first gear, a pinion gear which rotates in conjunction with the second gear, a rack which is engaged with the pinion gear, and extends to the vertical direction, and a one-way gear which rotates in only a constant direction. The one-way gear is engaged with the second gear at a rise of the transportation body, and rotates the second gear to only a rotation direction in which the transportation body is raised.SELECTED DRAWING: Figure 1
