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

    【課題】走行体を搬送する際に駆動ロスを低減し、かつ装置構成を簡略化することができる、自走可能な走行体の動力源によって走行体を搬送する昇降機構を提供すること。【解決手段】本発明は、自走式の走行体を搬送する際に走行体が有する駆動源によって駆動される第一ギヤによって駆動されて走行体を搬送する搬送体を有する昇降機構であって、走行体が載置された搬送体を駆動源から伝達される動力によって上下方向に移動させる移動機構と、搬送体の上下動に連動して移動するカウンターウェイトと、を有し移動機構は、第一ギヤと噛合する第二ギヤと、第二ギヤに連動して回転するピニオンギヤと、ピニオンギヤに噛合して上下方向に延在するラックと、一定方向にのみ回転するワンウェイギヤと、を有し、ワンウェイギヤは、搬送体の上昇時に第二ギヤと噛合し、搬送体を上昇させる回転方向にのみ第二ギヤを回転させる。【選択図】図1
