PROBLEM TO BE SOLVED: To provide a plant cultivation apparatus keeping the plant cultivation container horizontal even if omitting a shaft for connecting a pair of sprockets.SOLUTION: The plant cultivation apparatus 1 includes a pair of counters 60A and 60B which measure the timing of their contact with hooking bars 32a set on both the ends of a support bar 32, or the timing of their release of contact at the same height as the installation surface of the apparatus, and a horizontal-retaining means 70 which adjusts the rotating speed of motors 20A and 20B which rotate chains 50A and 50B when the timings have a lag equal to or above a certain level in timing, so as to correct the inclination of the support bar and keep a plant cultivation container 30 horizontal.COPYRIGHT: (C)2010,JPO&INPIT【課題】一対のスプロケットの間を繋ぐシャフトを省略しても、植物栽培容器を水平に保つことができる植物栽培装置を提供する。【解決手段】植物栽培装置1の設置面から同じ高さの位置に、支持棒32の両端部に設けられた引っ掛け棒32aと接触するタイミング、または接触が解除されるタイミングを測定する一対のカウンタ60A、60Bと、タイミングに一定以上のずれがある場合にチェーン50A、50Bを回転させるモータ20A、20Bの回転速度を調整する水平保持手段70を設け、支持棒の傾きを是正して植物栽培容器30を水平に保つ。【選択図】図1
