PROBLEM TO BE SOLVED: To provide a film winding/unwinding control device having a trough opening adjustment casing without being protruded with respect to a deceleration casing, thereby to achieve low costs and provide benefits such as ease of assembly, simplicity of wiring, and improvement in workability for greenhouse farmers or manufacturers.SOLUTION: There is provided the winding/unwinding control device of film B of a house A, comprising: a transmission unit for decelerating rotation of an output shaft of a motor and changing a rotational force transmitting direction； a winding/unwinding drive shaft of the transmission unit having a support portion of the winding/unwinding shaft and a rotating body； a slider disposed on a rotating shaft supporting a rotated body connected to the rotating body； and a switch that regulates a forward limit and a retreat limit of the slider. The deceleration casing accommodating the transmission unit and the rotating body is provided adjacent to an output shaft side of a motor casing. The deceleration casing and the motor casing additionally include the trough opening adjustment casing.SELECTED DRAWING: Figure 1【課題】減速ケーシングに対して、谷部開口調整部ケーシングが突出せず、組立ての容易化、配線の簡便化、並びに作業性の向上化を図れれ、ハウス農家、又は製造業者に、恩恵と低コストが図れるフイルムの巻取り巻戻し制御装置を提供する。【解決手段】モータの出力軸の回転を減速し、かつ回転力伝達方向を変える伝達装置と、巻取り巻戻し軸の支持用支持部、及び回転体とを有し、伝達装置の巻取り巻戻し駆動軸と、回転体に連繋する被回転体を支持する回転軸に設けたスライダと、スライダの前進限と後退限とを規制するスイッチでなるハウスＡのフイルムＢの巻取り巻戻し制御装置を構成し、モータケーシングの出力軸側に隣設して、伝達装置、及び回転体を収容した減速ケーシングを設け、減速ケーシングとモータケーシングに、谷部開口調整部ケーシングを添設する構成。【選択図】図１
