BACKGROUND OF THE INVENTION The present invention relates to a guide member for a greenhouse vinyl sheet opening / closing device which winds and rewinds a vinyl sheet forming a greenhouse side wall to open and close to control the temperature or ventilate the greenhouse. About.

[0002]

2. Description of the Related Art Conventionally, it is necessary to wind up a vinyl sheet forming a side wall of a greenhouse along a shape of a greenhouse from a lower end thereof with a winding rod. As a guide member for moving the guide rod, for example, Japanese Utility Model Publication No. 59-3428
No. 6 discloses the following structure.

[0003] That is, a drive shaft connected to one end of the winding rod, a ratchet pivotally fixed to the drive shaft,
A handle for rotating the drive shaft, a pair of two side plates rotatably supported on the drive shaft so as to sandwich the ratchet, and a rotatable shaft rotatably provided by a pivot pin fixed between the side plates. A detent that is supported and its tip is provided so as to mesh with the ratchet claw, a stopper pin for suppressing rotation of the detent, and a pivot pin fixed to a key point between both side plates so as to be rotatable and rotatable. The driving device includes a plurality of cylindrical guide rollers that are supported in parallel, and a guide pipe that is closely inserted between the guide rollers and supports and guides the driving device.

When the handle is rotated, the winding rod rewinds and rewinds the vinyl sheet, and the guide roller moves up or down along the guide pipe.

[0005]

However, in the conventional guide member, since the guide roller is formed in a cylindrical shape, for example, when one end of the vinyl sheet is lately wound during ascending, a lateral twist is generated. Sometimes. in this case,
Since the guide roller is rotatably supported by a shaft pin that is disposed across a pair of two side plates, the upper edge or the lower edge of the side plate comes into contact with the guide pipe, so-called biting occurs, and the guide member is lifted. There is a problem that the downward movement stops.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and can open and close a vinyl sheet in a greenhouse which can prevent the occurrence of biting on a guide pipe even if lateral twisting occurs due to a delay in winding the vinyl sheet. An object is to provide a guide member for an apparatus.
