When the drip tube 7 is sandwiched and not positioned by the positioning means 8, when the reduction block 83 is pushed to compress the compression spring 85 and the pair of rubber blocks 86 are separated, the drip tube 7 is pulled outward to the lower chamber. It is stored inside 1b. As a result, by adjusting the length of the portion of the drip tube 7 on the outside of the shale 1,
The exposed portion of the drip tube 7 on the outside of the shale 1 is too long or too short to interfere with the injection of nutrient solution in the nutrition bag. When adjusted to an appropriate length, the pressure on the reduction block 83 is released, and the pair of rubber blocks 86 sandwich and position the drip tube 7 by the elastic force of the compression spring 85. A chipped groove is provided in the rubber block 86. The width of the pair of chipped grooves is smaller than the width of the drip tube 7, and when the drip tube 7 is sandwiched, the drip tube 7 is simply sandwiched from both sides along the width direction, and the drip solution in the nutrition bag is not sandwiched from the central part. To facilitate the flow of. It does not interfere with the drip droplet ejection in the drip tube 7 due to an excessive holding force or a too large holding area.

The above are only preferable examples of the present invention, and the present invention is not limited to these examples.
