The width of the entrance 8 of the locking groove 7 for locking the support shaft 5 of the roller is smaller than the outer diameter of the support shaft 5, and is formed so that the support shaft 5 of the roller is locked in the locking groove 7. To do. That is, since the roller receives an upward force by pressing the liquid feeding tube, the support shaft 5 is pressed against the entrance 8 of the locking groove 7 by the provision of the locking groove 7, and a part of the supporting shaft 5 is fitted. Then, the roller is securely fixed in this position. If the width of the entrance 8 of the locking groove 7 is larger than the outer diameter of the support shaft and the depth of the locking groove is deep, the support shaft 5 will enter the depth of the locking groove, so that the next tube When trying to release the blockage, it cannot be released easily. If the width of the entrance 8 of the locking groove is too narrow, the support shaft 7 cannot be fixed completely. Therefore, when the depth of the locking groove is large, the width of the entrance 8 of the locking groove is 0.05 to 0.4 of the outer diameter of the support shaft 5 of the roller.
It is preferably in the range of 9. Within this range, the support shaft 5 of the roller is securely fixed, and the fixation can be easily released.

The width of the entrance 8 of the locking groove 7 for locking the support shaft 5 of the roller is larger than the outer diameter of the support shaft 5, The groove depth of the stop groove 7 is formed within the range of 0.05 to 0.49 of the outer diameter of the support shaft 5. The roller receives an upward force from the liquid feeding tube by pressing the liquid feeding tube, the supporting shaft 5 of the roller abuts against the end portion 11 of the locking groove, and the supporting shaft 5 of the roller receives the locking groove 7 Locked in. The support shaft 5 of the roller has an end portion 11 of the locking groove.
Although it can move in the locking groove 7 while being in contact with the
Is formed at a position where the liquid supply tube can be closed, so that the liquid supply stopped state can be reliably maintained even if the support shaft 5 moves in the locking groove 7. At this time, if the depth of the locking groove 7 is too shallow, there is a possibility that the support shaft 5 once locked may come off the locking groove 7 due to the elastic reaction force of the liquid feeding tube. If the depth of the locking groove 7 is too deep, the support shaft 5 goes into the depth of the locking groove 7 and cannot be easily released the next time the tube is to be unblocked. Therefore, the depth of the locking groove 7 is appropriately within the range of 0.5 to 0.49 of the outer diameter of the roller support shaft 5.
