く。Reference numeral 18 denotes a rotation stop plate of the support shaft 7 having a hole 19 at the center on the outer surface of the one side plate 11 of the case 6 for engaging with the engagement portion 16 of the support shaft 7. The leaf springs 20 are attached to both sides of the back surface facing the one side plate 11 of the case 6 so as to be movable in parallel and far relative to the one side plate 11 of the case 6. 21 is a rotation stopper plate 18 and one side plate of the case 6
Mounting brackets for supporting both sides so as to be movable in parallel and far relative to 11, which are fixed to the case 6 at both ends with screws 22. In the state where the rotation stopper plate 18 is separated from the one side plate 11 of the case 6, the central hole portion 19 engages with the engaging portion 16 of the support shaft 7 so that the support shaft 7 is rotated by the urging force of the mainspring 8. In the state in which it is stopped and is close to the one side plate 11 of the case 6, the central hole 19 is the engaging portion 16 of the support shaft 7.
Is configured to be disengaged from. As described above, the reason why the central hole 19 of the rotation stopping plate 18 is engaged with the engaging portion 16 of the support shaft 7 is to stop the rotation of the support shaft 7 and store the force in the mainspring 8. . By the way, when adjusting the accumulating force of the mainspring 8 according to the sliding doors 1 having different weights, a jig such as a screwdriver is engaged with the minus groove 17 of the head 12 of the support shaft 7 to rotate it. The stopper plate 18 is pushed against the force of the leaf spring 20 so that the stopper plate 18 is brought close to the one side plate 11 of the case 6 to disengage the central hole portion 19 from the engagement portion 16 of the support shaft 7,
Adjustment can be performed by rotating the support shaft 7 clockwise or counterclockwise with a jig such as a screwdriver. After the adjustment, the hand is removed from the anti-rotation plate 18, and the central hole 19 is engaged with the engaging portion 16 of the support shaft 7.
