５に衝合する。 FIG. 1 shows a state in which the cord 24 is wound up. When the cord 24 is pulled out, the reel 2 rotates in the direction of the arrow, and the stopper lever 12 is rotated so that its center is long with respect to the main shaft 14. It is located at a position shifted to one side of the hole 13, and the stopper lever 12
The central protrusion 12C is caused by the stopper spring 15.
Since the stopper lever 12 is slidably and rotatably pivoted to the reel in a constant pressure contact state, the claw 12b at the tip of one side of the stopper lever 12 is attached to the main shaft 1 as shown in FIG.
4, the entire position is shifted to one side (left side) along the elongated hole 13, and the stopper lever rotates with the claw 12b at the tip of one side abutting against the peripheral wall 5 of the case 1. In this state, the claw 12b at the tip of one side of the stopper lever 12 presses the gentle slope 6 of the locking protrusion 8 of the case 1, and due to this pressure, the entire position of the stopper lever 12 is shifted in the opposite direction from the front. In this state, the stopper lever 12 is moved over the claw 12b at the tip of one side, then the claw 12a at the tip of the other side over the locking protrusion 8, and at the same time the stopper lever 12 is moved over the locking projection 8. Since the center of the lever 12 is offset to one side of the elongated hole 13 with respect to the support shaft 14, the stopper spring 1
Due to the elasticity of the stopper lever 12, the claw 12a at the tip of one side of the stopper lever 12 rotates as a fulcrum with the support shaft 14.
collides with the peripheral wall 5 of the case 1. In this state, the stopper lever 12 repeats this operation every rotation to continue rotating and sliding until it reaches an arbitrary pull-out position. (Fig. 7) Next, when the cord 24 reaches the desired length, when the cord is loosened, the cord 24 is wound up by the restoring force of the spring 3, and the reel 2 is moved as indicated by the dotted line arrow opposite to the previous one. At the same time, the claw 12a at the tip of one side of the stopper lever 12 engages the locking protrusion 8.
engages with the steep slope 7 of the main shaft 14 to shift the entire position to one side (to the right) with respect to the main shaft 14. As a result, the claw 12a at the tip of one side of the stopper lever 12 abuts against the peripheral wall 5 of the recess 4.

る。 At this time, the tip of the main shaft 14 engages with the seat 13a provided at one end of the elongated hole 13 of the stopper lever 12, stopping the rotation of the reel 2 and stopping winding of the cord. (Fig. 8) To start winding again, pull out the cord 24 again, and as the reel 2 rotates, the claw 12 at the end of one side of the stopper lever 12 will rotate.
At the same time as a leaves the steep slope 7 with which it is engaged,
Due to the elasticity of the stopper spring 15 pressing the central protrusion 12C of the stopper lever 12, the stopper lever 12 is returned to the peripheral wall 5 side of the case 1.
The direction of the case 1 is changed, and the claw 12b at the tip of one side is attached to the case 1.
It collides with the peripheral wall 5 of , resulting in a state as shown in Fig. 9,
Winding of the cord continues in this state.

る。 Since this invention has the above-mentioned configuration, the spindle is located at one end of the long hole of the stopper lever.
When the cord is pulled out with one end of the arcuate surface of the stopper lever, which is the other end of the elongated hole, being biased against the circumferential wall of the circular recess by the spring, one end of the arcuate surface of the stopper lever touches the case. The stopper lever slides and rotates to position the support shaft at the other end of the elongated hole. The other end of the arcuate surface of the stopper lever, which is one end of the elongated hole, is biased by the spring against the circumferential wall of the circular recess, and in this state, this action is repeated every rotation to pull out the cord to the desired length. When the cord is loosened when it reaches the desired length, the cord is wound up by the rotation of the reel that is biased in one direction, and the other end of the arched surface of the stopper lever moves to the steep slope of the locking protrusion. At the same time, the stopper lever slides and rotates so that the spindle is positioned at one end of the elongated hole, and when the cord is pulled out to wind it from this state, the stopper lever slides and rotates. The other end surface of the arcuate surface of the stopper lever that is released from the steep slope of the stopper lever is separated from the peripheral wall of the circular recess by the spring, and conversely, one end surface of the arcuate surface of the stopper lever abuts against the peripheral wall. The cord is energized and the winding of the cord is completed in this state, and as mentioned above, the cord can be reliably taken in and out with an extremely simple configuration and a small number of parts, and it can be stopped at the desired length. Moreover, it has excellent effects such as being less prone to failure and being able to be miniaturized.
