Fixed to the outer casing, an outer casing having an opening formed at the upper end, a split-type locking piece housed in the outer casing and having a tapered surface complementary to the tapered surface on the outer surface, An elastic element that is held between a spring receiving piece and the split locking piece and always urges the split locking piece upward; and the elastic element for connecting the cord body through the opening of the outer casing. When the push-in force is pushed against the action of the elastic member, the split-type locking piece is expanded outward, the cord body is inserted into the outer casing, and the wedge action is performed when the push-in force is made smaller than the force of the elastic element. Causes the cord to move in the direction opposite to the pushing direction. It is provided with a cord locking device that is fixed, the inner diameter of which is inserted through the cord, the outer diameter is smaller than the diameter of the opening, and the inner diameter of the expanded split piece locking piece. Also, there is a cord locking device formed by combining a take-out tool having an enlarged split tubular shaft portion.

The casing 2 is provided with an opening 1 at the upper end on the outer side of a substantially cylindrical shape, and the inner surface is a tapered surface that narrows upward. Inside the outer casing 2, there are housed cylindrical half-divided locking pieces 6 and 6 having two thick lower portions. The locking pieces 6 and 6 define an inner hole corresponding to a size for receiving the cord body 5 having a predetermined uniform diameter, and inside the inner hole, several pieces are alternately arranged in a direction crossing the cord body 5. The outer surface of the half split locking piece is the outer casing 2
The taper surface is almost complementary to the taper surface of. Therefore, when the two locking pieces 6 and 6 are combined, a cylindrical trapezoidal cross section having a thick lower portion is formed. Below the locking pieces 6, 6 inside the outer casing 2, a thin disc-shaped spring holding piece 4 having a central hole large enough to pass the cord 5 is press-fitted from the lower opening of the outer casing 2. The compression spring 3 is fixedly supported between the spring holding piece and the locking pieces 6 and 6 in a pressed state. When the cord body 5 is inserted through the opening 1 at the upper end,
The locking pieces 6 and 6 are pushed down against the action of the compression spring 3, and the force for pushing the cord 5 acts on the half-shaped locking piece 6 to generate a radial component force. Can be spread in any direction.
Therefore, the cord body 5 descends through between the locking pieces 6 and 6 and is inserted into the outer casing 2. The cord body 5 is free to move downward in FIG. 1a, but upwardly between the locking pieces 6, 6 by the wedge action of moving the locking piece 6 toward the opening 1 by the compression spring 3. Be detained.
Therefore, the cord body 5 is completely locked in one direction (upward direction in this example).

りも大きな外径の半円筒状の軸部２４とを備えている。As described above, the cord body 5 can be pulled out downward, but cannot be pulled out upward. Therefore, if the upper end of the cord 5 is fixed at the upper end to, for example, the winding device, the wall, or the ceiling, it cannot be taken out from the outer casing 2. Even in such a case, in order to enable the cord body 5 to be pulled out from the opening 10 at the upper end, the take-out tool shown in FIGS. 2a and 2b is used. The take-out tool 20 has a disk 21 having a radial opening 23 for inserting the cord 5 from the outside and a central hole 22 communicating with this, and the diameter and the inner diameter of the central hole 22 are the same. It is provided with a semi-cylindrical shaft portion 24 that is small and has an outer diameter larger than the diameter of the inner hole of the locking pieces 6 and 6 when it is widened most.

When the piece 6 is pressed downward, the locking piece 6 descends against the compression spring 3 and is expanded outward in the radial direction, so that the pressing force on the cord 5 is removed, so that the locking piece 6 moves upward through the opening 1. The cord body 5 can be pulled out.

Even if there is no mechanism, even if it is present, it is not incorporated into the inside of the locking tool and exposed to the outside, but it is separate from the locking tool, so unlocking by accidental operation is prevented . Further, the cord can be locked up to near the breaking strength of itself, and is made of a wide range of materials such as steel wire and synthetic resin cord. Therefore, in construction or work using a cord body made of various materials, there are advantages such as improvement in mounting safety and work efficiency.
