  However, in the conventional case, the rope member for preventing the fall including the spiral cord protrudes outward from the tool body over the entire length, so that the tool body is held on the tool sack or tool retaining ring of the waist belt. When the operator is moving around or during work, the central part in the longitudinal direction of the cord member is curved with a large arc and is in a state of hanging downward. There is a problem that it becomes easy to get caught in the work, which disturbs the work. In addition, there is a problem that a long rope member becomes an obstacle when being held or taken out by a tool sack or a tool retaining ring.

  In view of the above problems, the present invention can prevent a rope member for a fall prevention tool from being caught on a projection or the like when the tool body is held on a waist belt or the like. An object of the present invention is to provide a tool that can be easily inserted into and removed from the retaining ring.

Specific means for solving the problems in the present invention are as follows.

It is stored in the storage unit 6A so that it can be fed out from the storage unit 6A.
The second rope portion 8 is constituted by a chain 8A formed by flexibly connecting a large number of ring bodies 25 made of metal or synthetic resin, and is formed longer than the lengths of the spiral cord 7A and the storage portion 6A in a reduced state. ing.

The ring body 25 at the base end portion of the second ridge portion 8 is connected to the distal end loop portion 20 of the first ridge portion 7 in a chain shape, whereby the base portion of the second ridge portion 8 is connected to the first ridge portion 7. The second rope portion 8 is protruded outward from the storage portion 6A.
A connecting body 29 that is detachably connected to the operator side via a connecting ring 27 is provided at the distal end portion of the second rope portion 8. The connection ring 27 is connected to the ring body 25 at the distal end portion of the second ridge portion 8 in a chain shape, and is connected to the distal end portion of the second ridge portion 8.

  The connection body 29 is constituted by a metal fitting called a so-called eggplant. The connection body 29 includes a tool body 32 having a hook 30 and a closing piece 31 for closing the opening of the hook 30 so as to be openable and closable. The main body 32 includes a connecting ring 34 that is rotatably supported around an attachment shaft, and the closing piece 31 is formed in a ring shape by an elastic wire and closes the opening of the hook 30 (in the direction of arrow a in FIG. 1). Both end portions are displaced from each other and engaged with the tool body 32 so as to generate a biasing force.

  The connection ring 34 of the connection body 29 is connected to the connection ring 27 in a chain shape, and the connection body 29 is connected to the distal end portion of the second strip portion 8 via the connection ring 27. For example, as shown in FIG. 3, the connecting body 29 is connected to a belt loop 38 such as an operator's work pants, and thereby the second rope portion 8 is detachably connected to the operator side. A waist belt 35 is attached to the operator side through a belt loop 38 such as a worker's work pants, and a tool holding bracket 36 is attached to the waist belt 35.

As shown in FIG. 4, the tool holding bracket 36 includes a support plate 39 disposed on the outer surface side of the waist belt 35 and an engagement plate 40 disposed on the inner surface side of the waist belt 35. A retaining ring 37 protrudes horizontally.
