The locking pin 11 is expanded in diameter when the enlarged diameter head 12 is inserted from the large diameter hole portion 25a of the locking pin insertion / removal support hole 25 and then relatively moved to the small diameter groove portion 25b side. Since the head portion 12 cannot pass through the small-diameter groove portion 25b, the wall surface of the support wall 21 around the small-diameter groove portion 25b and the enlarged-diameter head portion 12 are engaged with each other to prevent the head portion 12 from coming off. On the inner surface of the contour wall 22,
Expanding head 1 of locking pin 11 located in small-diameter groove 25b
A movement preventing wall 26 is formed so as to abut the peripheral edge of 2.

The opening / closing center column 24 is provided at a position that is perpendicular to the direction of extension of the small-diameter groove portion 25b toward the large-diameter hole portion 25a and has a rectangular cross section.
The pair of surfaces on the long side constitutes a closed position holding surface 24a parallel to the support wall 21, and the pair of surfaces on the short side orthogonal to the pair constitutes an open position holding surface 24b. Width of the pair of closed position holding surfaces 24a (distance between the pair of open position holding surfaces 24b)

It is provided with a cylindrical stopper wall 33 provided in the vicinity of a connection base portion with 31. The stopper wall 33 includes the enlarged diameter head 12 of the locking pin 11 fitted in the small-diameter groove portion 25b of the locking pin insertion / removal support hole 25 when the retaining lid 30 is closed in the contour wall 22. It is held between the anti-movement wall 26 of 20 to prevent its movement.

A pair of ridges 31a and 31b corresponding to the width of the closed position holding surface 24a of the opening / closing center column 24 are provided on the inner surface of the end of the outer substrate 31 on the side of the opening / closing center column 24. The inner elastic leg 32 is provided with a ridge 32a facing the ridge 31a. The inner elastic leg 32 can be opened and closed with respect to the outer substrate portion 31 by its own elasticity,
Further, even when the outer substrate portion 31 is closed inside the contour wall 22, elasticity is provided so as to be in close contact with the closed position holding surface 24a of the opening / closing center support 24. Further, at the time of assembly, by opening the inner elastic leg 32, the protrusion 31 of the outer substrate portion 31
Between a and 31b and the protrusion 32a of the inner elastic leg 32,
The opening / closing center column 24 can be sandwiched. Reference numeral 35 is a nail hook recess.

The strap attaching / detaching tool 100 having the above structure is
As shown in FIG. 3, in the state where the stopper lid 30 is opened,
The outer substrate portion 31 and the inner elastic leg 32 come into contact with the pair of open position holding surfaces 24b of the opening / closing center column 24. Since the distance A between the pair of open position holding surfaces 24b is larger than the distance B between the pair of closed position holding surfaces 24a, the inner elastic legs 32 are largely elastically deformed and the retaining lid 30 is held at the open position. Therefore, in this state, the enlarged diameter head portion 12 of the locking pin 11 can be inserted into the large diameter hole portion 25a of the locking pin insertion / removal support hole 25 and relatively slid toward the small diameter groove portion 25b side. Then, when the retaining lid 30 is closed with the small-diameter shaft portion 13 of the locking pin 11 positioned at the lower end of the small-diameter groove portion 25b, the inner elastic leg 32 is formed.
Is opened to the maximum when the cross-section diagonal line of the opening / closing center column 24 is crossed, and then becomes linear due to its elastic restoring force. Therefore, as shown in FIG. 2, the outer substrate portion 31 and the inner elastic legs 32 are formed.
The inner surface of the pair of closed position holding surfaces 24a of the opening / closing center support 24
Will be in contact with. In this state, the inner elastic leg 32 is the most stable state, and at this time, the stopper wall 33 of the retaining lid 30 and the movement preventing wall 2 of the hanging body 20.
The expanding head 12 of the locking pin 11 is sandwiched between the carrying item 10 and the holding pin 6, and the carrying item 10 and the strap attaching / detaching tool 100 do not move relative to each other. That is, the movement-preventing wall 2 through the enlarged-diameter head 12
The downward force applied to 6 is received by the strap S, and the upward force applied to the retaining lid body 30 via the enlarged diameter head 12 and the stopper wall 33 is applied to the protrusion 31b of the retaining lid body 30.
It can be received by the engagement of the opening and closing center column 24.

As described above, the strap attaching / detaching device 100 of the present invention does not use a metal material such as a metal spring (leaf spring) which is a separate member, and the suspension main body 20 made of a molded product of a resin material and the retaining lid. The greatest feature is that it is composed of only the body 30. In the strap attaching / detaching tool 100 of the present invention,
The spring property of the inner elastic leg 32 of the retaining lid 30 is an important element, and if this spring property is weak, the retaining lid 30 may be inadvertently opened in the closed state. If the removal prevention lid 30 is opened carelessly, the locking pin 11 may come out of the locking pin insertion / removal support hole 25 due to vibration or the like, and the portable article 10 may drop.
