[0013]

According to the rope tightening fitting of the present invention,
A substantially rectangular annular frame body 2 and a slidable rope holding body 1 provided on one side of the annular frame body 2,
The rope holding body 1 has a slide guide portion 1a and an S-shaped portion.
Since it is provided with the character-shaped friction applying portions 1b and 1c, the step between the rope holding body 1 and the friction applying body 2a in the rope tightening direction is reduced as shown in FIGS. By reducing the rope friction, the rope A can be tightened with a smaller force than before, and the rope A is later applied between the friction imparting body 2a and the friction imparting portion 1b and between the friction imparting portion 1b and the friction imparting portion 1b. If it is sandwiched between the portion 1c and the portion 1c, there is an effect that a large friction is generated in the tightening direction and the anti-tightening direction of the rope A and the rope A is not loosened.

Further, since one end portion of the annular frame 4 is bent and projected at about 90 degrees, and substantially S-shaped friction imparting portions 4a, 4b and 4c are provided on the bent and projected portion. The rope A is sandwiched by the rope holding body 5 and the friction imparting portions 4a, 4b, 4c in a corrugated shape, and the rope holding body 5 does not move to loosen the rope. Therefore, the friction with respect to the return force of the rope in the related art does not affect the rope locking member 11
The rope bending along the part of the rope locking member 12, and the rope locking member 11 and the rope locking member 12
Although the rope was rubbed between the rope and the rope, in the present invention, friction is applied to the rope A by the friction applying portions 4a, 4b and 4c of the bent protruding portion and the rope holding body 5. It has the effect of reliably stopping the rope.

When the rope is loosened, the rope holding member 1 of the rope locking member is used as compared with the conventional rope tightening fitting.
Since the step between the and the friction imparting body 2a can be made small, there is an effect that it can be easily loosened by shifting the rope of the S-shaped portion sideways and removing it, and the structure is simple and the cost is low. And so on.
