<p><P>PROBLEM TO BE SOLVED: To allow a belt not to be loosed inadvertently since engagement and holding of the same is secured in a buckle. <P>SOLUTION: The buckle allows a female buckle and a male buckle 18 to be fitted in each other. An engagement part 26 is arranged across a first insertion hole 28 at an end on a fitting protrusion 24 side of a base 25 in the male buckle 18. A hook part 27 is arranged across a second insertion hole 29 on a side opposite to the first insertion hole 28 with respect to the engagement part 26. A free end 13a of the double belt 13 wound around the hook part 27 passes through the second insertion hole 29, and is overlapped on a base end side part 13b, and passes through the first insertion hole 28, and winds the engagement part 26. A protruding part 30 capable of abutting on a double belt 13 is formed at an end 24c of a fitting protrusion 24. Even when a force that pulls downward or in a lateral direction is applied to the base end side part 13b of the double belt 13 wound around the engagement part 26, the double belt 13 is not loosed since a pressing force F is generated from the same to the engagement part 26. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
