As a result, the other end of the elastic string 1 is fitted into the insertion portion 121 of the body 12 and fixedly coupled to the coupling portion 212 of the pillar 21 via the accommodation space 111.

More specifically, the 'attachment object' is a shoe, the 'elastic string' corresponds to a shoelace,

In particular, the 'attachment object' is not limited to shoes, various items that require an operation such as winding or unwinding the elastic string in the article is required, the elastic string may be applicable,

Eventually, the two strands exposed by being tied to the shoe which is the attachment object 2 become two elastic strings 1.

The two elastic strings 1 are fixed at each other end to each coupling portion 212.

When the catching portion 231 is caught by the lower corresponding catching portion 115

When the ratchet 113 and the corresponding ratchet 233a, the sub ratchet 232a and the corresponding subratchet 233b are engaged with each other, the holding member 233 of the rotary unit 20 rotates in one direction. As the sub ratchet 232a is caught by the corresponding sub ratchet 233b,

The pillar 21, the lower body 22, and the plate 232, which form a bundle, may also be rotated in one direction, so that the corresponding ratchet 221 may move over the ratchet 113. As a result, two elastic strings 1 are stretched and wound around the pillar body 21 (see [a] and [b] of FIG. 3).

When the catching portion 231 is caught by the upper corresponding catching portion 114, that is, by holding the holding member 233 and pulling it out of the housing 10, the catching portion 231 catches the upper corresponding catching portion. When we catch part 114

Each of the ratchets 113 and the corresponding ratchets 233a, the sub ratchets 232a, and the corresponding subratchets 233b which are engaged with each other are disengaged from each other, forming the bundle 21 and the lower part. As the body 22 and the plate 232 are forcibly rotated in the other direction by the elastic force of the wound elastic string 1, the elastic string 1 is automatically released from the pillar 21. In this case, unwinding of the elastic string 1 means that the state is changed from a state in which the elastic string 1 is stretched to a state in which the elastic string is loosely wound.

Therefore, by wrapping the two strands (two elastic string) of the shoelaces fixed to the respective coupling portion 212 to prevent the peeling when wearing the shoes, on the contrary by loosely loosening it is easy to take off or wear shoes.
