The present invention relates to a key wearing tool in which the length of a band can be easily adjusted in accordance with the size of a user′s wrist or ankle. The key wearing tool according to the present invention includes: a main body to which a key is attached; and the band coupled with the main body to form a closed-loop shape with the main body and formed of a material capable of elastic deformation. One end of the band is fixedly coupled with the main body and the other end of the band is inserted into the main body. A plurality of protrusions are formed in the band along a length direction of the band from the other end. Elastic engaging means is provided in the main body to be engaged with one or more of the protrusions. Each of the protrusions has a first surface elastically deforming the engaging means during a movement of the other end of the band for insertion into the main body such that the engaging means and the protrusion are not engaged with each other and a second surface engaged with the engaging means and preventing a movement of the band when the other end of the band is moved for escape from the main body. When the other end of the band is subjected to a predetermined force or more in the direction of escape from the main body, elastic deformation is performed such that the engagement between the second surface and the engaging means is released. |
