PROBLEM TO BE SOLVED: To make a stopper easy to be engaged and difficult to be detached, and to allow one-touch attachment, in a one-touch button which comprises a button body and the stopper and in which the stopper is engaged with the button body.SOLUTION: A one-touch button 40 comprises a button body 10 and a stopper 20, the center of the button body 10 is formed with an engagement hole 11, and the periphery thereof is formed with hollow holes 14. The stopper 20 includes a locking part 22 in the tip of a columnar part 21. When pushing the locking part 22 into the engagement hole 11, the engagement hole 11 is easily elastically deformed by the hollow holes 14 around the engagement hole 11, and a diameter is enlarged, so that engagement of the locking part 22 is facilitated and one-touch attachment is allowed. Because the diameter of the engagement hole 11 is reduced to an original hole diameter after the diameter of the engagement hole 11 is enlarged, the one-touch button 40 becomes difficult to be detached by the certain engagement. |
