A detachable structure includes a toy and a detaching tool. The toy comprises a first part and a second part engaged with the first part. The detaching tool comprises a presser and elastic holders with holding parts that are at any one of a holding position and a holding releasable position. The first part is elastic and comprises an elastic engaging hook that is at any one of an engaged position and an engagement releasing position. The second part engages with the first part when the second part is brought to the first part in a certain direction so that the second part slidably contacts the first part to move the elastic engaging hook to the engagement releasing position and then further to the engaged position.
