PROBLEM TO BE SOLVED: To provide a diaper auxiliary tool which is a separate body from a diaper and enables pulling an optional place of a diaper, in view of the fact that a wearer can easily move and a diaper is hardly shifted by using two-stage fastening tapes and crossing tensile force, but due to that a diaper having two-stage fastening tapes is expensive, the diaper having two-stage fastening tapes for an infant or a baby is not seen in a marketplace.SOLUTION: An auxiliary tool 1 to be used for a diaper 2 includes at least two hook parts 11 which have a hook surface H of a hook-and-loop fastener, and a connection part 12 which has elasticity and connects the hook part 11.SELECTED DRAWING: Figure 1【課題】2段の止着テープを使用し張力をクロスさせることによって、着用者が動きやすく、かつオムツがずれにくくなるのであるが、2段の止着テープを有するオムツは高額のために、2段の止着テープを有する子供用や赤ちゃん用のオムツは市場には見かけない。そこで、オムツとは別体であって、オムツの任意の箇所を引っ張ることができるオムツの補助具を提供することを目的とする。【解決手段】オムツ2に用いる補助具1は、面ファスナーのフック面Hを有する2以上のフック部11と、弾性を有しフック部11を連結する連結部12と、を備える。【選択図】図1
