PROBLEM TO BE SOLVED: To provide a blood pressure measuring device provided with such simple device constitution that the cuff can be easily wrapped around a measuring object part even by a user with disabled fingers.SOLUTION: To one end side 40a and the other end side 40b of a cuff body part 40, force is added in such a direction as to further contract the inner diameter of its cylindrical form. A rotary shaft 47 rotates clockwise to simultaneously move one end side 40a and the other end side 40b of the cuff body part 40. Consequently, the inner diameter of the cylindrical form of the cuff body part 40 can be contracted by pushing work using one hand only. The cuff body part 40 can thus be easily and quickly wrapped around the upper arm 100.COPYRIGHT: (C)2010,JPO&INPIT【課題】装置構成が簡単で、手先の不自由な方にとっても容易に被測定対象部位にカフの巻き付けを行なうことが可能な構成を備える血圧測定装置を提供する。【解決手段】カフ本体部40の一端側40aと他端側40bとには、筒状形態の内径をさらに縮径する方向に力が作用することで、回転軸47が時計回転方向に回転して、カフ本体部40の一端側40aと他端側40bとを同時に移動させる。その結果、片手を用いた押し付け作業のみにより、カフ本体部40の筒状形態の内径を縮径させることができ、容易にかつ素早くカフ本体部40を上腕100に巻きつけることが可能となる。【選択図】図3
