PROBLEM TO BE SOLVED: To provide an electronic sphygmomanometer capable of easily performing the development operation of an arm cuff portion and the housing operation of the arm cuff portion in spite of a simple structure and capable of achieving miniaturization.SOLUTION: The electronic sphygmomanometer 1 has a case 20, a sphygmomanometer body 10 having a lid member 21 for closing the opening portion 20P of the case 20 in an openable manner and the arm cuff 2 for inserting the upper arm T of a measuring person to pressurize the upper arm T. The arm cuff 2 is folded to be housed in the housing spaces S1 and S2 formed by the case 20 and the lid member 21 while the opening portion 20P of the case 20 is closed by the lid member 21 and has an arm cuff shape restoring member 150 for restoring the shape of the folded arm cuff 2 to a state that the upper arm T can be inserted accompanied by operation for opening the lid member 21 to open the opening portion 20P of the case 20.COPYRIGHT: (C)2011,JPO&INPIT【課題】構造が簡単であるにもかかわらず、腕帯部の展開操作と腕帯部の収納操作が容易に行え、小型化を図ることができる電子血圧計を提供する。【解決手段】電子血圧計1は、ケース20と、ケース20の開口部20Pを開閉可能に閉鎖する蓋部材21とを有する血圧計本体10と、測定者の上腕Tを挿入して加圧するための腕帯部2とを有し、この腕帯部2は、蓋部材21によりケース20の開口部20Pを閉じた状態で、ケース20と蓋部材21とにより形成される収納空間S1、S2内に折り畳んで収納され、腕帯部2は、蓋部材21を開いてケース20の開口部20Pを開放する操作に伴い、折り畳まれた腕帯部2の形状を、上腕Tが挿入可能な状態に復帰させる腕帯部形状復帰用部材150を有する。【選択図】図2
