A cuff for sphygmomanometer comprises an air bag (34) for pressing against a living body, a sheathing cover (30) containing therein the air bag (34) and a fixing unit (40) provided on the sheathing cover (30). A portion near another end portion (30b) of the sheathing cover (30) is inserted between a roller (44) and a stopper (46), and fixed by pressing the roller (44) to the stopper (46). The roller (44) is only rotatable in a direction in which the size of the annular portion of the sheathing cover (30) reduces. By configuring in such a manner, a cuff for sphygmomanometer is provided which is easy to be sleeved on the upper arm, capable of repeating the operation of sleeving on the upper arm, and in addition thereto, simple in configuration and capable of being manufactured inexpensively.血壓計用壓脈帶具備用以壓迫生物體的空氣袋(34)、內部包含空氣袋(34)的外裝包覆(30)及設置於外裝包覆(30)的固定單元(40)。外裝包覆(30)之靠近另一端部(30b)的部分,係插穿被設置於固定單元(40)的輥(44)和止動器(46)之間,且藉由利用止動器(46)朝向輥(44)推壓而被固定。輥(44)僅可朝外裝包覆(30)之環狀部分的大小減少的方向轉動。藉此構成,可作成可易於進行對上臂的安裝,同時可穩定地重現對上臂的安裝,而且構成簡單並可廉價地製作之血壓計用壓脈帶。20D...壓脈帶30a...一端部30b...另一端部30...外裝包覆31...內側包覆32...外側包覆34...空氣袋35...套環38...拉手40...固定單元41...外殼41a、41b...開口部42...支持框44...輥44a...軸46...止動器46a...軸47...從動輥47a...軸
