PROBLEM TO BE SOLVED: To provide a cuff for a sphygmomanometer, relaxing a pressure sense to a measured part from a ring-like member, and preventing a fold of the distal end side rather than the ring-like member.SOLUTION: This cuff 10 for the sphygmomanometer includes: a cuff body 50 formed in a belt shape an inflation bag 56 supported within the cuff body 50 the ring-like member 52 which is held on the cuff body 50 at a prescribed distance from the base end of the cuff body 50, and into which a distal end part of the cuff body 50 is inserted and an installation member 54 connecting the cuff body 50 on the base end side rather than a holding position of the ring-like member 52 and the ring-like member 52 side.COPYRIGHT: (C)2013,JPO&INPIT【課題】リング状部材から被測定部への圧迫感を緩和するとともに、リング状部材よりも先端側の折れ曲がりを防止することのできる血圧計用カフを提供する。【解決手段】本発明の血圧計用カフ10は、帯状に形成されたカフ本体50と、カフ本体50の内部に支持された膨張袋56と、カフ本体50の基端から所定の距離を持ってカフ本体50に保持されるとともにカフ本体50の先端部が差し込まれるリング状部材52と、リング状部材52の保持位置よりも基端側のカフ本体50とリング状部材52側とを連結する取付部材54を備える。【選択図】図4
