< Topic >The cuffs for the hemadynamometer where measurement precision of blood pressure value improves, it offers.SolutionsAs for the cuffs for the hemadynamometer, the armor cover one side of the armor cover 110 in 110 which is wound around the arm of the subject and the longitudinal direction it is provided on edge side, the aspect because it locks in the part of the armor cover 110 where armor cover 110 winds in the arm of the subject and when being turned, other edge side of the armor cover 110 in the longitudinal direction the Interpolation the ring in external surface 110b of 160 which passes and armor cover 110, one side directing to edge side from other edge side of armor cover, 110 is provided in the band-like, winds the part of other edge side of the armor cover 110 which was looped ring 160 in radix point, in the arm of the subject and is turnedFastener the surface of 145 and Hook-and-Loop fastener 145 is covered, the coefficient of friction for ring 160, Hook-and-Loop fastener has with the grip section which is formed from the material where becomes larger than coefficient of friction with 145 and ring 160.< Choice figure >Drawing 4【課題】血圧値の測定精度が向上する血圧計用カフ、を提供する。【解決手段】血圧計用カフは、被験者の上腕に巻き付けられる外装カバー110と、長手方向における外装カバー110の一方端側に設けられ、外装カバー110が被験者の上腕に巻き回された時に、長手方向における外装カバー110の他方端側が挿通されるリング160と、外装カバー110の外表面110bに、外装カバー110の他方端側から一方端側に向けて帯状に設けられ、リング160を基点に折り返された外装カバー110の他方端側の部分を、被験者の上腕に巻き回された外装カバー110の部分に固定するための面ファスナ145と、面ファスナ145の表面を覆い、リング160に対する摩擦係数が、面ファスナ145とリング160との間の摩擦係数よりも大きくなる材料から形成されているグリップ部とを備える。【選択図】図4
