To provide a hemadynamometer having excellent wearability capable of preventing winding displacement.
Hemadynamometers 1A-1G are provided. A part of the living body where an artery exists is called a measurement part M. Each of the hemadynamometers comprises a pair of arms 2A and 2B having curved forms that fit along the measurement part M, a pressing means 4 arranged on the inner surface of the pair of arms 2A and 2B for applying a pressure to the measurement part M, and a detecting means 5 for detecting vibration information of the measurement part M via the pressing means 4. Base end sides of the pair of arms 2A and 2B are connected rotatably at rotating sections 2a and 2b so that the arms are openable and closable. The hemadynamometer is characterized by that the rotating sections 2a and 2b are provided with a reverse rotation preventing means 7 (11 and 12) that prevents rotation of the arms in the opening direction when the pair of arms 2A and 2B are rotated in the closing direction.
