Abstract
A cuff of a pulse wave meter equipped with an arteriosclerosis degree judgment device has air bags for compressing a living body having a double structure along an artery including an avascularization air bag and a pulse-wave measuring air bag. Provided at outer circumferential sides of these air bags are a curler for integrally pressing these air bags against an upper arm, and an air bag for pressing the curler from the outer circumferential side. A member for suppressing vibrations is provided between a curler-compressing air bag and the pulse-wave measuring air bag, and suppresses propagation of vibrations from the curler-compressing air bag to the pulse-wave measuring air bag. The pulse wave meter measures a pulse wave based on changes in internal pressure in the pulse-wave measuring air bag while the avascularization air bag provides avascularization at the peripheral side.
