ABSTRACT:
A pulse wave detecting apparatus having a pulse wave sensor for detecting pulse wave produced from an arterial vessel of a subject, the pulse wave sensor being movable along a cross line crossing the arterial vessel so as to be positioned in place relative to the arterial vessel, and pressed against a body surface of the subject so as to detect the pulse wave produced from the arterial vessel, a frame member for being set on the body surface of the subject, a guide device supported by the frame member, for guiding the pulse wave sensor within a predetermined length along the cross line, a feeding screw supported by the frame member such that the feeding screw is rotatable about a longitudinal axis thereof parallel to the cross line, the feeding screw being threadedly engaged with the pulse wave sensor, a drive motor supported by the frame member such that the drive motor is located adjacent to the body surface when the frame member is set on the body surface of the subject, and a transmission device provided between the drive motor and the feeding screw, for transmitting rotating force of the drive motor to the feeding screw, so as to move the pulse wave sensor along the cross line.
