<p>A cuff (1A) for a blood pressure monitor includes a cuff main unit (10) wound around a measurement site of a living body, and a handle (50) provided on the outer peripheral surface of the cuff main unit (10) and gripped with a hand for fitting the cuff. The cuff main unit (50) includes a cover member (12) in which an air bag (20) for pressing the living body and a curled elastic member (22) wound annularly on the outside of the air bag (20) and radially changeable in size are contained, and a diameter increasing/decreasing mechanism for increasing/decreasing a diameter of the curled elastic member (22). The handle (50) has a push-button (51) for increasing/decreasing the diameter of the curled elastic member (22) by switching an operation of the diameter increasing/decreasing mechanism. This can provide a cuff for a blood pressure monitor permitting easy mounting/dismounting with respect to the measurement site of the living body.</p>
