Cuff for blood pressure monitor, and blood pressure monitor having the same

A blood pressure monitor, comprising:

• a cuff for a blood pressure monitor including a fluid bag inflated and deflated as a fluid comes in and out;
• an inflating/deflating portion for inflating and deflating said fluid bag;
• a pressure detecting portion for detecting a pressure in said fluid bag;
• and
• a blood pressure value calculating portion for calculating a blood pressure value based on pressure information detected by said pressure detecting portion;
• wherein
• said fluid bag includes an inner wall portion located on an inner side-in the state where said cuff for a blood pressure monitor is wound around a living body, an outer wall portion located on an outer side than said inner wall portion, and a side wall portion connecting a side end portion of said inner wall portion and a side end portion of said outer wall portion and folded inwards in a width direction of said fluid bag in a deflated state where said fluid bag is not pressurized to thereby form a gusset at a side end portion of said fluid bag, and
• a joined portion for reducing expansion of the gusset formed by said side wall portion is provided at a region of the side end portion of said fluid bag in its winding direction around the living body.
