Abstract: In a blood pressure monitor, when a main unit is mounted on a mounting surface such as a desk, a bulging region of a first tube and a bulging region of a second tube, both located at a rear surface of the main unit, come into contact with the mounting surface. This can avoid the main unit from sliding even when the main unit is pulled by the first and second tubes. Consequently, a blood pressure monitor has a configuration in which the main unit is less likely to slide over the mounting surface even when the main unit is pulled by tubes connected to the main unit.
