In the present embodiment, 51 is formed at the end of an inflow port 252 provided through the center of the lid 250,
On the other hand, the other end of the inflow port protrudes from the lid 250 to form a discharge pipe 253 to which the outlet pipe 6 communicating with the arm band 1 is connected. Further, a pair of first lid square holes 256 and second lid square holes 257 are formed in the lid 250. This is the first recess 40 of the valve opening / closing mechanism 401 described later.

6 and 7, the valve opening / closing mechanism 401 is formed of an elastic material such as rubber, and has a first concave portion 403 and a second concave portion 404 fitted with the lid 250 at both ends thereof.
After guiding the first concave portion 403 and the second concave portion 404, the first pin 405 and the second pin 4 projecting to the outside from the first lid square hole 256 and the second square hole 257, respectively.

When the drive unit 310 is de-energized, a force that does not block the inflow end 251 is given by the elastic force of the elastic material. It is necessary that the magnitude of this force is such that the valve member 402 does not block the inflow end 251 irrespective of the posture of the flow control device 200. By adopting this configuration, during blood pressure measurement,
If the power is turned off due to a failure or the like, the air in the arm band 1 is released, and the load on the human body can be quickly removed. On the other hand, in a general application of the flow rate adjusting device 200, a configuration may be adopted in which a force that closes the inlet 251 is applied by the elastic force when the drive device 310 is de-energized. That is, the valve opening / closing mechanism 4
Reference numeral 01 functions as an urging member for supporting the valve member 402 while applying a force in the opening or closing direction.

It was possible to prevent the accuracy of the speed control from deteriorating. That is, in the present embodiment, the valve opening / closing mechanism 401 is fixed to the lid 250. Therefore, when a desired current is supplied to the driving device 310 and the driving device 310 presses the valve member 402 with a desired force in the opposite direction to the force urged by the valve opening / closing mechanism 401, The vibration and the shake of the driving device 310 are less likely to be transmitted to the valve member 402 because they are merely in contact with each other via the valve member pressing portion 315 described later.

For this reason, the cost of the magnet can be reduced, and at the same time, a magnet having a stronger magnetic force can be used. As a result, the drive device itself can be reduced in size and power consumption, and further, along with the size reduction of the flow control device due to the square shape of the drive device, the size and the power consumption can be significantly reduced without reducing the flow control ability. Electricity could be realized.
