PROBLEM TO BE SOLVED: To provide a self-holding type electromagnetic valve device which can suppress power consumption because it is unnecessary to continuously carry electricity to an electromagnetic coil while being a simple constitution which can reduce the size and weight of the device, and a cost. ! SOLUTION: There is arranged an elastic body (31) having elasticity at a valve seat part (30) for closing a discharge port (16) by making a valve body (20) seated. In a state that the valve body (20) is separated from the valve seat part (30), the discharge port (16) is closed by carrying electricity to an electromagnetic coil (27) so as to press the valve body (20) to the elastic body (31) by a load smaller than a load at which the elastic body (31) is elastically deformed, and on the other hand, in a state that the valve body (20) is seated on the valve seat part (30), the discharge port (16) is opened by carrying electricity to the electromagnetic coil (27) so as to press the valve body (20) to the elast |
