An electromagnetically driven valve (10) includes a valve-opening side moving element (21) and a valve-closing side moving element (31) having rotatably supported support portions (23, 33) and carrying out oscillating movement between a valve-opening position and a valve-closing position around the support portions (23, 33) respectively, and an electromagnet (40) having a coil (42) implemented by a monocoil and arranged between the valve-opening side moving element (21) and the valve-closing side moving element (31). The valve-opening side moving element (21) and the valve-closing side moving element (31) are held at a position intermediate between the valve-opening position and the valve-closing position while electromagnetic force is not applied. Magnetic permeability of a material forming the valve-opening side moving element (21) is different from that of a material forming the valve-closing side moving element (31). According to such a structure, an electromagnetically driven valve with a simplified structure, of which initial drive is facilitated, is provided. |
