Abstract
A solenoid valve includes a solenoid portion that moves a pin to one axial side and a nozzle portion including a valve body connected to one axial side of the pin, and a nozzle body that houses the valve body. The nozzle body includes a valve chamber that has a cavity recessed toward one axial side with an opening on the other axial side and that houses the valve body on one axial side of the cavity, and a solenoid housing portion that houses the solenoid portion on the other axial side of the valve chamber of the cavity. The valve body is driven by the pin and moves to one axial side to close a valve hole and is urged by a spring and moves to the other axial side to open the valve hole.
