A return spring that is connected to the door and rotates when the door is opened and closed to linearly slide a piston that is housed in the cylinder section of the casing, and that is housed in the casing when the door is opened. A solenoid valve for opening and closing the hydraulic oil passage is installed in the cylinder part, and the solenoid valve opens and closes the pressure chamber formed between the piston and the solenoid valve to open and close the door as desired. In a door closer with a solenoid valve that is configured to stop the door at an opening angle position or release the stop of the door, the solenoid plunger operates a valve body of the solenoid valve, and the solenoid valve closes a hydraulic oil passage. A door closer with a solenoid valve that is biased in such a direction by a compression spring. 2. The plunger is provided with a set screw for pressing the valve body of the electromagnetic valve, and the set screw is screwed into the plunger body so that its protrusion length can be adjusted. Door closer with solenoid valve.
