。[Claims for Utility Model Registration] 1. A piston linked to the opening and closing of the door and a compression spring that presses the piston are disposed in the cylinder chamber provided in the housing, and the cylinder chamber is divided into two by the piston. Among the compartments, one side that is the pressure side of the compression spring is the first oil chamber, and the other side is the second oil chamber. The oil chamber, a first conduit that communicates with the second oil chamber when the door is closed, and a second conduit that has a flow path opening/closing mechanism that is controlled so that the flow path can be shut off when the door is closed are provided in separate routes. Features a door closer. 2. The door closer according to claim 1, wherein the passage opening/closing mechanism of the second conduit passage comprises a solenoid valve and a check valve. 3. The door closer according to claim 1, wherein the passage opening/closing mechanism of the second conduit passage is constituted by a rotating body with a rotation stop lock.
