In a sliding door closer comprising a biasing means for closing a door and a hydraulic shock absorber, one end of a communication hole that communicates each chamber partitioned by a piston of the hydraulic shock absorber with each other is opened in a side surface of a piston rod. Further, a ring valve is provided which opens and closes the opening of the communication hole by fitting into the piston rod and sliding in the axial direction, and the ring valve is configured to open the opening when the temperature is low.
Moreover, a sliding door closer is provided with a sliding means that slides according to the temperature so as to close the opening when the temperature is high.
