To provide a door closer capable of easily securing necessary closing force.SOLUTION: The door closer includes: a first spring 17 that deforms elastically when the door opens and restores to generate a closing force when the door closes; a second spring 18 that is placed separately from the first spring 17, and deforms elastically when the door opens and restores to generate a closing force when the door closes; and a third spring 19 that is placed separate from the first spring 17 and the second spring 18 and deforms elastically when the door opens, and restores when the door closes to generate a closing force. When the door opens, cams 13a and 13b elastically deform the first spring 17, and a piston 12 elastically deforms the second spring 18 and the third spring 19.SELECTED DRAWING: Figure 1
【課題】必要な閉じ力を容易に確保することができるドアクローザを提供する。【解決手段】扉が開くときに弾性変形し、扉が閉じるときに復元して閉じ力を発生する第一バネ１７と、第一バネ１７とは別に設けられ、扉が開くときに弾性変形し、扉が閉じるときに復元して閉じ力を発生させる第二バネ１８と、第一バネ１７及び第二バネ１８とは別に設けられ、扉が開くときに弾性変形し、扉が閉じるときに復元して閉じ力を発生させる第三バネ１９と、を備え、扉が開くときに、カム１３ａ，１３ｂが第一バネ１７を弾性変形させ、ピストン１２が第二バネ１８と第三バネ１９を弾性変形させる。【選択図】図１
