A door closer includes a closer casing (2), a pivot unit (3), and a length-variable damping cylinder (4). The pivot unit (3) includes a pivot axle (31), a cam member (32), and a cam follower member (33). The pivot axle (31) has a drive end portion (312) that extends into and that is retained rotatably in the closer casing (2), and a coupling end portion (311) that extends out of the closer casing (2). The cam member (32) is mounted co-rotatably on the drive end portion (312) of the pivot axle (31). The cam follower member (33) is disposed in the closer casing (2), and is acted upon by the cam member (32). The damping cylinder (4) is disposed in the closer casing (2), and has one end coupled to the cam follower member (33) and an opposite end anchored to the closer casing (2). <IMAGE> |
