PROBLEM TO BE SOLVED: To provide a door closer for closing a turnably supported door, mountable to various door mounting holes, simplified in structure and reducing an operator's burden when mounted, and to provide a bracket and a stationary plate used for the door closer. SOLUTION: The door closer has a body replacement seat plate mountable to multiple kinds of doors through a body mounting plate installed on the back face of a door closer body. The bracket has a threaded hole for the stationary plate to allow mounting to the stationary plate, and an H-shaped mounting hole and a central mounting hole which allow mounting to an upper frame. The stationary plate has an oblong hole counterposed to the threaded hole for the stationary plate, and a mounting hole and an L-shaped mounting hole counterposed to the H-shaped mounting hole. The stationary plate installed at the bracket is made movable along the oblong hole to vary the mounting hole position of the H-shaped mounting hole in the bracket. COPYRIGHT: (C)2009,JPO&INPIT
