。[Scope of Claim for Utility Model Registration] A support shaft that is fixedly provided on the floor side and supports the door, and a damper oil that is fixed to the support shaft and is filled in an internal damper chamber to control the opening and closing operation of the door. a cylinder that rotates together with the piston; a piston that is screwed onto the cylinder and has a check valve that moves up and down as the cylinder rotates;
A first speed governor rod for adjusting the door closing speed in the first door closing operation up to an arbitrary angle during the door closing operation, and a first speed governor rod for controlling the door closing speed in the second door closing operation from that angle to closing. A second regulating rod is provided concentrically, and a cylindrical body is fitted into a through hole of the piston and has first and second regulating passages above and below, and is open during the first door closing operation. A first regulating member regulates the amount of damper oil passing through the first regulating passage, and a second regulating member regulates the amount of damper oil passing through the second regulating passage, which is opened when the second door is closed. A vertical shaft type door closer characterized in that the door closing speed is changed by regulating it with a rod.
