クローザの速度調節装置。 A cylinder whose both ends are closed with cylinder caps and whose inside is filled with hydraulic oil is inserted into the cylinder so that it can move in the axial direction, is biased in one direction by a spring, and is moved in the axial direction of the cylinder. a piston that forms a rack along the axis of the cylinder; a pinion that is rotatably supported in the cylinder at an angle perpendicular to the cylinder axis, has at least one end protruding outside the cylinder, and is formed in a portion inside the cylinder; The pinion shaft is engaged with the rack of the piston, the high pressure space in front of the piston that becomes high pressure when the piston moves when the door is closed, and the low pressure space on the side that houses the spring that presses the piston is inserted into the oil guide hole that communicates with each other. An insertion hole is formed that passes through the front end of the piston in the cylinder axial direction, and a check valve is provided at the end of this communication hole on the high pressure space side, and the piston is connected to the piston through the high pressure space. A release pin is provided on the opposing high-pressure side cylinder cap so that the inner end partially interferes with the movement locus of the valve body of the check valve, and the position of this release pin in the cylinder axial direction can be adjusted. A closer speed adjustment device characterized by:
