Abstract: There is provided a hydraulic damper installed to furniture, such as a sink or wardrobe, for buffering a door. In a buffer for absorbing shock created when a furniture door is closed, the buffer including a cylinder 10 having a cylinder chamber, and a piston 30 inserted in the cylinder chamber, supported by a rod 70 penetrating a packing 60 and a sealing housing 65, and urged by a first resilient spring 40 built in the housing, the buffer includes a pressing bracket 50, mounted to an end of the rod 70, for moving oil in the piston; an oil flow blocking housing 45 mounted to a boss 52 forming an end of the pressing bracket 50 and connected to the first resilient spring 40; and a second resilient spring 55, interposed between the oil flow blocking housing 45 and the pressing bracket 50, for providing the oil flow blocking housing 45 with a return force. Since the hydraulic damper with dual oil passages formed is installed at the closing/opening route of the furniture door, it can minimize a noise generated when the door is closed, regardless of specifications or weight of the door, thereby providing a silent indoor circumstance, regardless of specifications or weight of the door. Further, the door can be smoothly opened or closed, thereby prolonging a life of the hydraulic damper.
