A shock-absorbing damper for absorbing the impact force generated during the opening/closing of a furniture door, the damper including: a load pin in a housing to move back and forth during the opening/closing of the furniture door; a main valve coupled to the load pin to form a first flow path; a check valve coupled to a guide bar of the main valve in a manner to form a second flow path; a guider coupled to the main valve to guide the fluid flow; and a pressure adjuster interposed between the main valve and the check valve to vary the first flow path. The pressure adjuster and the guider are provided in the shock-absorbing damper to vary a flow path corresponding to an opening/closing load of the furniture door, thereby opening/closing the furniture door at a set speed regardless of the size or weight.
