A closing impact buffering device of a furniture door is provided to reduce noise generated when closing the door, and to extend life time of the furniture by passing oil in an oil chamber through an oil groove and absorbing the shock force resulting from the closed door. A closing impact buffering device of a furniture door comprises a cylinder(10), a piston(20), a spring(30), a valve(40), a projection, and a check valve(60). The cylinder has an oil chamber(11). The piston is reciprocated by a rod(23) passing through a sealing member(21) and a buffer member(22). The spring is mounted with a guide(31) at the front thereof. The valve has an oil passage(47) on the inner wall thereof. The projection on which a plurality of oil grooves is formed in the longitudinal direction is integrally formed on the front end of the valve. The oil of the oil chamber passes through an oil groove, an oil passage and a gap(41) of the valve to absorb the shock force resulting from the closed door. |
