An over-the-top type cabinet door prop unit is characterized in that it comprises a fitting case to be rigidly fitted to the inner surface of one of the lateral walls of the cabinet, a movable spring holder vertically movable relative to the fitting case containing it and urged downward by compression springs, a link arm pivotably linked at the upper end to the movable spring holder by a pivot pin and a swing arm swingable around an arm spindle located in a lower portion of the fitting case and having a base section arranged around the arm spindle and linked to the lower end of said link arm by a link pin and an arm section extending from the base section and pivotably linked at the distal end thereof by an anchor pin to an anchor pin bearing secured to the over-the-top type cabinet door and that the pivot where the link arm and the base section of the swing arm is linked by the link pin is located closer to the cabinet door relative to the vertical axial line connecting the pivot pin and the arm spindle when the over-the-top type cabinet door is closed and moved onto the vertical axial line in the initial stages of the opening motion of the cabinet door and then further away from the cabinet door relative to the vertical axial line in the subsequent stages of the opening motion of the cabinet door until the cabinet door is placed on the top wall of the cabinet.

[ What is claimed is:] [1.] A cabinet having two lateral walls, a top wall, a bottom wall, a front wall, a rear wall, one of said walls comprising a hinged door, and a door prop unit comprising a fitting case fitted to an interior of said cabinet, a movable spring holder movable relative to the fitting case containing it and urged by compression springs, a link arm pivotably linked at an end thereof to the movable spring holder by means of a pivot pin, a swing arm swingable around an arm spindle located in a portion of the fitting case and having a base section pivotally mounted on the arm spindle, said base section of said swing arm linked to an opposite end of said link arm by means of a link pin at a location spaced radially outward from a rotational axis of said arm spindle, said swing arm having an arm section extending from the base section to a distal end thereof, an extension arm linked at its proximal end to the distal end of said swing arm by means of a joint pin, said swing arm and said extension arm being oblique relative to each other in said interior and coming in line with each other when said arm section and said extension arm are extended out of an opening of the cabinet, said extension arm and said swing arm being pivoted relative to each other and toward the opening of the cabinet when moved from an aligned to an oblique position, said extension arm pivotably linked at its distal end by means of an anchor pin to an anchor pin bearing secured to the cabinet door, wherein the link pin is located relative to an axial line connecting said pivot pin and said arm spindle so as to provide a desired force for assisting in closing and/or opening said door.
