A undermount-type sliding apparatus having an automatic closing device includes a movable rail provided under a receptacle and a fixed rail slidably coupled to the movable rail. A housing body is disposed on the fixed rail. A guide wall includes a curved guide portion, which has a curved shape and is spaced apart from one end of a housing space. A linear guide portion is connected to the curved guide portion. A rotary stopper is inserted into and guided by the guide wall while being caught by and released from the movable rail. An elastic member is disposed in the housing body, and is elastically coupled to the rotary stopper. In a closing operation, the rotary stopper catches the movable rail, and is thus automatically closed by elasticity. When positioned in the opening direction, the movable rail is released from the rotary stopper to enable an opening operation.

1. An undermount-type sliding apparatus, comprising: a movable rail provided under a receptacle;a fixed rail slidably coupled to the movable rail such that the movable rail is operable to be opened and closed; andan automatic closing device comprising: a housing body disposed on one side of the fixed rail, the housing body having a housing space having an open upper portion and a lower portion;a guide wall comprising: a curved guide portion partially protruding from one side to the other side in an open interior of the housing body, the curved guide portion extending from a lower end toward a central portion so as to have a curved shape and being spaced apart from one end of the housing space in an opening direction; anda linear guide portion connected to the curved guide portion, the linear guide portion extending in a closing direction to have a linear shape in a central portion of the housing space;a rotary stopper positioned so as to be inserted into and guided by the guide wall while being caught by and released from the movable rail; andan elastic member disposed in the housing body in the closing direction, the elastic member being elastically coupled to the rotary stopper;wherein, in a closing operation of the movable rail, the rotary stopper is operable to catch the elastic member so that the rotary stopper is automatically closed by elasticity of elastic force, and when the rotary stopper is positioned in the opening direction, the opening direction of the rotary stopper moves downward along the curved guide portion in a state in which the elastic member stays in a stretched state, so that the movable rail is released from the rotary stopper to enable an opening operation; andwherein the housing body has a through-hole, the linear guide is elastically deformable by an external force, and the through-hole is positioned in a way that, when a downward external force applies to the rotary stopper, the linear guide portion descends through the through-hole of the housing body by elastic deformation. 2. The undermount-type sliding apparatus of claim 1, wherein the rotary stopper comprises: a guide insert recess in an inner portion thereof, wherein the guide insert recess is inserted into the guide wall such that the guide insert recess is guided by the guide wall, the guide insert recess comprises:an opening contact surface;a curved contact surface above the guide wall inserted into the guide insert recess, wherein in an opened state, the opening contact surface is in contact with the linear guide portion, and the curved contact surface corresponds to the curved guide portion so as to come into contact with the curved guide portion; anda closing contact surface below the guide wall inserted into the guide insert recess, the closing contact surface coming into contact with the linear guide portion in a closed state;whereby, when closing the receptacle, the rotary stopper, which moves in the state in which the guide wall is inserted into the rotary stopper, can be released in response to rotation of the opening contact surface in contact with the linear guide portion and the curved contact surface in contact with the curved guide portion, so that the closing contact surface below moves in contact with a lower portion of the linear guide portion; andwhereby, when opening the receptacle, the rotary stopper can be caught in response to rotation of the opening contact surface in contact with the linear guide portion and the curved contact surface in contact with the curved guide portion. 3. The undermount-type sliding apparatus of claim 1, wherein the automatic closing device further comprises an elastic body disposed in the housing body in the closing direction, the elastic body has an elastic member insert space in a lower inner portion, the elastic body being positioned in the elastic member insert space, and an elastic member-fixing recess in one end of the elastic member insert space in the closing direction, the other end of the elastic member being fixed to the elastic member-fixing recess. 4. The undermount-type sliding apparatus of claim 1, wherein the rotary stopper further comprises an elastic member-fixing protrusion protruding from a lower portion of the rotary stopper in the closing direction, the elastic member-fixing protrusion having a protrusion-fixing recess in an inner portion thereof, a portion of the elastic member being fixedly inserted into the elastic member-fixing protrusion; and wherein one end of the elastic member is inserted into the protrusion-fixing recess such that the rotary stopper can be elastically coupled to the elastic member-fixing protrusion. 5. The undermount-type sliding apparatus of claim 1, wherein the rotary stopper has a catching recess in an upper portion thereof and an inclined surface in the opening direction, the inclined surface being inclined from an upper side portion of the rotary stopper to a side surface of the catching recess; and the undermount-type sliding apparatus further comprises a stopping lug disposed on the movable rail, the stopping lug protruding downward such that the stopping lug can be inserted into and caught by a stopper recess, wherein the inclined surface passes by an inclined position to minimize insertion interference when the stopping lug is caught by and coupled to the stopper recess, and the stopping lug is movable along with the movable rail so that the stopping lug is inserted into and released from the stopper recess. 6. The undermount-type sliding apparatus of claim 5, wherein, when the stopping lug comes into contact with the inclined surface, the external force that presses down the rotary stopper body occurs, and the linear guide portion of the guide wall descends due to the elastic deformation, and the stopping lug is coupled to the catching recess via catching.
