CROSS REFERENCE TO RELATED APPLICATIONS AND CLAIM OF PRIORITY 
     This patent application claims benefit under 35 U.S.C. 119(e), 120, 121, or 365(c), and is a National Stage entry from International Application No. PCT/KR2013/008978, filed Oct. 8, 2013, which claims priority to Korean Patent Application No. 10-2012-0118311, filed July Oct. 24, 2012, the entire contents of which are incorporated herein by reference. 
     TECHNICAL FIELD 
     The present invention relates to a slide attachment and detachment device for a drawer that can connect the drawer to a slide intended for guiding pushing or pulling of the drawer or that can separate the drawer from the slide. 
     BACKGROUND ART 
     Generally, a receiving means for furniture such as a wardrobe, a cabinet or the like, and electrical appliances such as a refrigerator or the like includes: a drawer in which a storage product can be received; and a receiving body in which the drawer is received, wherein a slide intended for guiding pulling and pushing of the drawer is installed between the drawer and the receiving body so that the drawer can easily open and close. 
     There may be generated a case where a portion of the drawer is damaged during use of the drawer, and thus components should be replaced, or a case where the drawer should be completely separated from the slide in order to easily arrange products received in the drawer or to clean an inner portion of the drawer. 
     Meanwhile, when the drawer is large in size, or a storage product received in the drawer is heavy in weight, a load applied to the drawer is increased. In such a case, an undermount slide supporting the load of the drawer from a lower side may be applied. 
     Due to the reason described above, various types of slide attachment and detachment devices for a drawer intended for connecting the drawer to which the undermount slide is applied to the slide, or separating the drawer from the slide have been researched and developed. As a part thereof, the inventors of the present application have also suggested a relevant technology through Korean Utility Model No. 20-0396803 (Reg. Date: Sep. 20, 2005, Title of the device: Apparatus for adjusting horizontal tilting in drawer). 
     The slide attachment and detachment devices for a drawer, which have been suggested up to date, use a latch connection structure in which an elastic body is used in the slide attachment and detachment device so that the slide can be easily attached to or detached from the drawer. At this time, in order for the slide to be easily attached to or detached from the drawer, an elastic force of the elastic body should be weak. However, in a case where the elastic body having a weak elastic force is used, when the drawer is pulled at a rapid speed, the drawer pulled by a pulling limitation of the slide, and storage products cause a large impact force on a connecting part of the slide attachment and detachment device due to an inertia force thereof. Due to this, a connection of the slide and the slide attachment and detachment device may be released. 
     Also, since a plurality of components, including a metal elastic body, is mainly used, an assembly step should be necessarily included in a process for manufacturing the components, so a cost resulting therefrom may be generated. Furthermore, in the slide attachment and detachment devices for a drawer including the metal elastic body, when the drawer is installed in an environment with high humidity and is used for a long time, corrosion is generated from the metal elastic body so that storage products can be contaminated, and elasticity can be reduced. When foreign substances are inserted into a moving portion, the foreign substances can be mixed with the storage products, or the drawer cannot be smoothly attached to or detached from the slide. 
     SUMMARY 
     An object of an exemplary embodiment of the present invention is to provide a slide attachment and detachment device for a drawer capable of saving production time and cost consumed for manufacturing the slide attachment and detachment device for the drawer. 
     Also, another object of the exemplary embodiment of the present invention is to provide a slide attachment and detachment device for a drawer that can be used in environments having high humidity. 
     Also, a further object of the exemplary embodiment of the present invention is to a slide attachment and detachment device for a drawer in which an elastic support part supports a pulling shock of the drawer and enables an attachment and detachment function to be smoothly performed. 
     According to an aspect of the present invention, a slide attachment and detachment device for a drawer, which connects the drawer to a slide intended for supporting the drawer and a bottom part of the drawer and for guiding pulling or pushing of the drawer, or which separates the drawer from the slide, may include: a connecting part fixedly connected to at least one selected from a front part and a bottom part of the drawer; a fixation support part formed to protrude from the connecting part in a direction parallel to a pulling or pushing direction of the drawer, and having an operation hole formed to pass through a direction parallel to a direction toward one side of the slide in its central portion when the slide is positioned to support the drawer; an elastic support part formed to protrude from one edge of the operation hole and to cover the operation hole; and a level part formed to extend from an end of the elastic support part, one end of which has a coupling protrusion formed to protrude toward the slide by passing through the operation hole, and the other end of which protrudes in a direction opposite to the coupling protrusion, wherein when an external force parallel to the bottom part of the drawer and toward the slide is applied to the lever part, the elastic support part is elastically changed, so the coupling protrusion is pulled back into the operation hole, and when the external force applied to the lever part is released, the elastic support part is elastically returned, so the coupling protrusion protrudes to an outer portion of the operation hole. 
     Here, a portion of the elastic support part connected to the fixation support part may be positioned in the pushing direction of the drawer within the operation hole. 
     Also, a connecting neck having a minimum cross-sectional area may be formed in the elastic support part. 
     As described above, the slide attachment and detachment device for the drawer further include: an inclination control member connecting groove parallel to the operation hole and having one side opened toward the slide, and formed in the coupling part; an inclination control member slidably movably connected to the inclination control member connecting groove; and a wedge protrusion protruding toward an opening portion of the inclination control member connecting groove, and formed in the inclination control member, wherein the wedge protrusion is interposed between a bottom surface of the drawer and the slide when the slide is positioned to support the drawer, and the inclination control member is slidably moved in a direction toward the slide, so a distance between the bottom surface of the drawer and the slide is extended. 
     Also, the slide attachment and detachment device for the drawer may further include a shock absorbing part formed to protrude from the coupling part and disposed between the end of the slide and the front part of the drawer when the slide is positioned to support the drawer. 
     Also, as described above, with regard to the slide attachment and detachment device for the drawer, the connecting part, the fixation support part, the elastic support part, and the lever part may be made of a synthetic resin. 
     According to an exemplary embodiment of the present invention, a slide attachment and detachment device for a drawer is formed as one member so that time and costs consumed for manufacturing the slide attachment and detachment device for the drawer can be saved, and a moving portion into which foreign substances may be inserted is not formed so that hygienic properties can be improved. 
     Also, according to the exemplary embodiment of the present invention, a metal elastic body is not included in the slide attachment and detachment device for the drawer, thereby enabling use in environments with high humidity. 
     Also, according to the exemplary embodiment of the present invention, an elastic support part of the slide attachment and detachment device for the drawer disperses a pulling shock of the drawer as compressive stress so that a connection of the drawer and the slide can be prevented from being unintentionally released, and an attachment and detachment function can be easily performed.

     DETAILED DESCRIPTION 
     Exemplary embodiments of the present invention are capable of various modifications and alternative forms, embodiments of the present invention are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that there is no intent to limit example embodiments of the invention to the particular forms disclosed, but on the contrary, example embodiments of the invention are to cover all modifications, equivalents, and alternatives falling within the scope of the invention. In the following description, it is to be noted that, when the functions of conventional elements and the detailed description of elements related with the present invention may make the gist of the present invention unclear, a detailed description of those elements will be omitted. 
     Hereinafter, an exemplary embodiment of the present invention will be descried in detail with reference to the accompanying drawings. 
       FIG. 1  illustrates an appearance in which a slide attachment and detachment device for a drawer according to one exemplary embodiment of the present invention is connected to the drawer. 
     Referring to  FIG. 1 , the slide attachment and detachment device for the drawer  1  according to the one exemplary embodiment is connected to the drawer  80 . The slide attachment and detachment device for the drawer  1  is fixedly connected to at least one selected from a bottom part  81  and a front part  82  so that a slide  90  supporting the drawer  80  can be connected to or separated from the drawer  80 . 
     For reference, as previously described, the slide  80  supports the bottom part  81  of the drawer. The slide  80  may include: a fixing rail  91  fixedly connected to a receiving body (not drawn) in which the drawer  80  is received; a moving rail  93  moved along with the drawer  80  upon pulling or pushing the drawer  80  and intended for supporting the bottom part  81  of the drawer  80 ; and a middle rail  92  slidably movably connected to the fixing rail  91  and the moving rail  93  so that the moving rail  93  can be slidably movable in a pulling direction A or a pushing direction B with respect to the fixing rail  91 . 
     Here, the middle rail  92  is added for extending a pulled distance of the drawer  80 , namely, an operating distance of the slide  90 , and according to the need, the moving rail  93  may be directly slidably and movably connected to the fixing rail  91 . 
     That is, a slide in other types may be used as the slide  90  as needed. Since this fact is well known, the description of the slide  90  itself is omitted. 
     For reference, as illustrated, with regard to the slide attachment and detachment device for the drawer  1  according to the one exemplary embodiment, even though a pair of slide attachment and detachment devices for a drawer is generally installed in one drawer  90 , since the pair of slide attachment and detachment devices for the drawer  1  is only formed symmetrically and is identical to each other with respect to a structure and an operation thereof, the description of one slide attachment and detachment device for the drawer  1  may replace the description of another one. 
       FIG. 2  is a perspective view showing the slide attachment and detachment device for the drawer according to the one exemplary embodiment of the present invention, and  FIG. 3  is an exploded perspective view showing the slide attachment and detachment device for the drawer according to the one exemplary embodiment of the present invention. The slide attachment and detachment device for the drawer will be described with reference to  FIGS. 2 and 3 . 
     Referring to  FIGS. 2 and 3 , the slide attachment and detachment device for the drawer  1  according to the one exemplary embodiment of the present invention includes a main body  10  and an inclination control member  20 . 
     The main body  10  may include a connecting part  11 , a fixation support part  12 , a lever part  13 , an elastic support part  14 , and a shock absorbing part  15 . 
     The connecting part  11  is fixed to at least one selected from the bottom part (reference numeral  81  of  FIG. 1 ) and the front part (reference numeral  82  of  FIG. 1 ) of the drawer (reference numeral  80  of  FIG. 1 ). As illustrated, the connecting part may be formed to be simultaneously adhered to the bottom part  81  and the front part  82 , and a bottom connecting hole  111  and a front connecting hole  113  may be formed in the connecting part  11 . 
     A coupling member, such as a screw not illustrated, is inserted into the bottom connecting hole  111  and the front connecting hole  113  to be connected to at least one selected from the bottom part  81  and the front part  82  so that the connecting part  11  can be fixedly connected to at least one selected from the bottom part  81  and the front part  82 . 
     The fixation support part  12  is formed to protrude from the connecting part  11 . The fixation support part  12  is shaped to protrude in a direction parallel to a pulling direction (A of  FIG. 1 ) and a pushing direction (B of  FIG. 1 ) of the drawer  80 . 
     An operating hole  121  is formed in a middle portion of the fixation support part  12 . As illustrated in  FIG. 1 , when the moving rail  93  of the slide (reference numeral  90  of  FIG. 1 ) is positioned to support the bottom part  81  of the drawer  80 , the operating hole  121  may be formed in the fixation support part  12  in a direction parallel to a direction toward one side of the moving rail and an opposite direction of the direction. That is, the operating hole  121  may be formed on a virtual plane parallel to the bottom part  81  in a direction vertical to the moving rail  93 . 
     For reference, the terms ‘parallel to’ and ‘vertical’ mean ‘parallel to’ and ‘vertical’ in consideration of a processing error and the like rather than ‘parallel to’ and ‘vertical’ in terms of mathematics. 
     The elastic support part  14  may be formed to protrude from one edge of the operating hole  121  and may be shaped to cover the operating hole  121 . The shape of the elastic support part  14  will be described with reference to  FIGS. 4 and 5 . 
       FIG. 4  is a side view illustrating the shape of the elastic support part as viewed from direction IV indicated in  FIG. 2 , and  FIG. 5  illustrates a cross-sectional view taken along straight line V-V indicated in  FIG. 4 . 
     Referring to  FIGS. 4 and 5 , the elastic support part  14  is formed to protrude from one edge of the operating hole  121  of the fixation support part  12  and is formed to cover the operating hole  121 , and a remaining portion except for a portion connected to the fixation support part  12  is separated from the other edge of the operating hole  121 . 
     Here, as illustrated, the portion of the elastic support part  14  connected to the fixation support part  12  may be positioned in the operating hole  121  in the pushing (B) direction of the drawer. 
     Referring to  FIGS. 2 and 3  again, the lever part  13  is protrudly formed at the end of the elastic support part  14 , namely, at the best protruding portion from the fixation support part  12  in a portion which is not connected to the fixation support part  12 . 
     As illustrated, based on the fixation support part  12 , the lever part  13  protrudes in a direction opposite to a portion in which the moving rail  93  is disposed. At this time, the lever part  13  protrudes to a space between a direction parallel to the fixation support part  12  and a direction parallel to the operating hole  121 . The fixation support part  12  and the lever part  13  may form a fixed angle. Such an angle may be designed so that a user can easily grasp the lever part  13 . 
     A coupling protrusion  131  protruding in a direction toward the moving rail  93  by passing through the operating hole  121  may be formed in one end of both ends of the lever part  13 , the one end being disposed on a side at which the operating hole  121  is positioned. A guide surface  132  may be formed on the coupling protrusion  131 . As illustrated, the guide surface  132  may be shaped to be inclined in a direction far away from the moving rail  93  as the guide surface becomes close from the end of the coupling protrusion  131  to the pushing (B) direction of the drawer  80  gradually. 
     Accordingly, the coupling protrusion  131  protrudes roughly in a direction opposite to an extending direction of the lever part  13 . Each operation of the lever part  13 , the coupling protrusion  131  and the elastic support part  14  will be described later again. 
     The shock absorbing part  15  is formed to protrude from the connecting part  11 . As illustrated in  FIG. 1 , when the moving rail  93  of the slide  90  is positioned to support the drawer  80 , the shock absorbing part  15  is formed to be interposed between an end of the moving rail  93  and the front part front  82 . 
     A shock absorbing piece  151  is protrudly formed in the shock absorbing part  15 . The shock absorbing piece  151  is formed so as to absorb a shock generated from between the front part  82  of the drawer  80  and the end of the moving rail  93 . The operation of the shock absorbing part  15  will be described later again. 
     Meanwhile, an inclination control member connecting groove  115  to which the inclination control member  20  is slidably movably connected is formed in the connecting part  11 . The inclination control member connecting groove  115  is formed in a direction parallel to the operating hole  121  as illustrated, a wedge protrusion projecting groove  117  opened in a direction at which the moving rail  93  is disposed is formed to extend on one side of the inclination control member connecting groove  115 . 
     A wedge protrusion  211 , a knob  213 , a guide protrusion  215 , and a supporting protrusion  217  are formed in the inclination control member  20 . 
     The wedge protrusion  211  is formed to protrude in a direction toward the wedge protrusion projecting groove  117  when the inclination control member  20  is connected to the inclination control member connecting groove  115 . A portion of the wedge protrusion in which the wedge protrusion projecting groove  117  is in contact with the bottom part  81  may be formed to have a plan shape, and the remaining portion except for the portion may have inclined surface-like shape so that a thickness of the wedge protrusion  211  can be gradually reduced toward a protruding direction of the wedge protrusion  211 . 
     The guide protrusion  215  may be formed in a direction parallel to a direction in which the inclination control member  20  connected to the inclination control member connecting groove  115  is slidably moved. The guide protrusion  215  may enable the inclination control member  20  connected to the inclination control member connecting groove  115  to be smoothly slidably moved along the inclination control member connecting groove  115 . 
     That is, a guide groove (not drawn) having a shape corresponding to the guide protrusion  215  is formed in the inclination control member connecting groove  115 . The guide protrusion  215  is inserted into and supported by the guide groove (not drawn) so that sliding movement according to the inclination control member connecting groove  115  of the inclination control member  20  can be guided. 
     The knob  213  is a portion intended for enabling the inclination control member  20  to be slidably moved along the inclination control member connecting groove  115 . The knob  213  may be shaped to protrude in a fixed height from the bottom part  81  to a lower side of the drawer  80 , and at least one groove, protrusion, or the like may be formed at an end of the knob  213  so that a user can easily apply a force to the know with his or her finger. 
     Accordingly, as the user applies the force to the knob  213 , when the inclination control member  20  is slidably moved to the direction at which the moving rail  93  is disposed, namely, the inclination control member is slidably moved toward the protruding direction of the wedge protrusion  211 , the wedge protrusion  211  protrudes to the outside via the wedge protrusion projecting groove  117 . Also, when the inclination control member  20  is slidably moved in an opposite direction thereof, the wedge protrusion  211  may be pulled back into the wedge protrusion projecting groove  117 . 
     The supporting protrusion  217  functions to support the inclination control member  20  so that the inclination control member  20  cannot be separated from the inclination control member connecting groove  115 . That is, the supporting protrusion  217  prevents the inclination control member  20  from being separated from the main body  10  during a process for connecting the slide attachment and detachment device for the drawer  1  to the drawer  80 . 
     To do so, the supporting protrusion  217  is formed to further protrude to both sides than a width formed between both sides of the inclination control member connecting groove  115  so that the inclination control member  20  can be supported by the supporting protrusion  217 , as well as the guide protrusion  215  after the inclination control member  20  has been connected to the inclination control member connecting groove  115 . As a result, the inclination control member  20  can be prevented from being separated from the main body  10 . 
     Each operation of the lever part  13 , the coupling protrusion  131 , and the elastic support part  14  will be described with reference to  FIG. 5  again. 
     Referring to  FIG. 5 , a modified appearance of the elastic support part  14  resulting from applying an external force F to the lever part is indicated by a dotted line. That is, as illustrated, when the external force F is applied to the lever part  13  in a direction parallel to the bottom part  81  of the drawer, and toward the moving rail  93  of the slide from the fixation support part  12 , the external force F is transmitted to the elastic support part  14  via the lever part so that the elastic support part  14  can be elastically modified. 
     At this time, in order for the elastic support part  14  to be elastically modified as indicated by the dotted line, the elastic support part  14  may have smaller flexural rigidity than that of the lever part  13 . 
     Also, in order to minimize a change in a position of the lever part  13  generated when the coupling protrusion  131  is pulled back into the operating hole (reference numeral  121  of  FIG. 2 ) according to the elastic modification of the elastic support part  14 , the elastic modification of the elastic support part  14  may be mainly generated from a portion connected to the fixation support part  12 . To do so, as illustrated, a connecting neck  141  may be formed in the elastic support part  14 . 
     As previously described, the connecting neck  141  is a portion from which the largest elastic modification is generated when the external force F is applied to the lever part  13 . The connecting neck  141  may be formed to have a small cross-sectional area compared to different portions of the elastic support part  14 . In such a case, when the external force F is applied to the lever part  13 , the connecting neck  141  is elastically modified based on a portion C of the connecting neck  141  having a minimum cross-sectional area so that a position of the lever part  13  and a position of the elastic support part  14  can be changed in a shape resulting from being rotated with respect to the fixation support part  12 . 
     For reference, Tm corresponding to a sign, which is not described, represents a width of the portion C of the connecting neck  141  having the minimum cross-sectional area. For manufacturing convenience of the elastic support part  14 , a portion C having a minimum cross-sectional area may be formed in the connecting neck  141  in such a manner that a thickness of the elastic support part  14  is regularly formed, and a minimum width Tm is formed in the connecting neck  141 . 
     Meanwhile, when the external force F applied to the lever part  13  is released, the connecting neck  141 , which has been elastically modified, is elastically returned to a position before the external force F is applied. Accordingly, the positions of the remaining portions of the lever part  13  and the elastic support part  14  are also returned, so that the coupling protrusion  131  protrudes to the outside of the operating hole  121 . 
     As previously described, the main body of the slide attachment and detachment device for the drawer  1  according to the one exemplary embodiment is formed in integral form. At this time, in order for the connecting neck  141  of the elastic support part  14  to be elastically modified by the external force F or to be returned to its original position according to release of the external force and to have enough strength to prevent from being damaged during using it, the main body should be made of a material having high strength and sufficient elasticity. 
     Examples of the material having these properties include, but not is limited to, synthetic resin having high strength, fatigue resistance, hardness, wear resistance, and the like, such as polyoxymethylene, poly acetal and ABS resin, nylon, and the like. 
     When the process for applying the external force F to the lever part  13  or for releasing the external force from the lever part is repeated, tensile stress and compressive stress are repeatedly applied to the connecting neck  141  of the elastic support part  14 . When the tensile stress and the compressive stress is intensively applied to a specific portion of the connecting neck  141 , a lifespan of the connecting neck  141  may be reduced. 
     In order to prevent this, the connecting neck  141  may be shaped such that the tensile stress and the compressive stress are dispersively operated. That is, an outline of the elastic support part  14  including the connecting neck  141  may have a flexible curved shape in which a vertex is not formed between a portion of the elastic support part connected to the fixation support part  12  and a portion of the elastic support part connected to the lever part  13 . 
     An operation of the slide attachment and detachment device for the drawer  1  according to the one exemplary embodiment of the present invention having the structure as described above will be hereinafter described with reference to  FIGS. 6 to 8 . 
       FIGS. 6 and 7  illustrate perspective views for explaining the operation of the slide attachment and detachment device for the drawer  1  according to the one exemplary embodiment of the present invention. The operation will be described with reference to  FIG. 1 , as well as these drawings. 
     Referring to  FIGS. 6 and 7 , the main body  10  of the slide attachment and detachment device for a drawer  1  according to the one exemplary embodiment of the present invention, and the moving rail  93  are illustrated. For convenience, in  FIGS. 6 and 7 , the drawer  80  is not illustrated. 
     The moving rail  93  includes a moving rail body  931 . As illustrated, a coupling hole  932  is formed in the moving rail body  931 . The coupling hole  932  may be formed at a position corresponding to the coupling protrusion  131 . 
     In order for the moving rail  93  to support the bottom part  81  of the drawer  80 , one side of the moving rail  93  is coupled to the main body  10  by moving the moving rail from a position in the state illustrated in  FIG. 6  to a position in the state illustrated in  FIG. 7 . 
     In such a process, when the end of the moving rail body  931  is moved toward the shock absorbing part  15 , the coupling protrusion  131  in a state of further protruding than the fixation support part  12  is in contact with the moving rail body  931 . 
     At this time, as the end of the moving rail body  931  is moved toward the shock absorbing part  15  by a shape of the guide surface  132 , a force toward an inner direction of the operating hole (reference numeral  121  of  FIG. 2 ) is applied to the coupling protrusion  131 . Due to this force, the connecting neck  141  is elastically modified, the coupling protrusion  131  is pulled back into the operating hole  121 . 
     Then, the moving rail body  931  is further moved toward the shock absorbing part  15 , so when the coupling hole  932  is positioned at the coupling protrusion  131 , the force applied to the coupling protrusion  131  is released. Thus, while the connecting neck  141  is elastically returned, the coupling protrusion  131  protrudes to the outside of the operating hole  121  again. Accordingly, the coupling protrusion  131  is inserted into the coupling hole  932 , and accordingly, the main body  10  is coupled to the moving rail body  931 . 
     As such, after the main body  10  and the moving rail body  931  have been coupled to each other, when the user applies a force A to the drawer  80  in a pulling direction of the drawer, an edge of the coupling hole  932  is supported by an opposite portion of a portion in which the guide surface  132  of the coupling protrusion  131  is formed so that the coupling protrusion  131  can be maintained in a state of being coupled to the coupling hole  932 . When the user applies a force to the drawer in a pushing direction B of the drawer, an end of the moving rail body  931  is pressurized by the front part  82  of the drawer  80  so that the coupling protrusion  131  can be maintained in a state of being coupled to the coupling hole  932 . 
     Accordingly, when the drawer  80  is pulled (A) or pushed (B) after the coupling protrusion  131  has been coupled to the coupling hole  932 , the main body  10  and the moving rail  93  are maintained in a state of being coupled so that pulling (A) and pushing (B) of the drawer  80  can be guided by the slide  90 . 
     At this time, the shock absorbing part  15  is interposed between the end of the moving rail  93  and the front part  82  of the drawer  80 . The end of the moving rail  93  and the front part  82  of the drawer are elastically supported by the shock absorbing piece (reference numeral  151  of  FIG. 2 ) in a spaced direction between the end of the moving rail and the front part. 
     This is intended to constantly bring an edge of the coupling hole  932  into contact with the coupling protrusion  131  when the coupling protrusion  131  is coupled to the coupling hole  932 . Thus, a stable coupling state of the coupling protrusion  131  and the coupling hole  932  is maintained so that noise resulting from movement of the coupling protrusion  131  in the coupling hole  932  can be prevented from being generated, or movement of the drawer  80  with respect to the moving rail  93  can be prevented from being generated. 
     Also, when the user stops his or her action in the middle of pulling (A) the drawer  80  at a rapid speed, or the user pushes (B) the drawer  80  strongly, the end of the moving rail  93  may collide with the front part  82  due to an inertia force generated by movement of the moving rail  93 . Thus, the shock absorbing piece  151  of the shock absorbing part  15  interposed between the end of the moving rail  93  and the front part  82  is compressed and modified so as to absorb an impulsive force. 
     As such, the shock absorbing part  15  may enable the slide attachment and detachment device for the drawer  1  and the moving rail  93  to be stably coupled, may prevent the occurrence of noise upon pulling (A) or pushing the drawer  80 , and may enable the extension of a lifespan by absorbing an impact applied to the drawer  80  and the moving rail  93 . 
     Meanwhile, as previously described, when the drawer  80  is separated from the slide  90 , the user takes a motion to pull (A) the drawer  80 , and thereafter, he or she grasps both sides of the drawer  80  with both hands and holds the lever part  13  with fingers to apply a force (see F of  FIG. 5 ) so that the coupling protrusion  131  can be pulled back into the operating hole  121 , and thus can be separated from the coupling hole  932 , thereby enabling the main body  10  to be separated from the slide  90 . 
     Furthermore, when the drawer  80  is connected to the slide  90 , the bottom part  81  of the drawer  80  is mounted on the moving rail  93 , and thereafter, the drawer  80  is moved in the pushing (B) direction so that the moving rail body  931  can be relatively moved with respect to the main body  10  as illustrated in  FIGS. 6 and 7 , and as a result, the coupling protrusion  131  can be coupled to the coupling hole  932 . 
     For reference, in order to prevent a pain or an inconvenient touch sensation from being generated from the lever part when the user applies a force to the lever part  13 , a finger-shaped groove may be formed in the lever part  13 . 
       FIG. 8  is a perspective view illustrated for describing an operation of an inclination control member of the slide attachment and detachment device for the drawer according to the one exemplary embodiment of the present invention. 
     Referring to  FIG. 8 , the inclination control member  20  is slidably moved in a direction toward the moving rail  93  so that the wedge protrusion  211  can protrude through the wedge protrusion projecting groove  117 . The operation of the inclination control member will be described with reference to  FIG. 1 , as well as  FIG. 8 . 
     A tolerance resulting from a processing error and the like may be generated between the drawer  80 , the slide  90 , and a receiving body (not drawn) during a process for connecting the drawer  80  to the receiving body (not drawn). 
     For example, with respect to a connection angle of the bottom part  81  and the front part  82  corresponding to constitutive elements of the drawer  80 , a position in which the fixing rail  91  is fixed to an inner side of the receiving body (not drawn), a relative portion between the fixing rail  91  and the moving rail  93 , and the like, a fine tolerance may be generated. 
     Accordingly, during a process for assembling the drawer  80  with the receiving body (not drawn), the front part  82  may form a slope in a specific direction due to the tolerance as described above. 
     In such a case, since the front part  82  causes interference with a front part of another drawer which is not illustrated, pulling (A) and pushing (B) may not be smoothly performed, or noise may be generated. Also, since an arrangement state of the front part  82  is not regular, the appearance of a receiving means (not drawn) may not be beautiful. 
     At this time, an angle and a balance of the front part  82  may be amended by adjusting a position of the inclination control member  20 . 
     That is, as the inclination control member  20  is slidably moved toward the slide  90 , the wedge protrusion  211  protrudes to the outside of the wedge protrusion projecting groove  117 . The protruding wedge protrusion  211  is interposed between the bottom part  81  of the drawer  89  and the moving rail  93 . Accordingly, a distance between the bottom part  81  and the moving rail  93  may be extended. Here, since a level of the extension of the distance between the bottom part  81  and the moving rail  93  is relative to a protruding level of the wedge protrusion  211 , the level of the extension of the distance described above may be adjusted by adjusting a sliding level of the inclination control member  20  performed toward the slide  90 . 
     Meanwhile, as described above, since the inclination control member  20  is slidably moved to an appropriate position, after an angle and a balance state of the front part  82  have been adjusted, such a state should be maintained. 
     Accordingly, even though it is not illustrated, a plurality of unevennesses is formed in any one of the guide protrusion  215  and the guide groove (not drawn) along a lengthwise direction, and unevennesses corresponding thereto are also formed in another one so that the inclination control member  20  can be fixed at a position set by the user, and thus can be prevented from being arbitrarily moved. Also, a plurality of supporting grooves (not drawn) having a shape corresponding to the supporting protrusion  217  may be formed in a direction parallel to a direction at which the inclination control member  20  is slidably moved along both sides of the inclination control member connecting groove  115 . 
     As described above, in the slide attachment and detachment device for the drawer  1  according to the one exemplary embodiment of the present invention, since the main body  10  may be formed as one member, namely, may be formed in an integral form, the time and costs consumed for manufacturing the slide attachment and detachment device for the drawer  1  can be saved. 
     Furthermore, as described above, since the main body  10  is formed in the integral form, a moving portion into which foreign substances may be inserted is not formed so that hygienic properties can be improved. Accordingly, the slide attachment and detachment device for the drawer  1  according to the one exemplary embodiment of the present invention can be stably used even in devices for which hygienic properties are required, such as a refrigerator and the like. 
     Also, since a separate metal elastic body and the like are not included, and there is no possibility that the main body  10  itself will corrode, the slide attachment and detachment device for the drawer can be used even in environments having high humidity. 
     Although the slide attachment and detachment device for the drawer according to the exemplary embodiment of the present invention has been described, an idea of the present invention should not be limited to the exemplary embodiment presented in the specification, and those skilled in the art who understand the idea of the present invention will appreciate that other exemplary embodiments by various additions, modifications, deletions and substitutions of the constitutive elements can be easily suggested, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
