The invention provides a retracting apparatus of a sliding rail in which a self locking state is not cancelled without intention, a structure and an adjustment are simple, and a cost is inexpensive. In the retracting apparatus of the sliding rail, a guiding member (13) is provided with two parallel arranged guiding grooves (13a, 13b) which are linear in a predetermined range of a drawing and retracting direction, and are bent at a predetermined amount toward an approximately vertical lower side in an end portion in a drawing direction, an engagement member is provided with sliding pins (12 d, 12e), and the sliding pins (12d, 12e) slide along the guiding grooves (13a, 13b) in accordance with movement in the drawing direction, and moves downward at a predetermined amount in an end portion in the drawing direction, whereby an engagement between the engagement member (12) and a driving member (11) is cancelled, the engagement member ( 12) is locked, the driving member (11) and the engagement member (12) are engaged with each other at an automatic retract position on the basis of the movement of the moving rail in the retracting direction, and the lock is cancelled.

The invention claimed is: 1. A retracting apparatus which is provided with a fixed body and a moving body supported to said fixed body so as to freely move from one end position to another end position, and is automatically retracted to said one end position or said another end position, in the case that said moving body moves toward said one end position or said another end position and reaches an automatic retract position a predetermined distance apart from said one end position or said another end position, comprising: a driving member mounted to a side of said moving body or a side of the fixed body; a sliding member engaged with said driving member and sliding; a guiding member guiding said sliding member; and an energizing member energizing said sliding member to said one side or another side, wherein said guiding member is provided with a guiding groove which guides said sliding member in a predetermined range of said moving body during a period that said moving body moves from said one end position to an automatic retract position or from said another end position to the automatic retract position, and said guiding groove having a large diameter portion formed in an end portion of said guiding groove in a direction of said one moving end position or a direction of the another end position such that a width is larger than a width of said guiding groove, said sliding member is provided with a sliding pin which is inserted through said guiding groove and slides along said guiding groove, the sliding pin of said sliding member slides along said guiding groove in accordance with movement of said moving body in said one end position direction or the another end position direction of the moving body, and rotates in said one end position direction or the another end position direction at said guiding groove end portion, whereby a dimension in an orthogonal direction to said guiding groove is changed, the sliding pin is fitted to said large diameter portion and locks said sliding member, an engagement between said sliding member and said driving member is cancelled, said driving member and said sliding member are engaged with each other at said automatic retract position on the basis of the movement of said moving body in said another end position direction or the one end position direction, and the lock of said sliding member is cancelled. 2. A retracting apparatus as claimed in claim 1, wherein the sliding pin of said sliding member is allowed to rotate in said one end position direction or the another end position direction in the end portion in the side of the one end position or the end portion in the side of the another end position of said guiding groove, and said sliding member is pressed by said driving member so as to rotate around said sliding pin in said one end position direction or the another end position direction by moving said moving body in said one end position direction or the another end position direction, in the case that said sliding member is in the end portion in the side of said one end position or the end portion in the side of the another end position of said guiding groove in a state in which the engagement of said sliding member with said driving member is cancelled, whereby the engagement between said sliding member and said driving member is recovered. 3. A drawer apparatus provided with a drawer portion which is freely drawn and retracted with respect to a cabinet main body, wherein the drawer apparatus is provided with the retracting apparatus as claimed in claim 2, the fixed body of said retracting apparatus is formed as the cabinet main body or is mounted to the side of the cabinet main body, said moving body is formed as the drawer portion or is mounted to the side of the drawer portion, and the guiding member is mounted to the side of said cabinet main body or the side of the drawer portion. 4. A sliding door apparatus comprising: a cabinet main body; and a sliding door supported to said cabinet main body so as to be freely drawn and retracted, wherein the sliding door apparatus is provided with the retracting apparatus as claimed in claim 2, the fixed body of said retracting apparatus is formed as the cabinet main body or is mounted to the side of said cabinet main body, and said moving body is formed as the sliding door or is mounted to the side of the sliding door. 5. A drawer apparatus provided with a drawer portion which is freely drawn and retracted with respect to a cabinet main body, wherein the drawer apparatus is provided with the retracting apparatus as claimed in claim 1, the fixed body of said retracting apparatus is formed as the cabinet main body or is mounted to the side of the cabinet main body, said moving body is formed as the drawer portion or is mounted to the side of the drawer portion, and the guiding member is mounted to the side of said cabinet main body or the side of the drawer portion. 6. A sliding door apparatus comprising: a cabinet main body; and a sliding door supported to said cabinet main body so as to be freely drawn and retracted, wherein the sliding door apparatus is provided with the retracting apparatus as claimed in claim 1, the fixed body of said retracting apparatus is formed as the cabinet main body or is mounted to the side of said cabinet main body, and said moving body is formed as the sliding door or is mounted to the side of the sliding door.
