The opening angle of the guide guide 5, the protrusion degree of the retaining protrusion 26, and the protrusion degree of the locking protrusion 28 are set so that the guide guide 5 cannot be locked, and the rear end part 7 (fitting part 25) of the wagon W is formed. When the wagon W is further pushed into the storage opening 1 while being supported by the support 9, the guide surface 6 is pushed inward until the guide surface 6 becomes substantially parallel to the slide rail 11. The locking projection 28 and the engagement recess 27 are configured to be pivoted horizontally so that the guide 5 is retracted into the storage opening 1 together with the wagon W, and the guide 5 is When retracted into the storage opening 1, the wagon W is pulled forward. Even if it moves, the latching convex portion 28 abuts against the stopper surface 26B of the retaining projection 26 and is retained so that the guiding guide 5 moves forward together with the wagon W (see FIGS. 4 to 8). .

  Further, when the stored wagon W is pulled forward from the storage opening 1, when the guide guide 5 reaches the front end of the slide rail 11, it automatically protrudes outward from the opening edge of the storage opening 1. When the guide guide 5 is opened to the maximum extent, the locking projection 28 can be disengaged from the engagement recess 27 and the wagon W can be further pulled out (separated from the cabinet C). ing.

  Further, the retaining protrusion 26 of the present embodiment is provided so as to be movable in the direction of the outer surface of the guide guide 5 (can be immersed in the guide surface 6) and is always protruded and urged by the elastic body 29. is doing.

  Specifically, the guide guide 5 is provided with a recess 30 that opens on the guide surface 6 side, and the retaining protrusion 26 is accommodated in the recess 30, and the retaining protrusion 26 is disposed on the tip side (the ride The leading end of the rising surface 26A is pivotally attached to the recess 30 (guide guide 5) by the support shaft 31, and is provided so as to be rotatable so that the proximal end side of the retaining projection 26 undulates with respect to the guide surface 6. ing.

  Further, when the retaining projection 26 is pivoted and retracted to the maximum extent in the recess 30, the retaining projection 26A is arranged so that the climbing surface 26A of the retaining projection 26 is substantially flush with the guide surface 6. The shape of 26 and the shape of the recess 30 are set and configured.

  The retaining protrusion 26 includes a torsion spring 29 as the elastic body 29. One end of the torsion spring 29 abuts against the retaining protrusion 26 and the other end contacts the bottom of the recess 30. Arranged so as to be in contact with each other, the urging force of the torsion spring 29 is configured so that the retaining projection 26 is always urged and projected from the guide surface 6.

  Further, the retaining projection 26 and the recess 30 are provided with a rotation limit stopper 34 that prevents the retaining projection 26 that is biased from projecting excessively in the projecting direction by abutting each other.

  The retracting structure of the retaining protrusion 26 is such that when the wagon W is stored in the storage opening 1, the locking protrusion 28 cannot be locked to the engaging recess 27 (the rear end of the wagon W). Even when the guide guide 5 has been retracted and moved backward in the storage opening 1 first, the locking projection 28 will eventually become the engagement recess. 27 is to be locked. That is, when the rear end 7 (locking convex portion 28) moves backward along the guide surface 6 retracted into the storage opening 1 and substantially parallel to the slide rail 11, it will hit the retaining projection 26. The retaining projection 26 is easy to ride on the riding surface 26A because the tip side adjacent to the guide surface 6 is a gentle riding surface 26A. At this time, the retaining projection 26 is attached to the elastic body 29. Since it is difficult to cause resistance by moving against the force, the engaging projection 28 is engaged with the engaging recess 27 (see FIG. 10).

  Further, in this embodiment, when the wagon W is pulled out from the storage opening 1, the lock mechanism 14 that can be locked / releasable to lock the wagon W with respect to the storage opening 1 in a non-detachable state is used for the slide. A rail 11 and the guide guide 5 are provided.

  Specifically, as shown in FIGS. 11 to 13, the locking mechanism 14 of the present embodiment is provided with a stopper switch 32 that can be pivoted up and down on the upper surface of the front end portion of the protruding portion 11 </ b> B of the slide rail 11. ing.

  Further, the stopper switch 32 is formed so that the rear side of the slide rail 11 is tapered at an acute angle, and the side surface of the acute angled tip portion located on the inner side of the storage opening 1 is blocked by an inclined surface 32A. In addition, the sharp-angled tip portion is provided so as to be able to turn up and down in a range of approximately 90 degrees from the state in which the sharp tip portion is laid down on the upper surface of the upper protruding portion 11B to the state in which it stands up.

  On the other hand, the other end portion of the guide guide 5 is formed in a shape projecting upward from the upper projecting portion 11B of the slide rail 11, and the upper end of the slide rail 11 is formed above the other end portion. An inclined abutting portion 33 having an inclination angle corresponding to the blocking inclined surface 32A of the stopper switch 32, which is depressed on the upper surface of the front end portion of the projecting portion 11B, is integrally projected, and the inclined abutting portion 33 is a stopper in the depressed state. By contacting the blocking inclined surface 32A of the switch 32, the sliding guide 5 is prevented from sliding forward, and the guiding guide 5 is prevented from opening outward (see FIG. 12).

  When the stopper switch 32 is activated and rotated upward, the inclined contact portion 33 cannot be brought into contact with the blocking inclined surface 32A. As a result, when the guiding guide 5 moves forward while opening outward, the inclined contact portion 33 is inclined. The abutting portion 33 avoids the stopper switch 32 and leads to the front of the storage opening 1 so that one end of the guide 5 protrudes (see FIG. 13).

  Therefore, by setting the stopper switch 32 in the down state, the wagon W can be locked so that it cannot be separated from the storage opening 1 (cabinet C). By switching the stopper switch 32 from the locked state to the standing state, the wagon W can be It is configured to be able to be unlocked and separated from the cabinet C.
