  The slide bar 35 is a guide support portion that supports the drawer body 2 so as to guide the drawer / storage, and the drawer body 2 is pulled out (lower drawer body 2 in FIG. 2) and stored (upper stage in FIG. 2). In the drawer body 2) on the side, the bottom plate 23 can be supported in the entire area of the support surface 50 by maintaining the support surface 50 of the sliding bar 35 parallel to the bottom plate 23.

  The slide bar 35 is rotatable about the support shaft 51 as a center of rotation with respect to the support shaft 51 protruding from the side plate 30 so that the axis is along the direction orthogonal to the pull-out direction of the drawer body 2 in the horizontal direction. The front side is inclined downward in the housed state of the drawer body 2 and is in a horizontal state in the drawer state of the drawer body 2.

  Specifically, the slide bar 35 is pushed down on the rear side of the slide bar 35 with the support shaft 51 as a boundary by the bottom plate 23 of the drawer body 2 whose rear side is lowered by lifting the front plate 20. It rotates so that the rear side of the sliding bar 35 is lowered as a rotation center. In addition, since the entire area of the support surface 50 of the cross rail 35 becomes horizontal by this rotation, the entire area of the support surface 50 can be brought into contact with the bottom plate 23 of the drawer main body 2 in parallel. The drawer main body 2 in the released state can be supported so that the bottom plate 23 is horizontal. At this time, the drawer main body 2 can be pulled out in the horizontal direction by releasing the engagement of the engaged portion 4a with the restriction engaging portion 4b.

Has been.

  The long hole 60 is opened with the longitudinal direction as the direction along the vertical movement direction of the drawer body 2. The upper end 60a of the elongated hole 60 is in a position where it comes into contact with the restriction shaft 61 in a state in which the drawer body 2 is housed, and by contacting the restriction shaft 61, the inclined state of the rail 35 can be maintained. .

  The lower end 60b of the long hole 60 is in a position where it comes into contact with the restriction shaft 61 when the drawer body 2 is lifted and disengaged. By contacting the restriction shaft 61, the slide bar 35 is brought into a horizontal state. In addition to this, excessive rotation exceeding the horizontal state of the sliding bar 35 can be prevented.

  The sliding bar 35 may be horizontal when the drawer body 2 is stored and may be inclined when the drawer body 2 is pulled out.

  The drawer storage tool 1 described above can prevent the drawer main body 2 from popping out due to the vibration of the drawer main body 2 in the housed state by the engagement of the engaged portion 4a with the restricting engagement portion 4b in the lock device 4. Further, when the drawer main body 2 is pulled out, the front plate 20 is lifted to release the contact engagement of the engaged portion 4a from the rear with respect to the restricting engagement portion 4b, and the drawer main body 2 can be pulled out.

  In this locking device 4, the engaged portion 4 a is a front end of the bottom plate 20 of the drawer main body 2 that is a basic constituent member of the drawer storage device 1, and the restricting engagement portion 4 b is a basic component of the drawer storage device 1.
