The inner case 13 is provided in a shape including a lower flat surface portion 20 that forms a key receiving surface and an upper flat surface portion 22 that is continuous with the lower flat surface portion 20 via a stepped portion 21. As shown in FIG. 2, the lower plane part 20, the step part 21, and the upper plane part 22 are arranged in two upper and lower stages, so that the accommodation rows of the keys K are arranged in two upper and lower rows. Has been.

  A slot hole 25 is formed in a region straddling the lower plane part 20, the stepped part 21 and the upper plane part 22, and a part of the key holding tool 15 is exposed in the slot hole 25. ing. In addition, in the upper plane portion 22, a display portion 26 corresponding to each slot hole 25 is provided, and the display portion has an attribute of the key K, that is, which key is displayed as shown in FIG. And a transparent cover plate 28 positioned on the label L. Moreover, the partition part 30 which controls the entanglement etc. with the key with which the key K adjoins is formed in the lower plane part 20 for every predetermined space | interval.

  The key holding tool 15 is disposed on the back side of the upper flat surface portion 22 and is fixed via a pressing plate (not shown). As shown in FIGS. 3 to 8, the key holding tool 15 includes a base portion 33 located around the protruding portion 32 formed on the back surface side of the upper flat portion 22, and the base portion 33. And a pair of holding bodies 35, 35 provided with one end as a fixed end and the other end as a free end and arranged at a predetermined interval from each other, and a free end side relative portion of each holding body 35 And projecting portions 36 and 36 projecting toward the other holding body.

The base portion 33 is provided with a bottomed shape. Specifically, it is composed of a bottom surface portion 40 having a substantially oval shape in plan view and a peripheral surface portion 41 connected to the periphery of the bottom surface portion 40, and is provided in a shape that opens the opposite side of the bottom surface portion 40. . The holding bodies 35, 35 are continuously provided from one long side of the peripheral surface portion 41 so as to protrude in a direction substantially orthogonal to the long side, and the base end (upper end in FIG. 4) is a fixed end. On the other hand, the tip (lower end in the figure) is formed as a free end.

  The convex portion 36 is provided in a substantially conical shape so that the contour becomes narrower toward the distal end, and is provided in a shape including an inclined portion 42 that is positioned so that the distal end is closer to the fixed end side than the base portion. . More specifically, each convex portion 36 includes an upper inclined surface 42A and a lower inclined surface 42B that are positioned on the fixed end side toward the tip, and the inclination angle of the upper inclined surface 42A is larger than that of the lower inclined surface 42B. It is provided on a slightly gentle slope. Further, the upper inclined surface 42A is formed so that the central portion in the front-rear direction (left-right direction in FIG. 6) is closest to the fixed end in a side view, while the lower inclined surface 42B is lowest in the central portion. It is provided in the curved surface shape. Furthermore, the tip of each convex portion 36 is formed as a butting surface 43 located in a substantially vertical plane.

  The key holding tool 15 is provided so that the convex portions 36 and 36 are exposed in the slot hole 25 when arranged on the back side of the upper flat portion 22 in the inner case 13. Key K is held.

  As shown in FIGS. 8 and 9, an annular holder 50 (held portion) that functions as a key holder is inserted into the through hole K1 of the key K, and the annular holder 50 is held by the key holding tool 15. As a result, the key K is positioned on the lower flat surface portion 20 of the inner case 13.

  When the annular holder 50 is held by the key holding tool 15, the annular holder 50 may be opposed to the stepped portion 21 of the inner case 13 and the annular holder 50 may be pushed toward the slot 25 from this position. Thereby, the annular holder 50 is positioned at the center while being guided by the lower inclined surface 42 of each convex portion 36, and when a pressing force is further applied, the abutting surfaces 43, 43 of the respective convex portions 36, 36 are opened. The free end sides of the pair of holding bodies 35 are elastically deformed in a direction in which they are relatively separated from each other. Then, when the annular holder 50 passes through the tip of the convex portion 36, each holding body 35 is elastically returned to the initial position, and the abutting surfaces 43 and 43 abut each other and are closed. As a result, the key K is held by the key holding tool 15.

  In the state where the key K is held in this way, for example, when the fixed end of the holding body 35 is positioned above the free end, the annular holder 50 has its own weight between the annular holder 50 and the key K. As a result, it slides to the base side of one of the convex portions 36 (see FIGS. 2 and 9). Therefore, even if an unintended external force is applied in this state, the annular holder 50 is always caught by the convex portion 36 and does not drop carelessly. When the key K is removed, a person who operates the annular holder 50 can pull it out or pull it up while pulling it upward in FIG. 9 and pull it out.

  Therefore, according to such an embodiment, when the key holding tool 15 is positioned such that the fixed end of the holding body 35 is positioned above the free end, the annular holder 50 is provided on the base side of the convex portion 36. Therefore, even if a downward external force is applied to the key K, the annular holder 50 is caught on the convex portion 36, and the effect of effectively preventing the dropout can be obtained. In addition, the shape of the convex portion 36 is only slightly changed, and the configuration is not complicated.
