Hereinafter, the operation of the present embodiment will be described. First, in order to grip the storage case 1 with the cantilever hanger 2, as shown in FIG. 4, the operation handle 15 and the arm 11 are gripped with both hands, and the gripping body 7 is placed on the side wall 4 side of the storage case 1. When the inner surface 7b is pulled down along the outer surface of the vertical piece 5b from above as shown in FIG. 5, the inner surface of the inner piece 10b of the engaging portion 10 slides on the outer surface of the vertical piece 5b, and As shown by a two-dot chain line in FIG. 3, the joint portion 10 is temporarily rotated outward (clockwise in the drawing) from the opening window 9 against the spring force of the torsion spring 13. Then, FIG.
When the holding portion 8 is fitted to the upper end portion 5 of the storage case side wall 4 by being lowered as it is, the engaging portion 10 is simultaneously turned inward from the inside of the opening window 9 by the spring force of the torsion spring 13 as shown by the solid line in FIG. The inner upper edge 10f of the engaging portion 10 abuts against the outer surface 4b of the side wall 4 and the upper end piece 10c of the engaging portion 10
Of the vertical piece 5b is closely opposed to the lower edge 5c of the vertical piece 5b. In this state, the outer piece 10a of the engagement portion 10
Are in a substantially vertical state in the opening window 9, so that the lower end edge 5c is engaged and supported from substantially vertically downward by the upper end piece 10c.

Next, when the storage case 1 is lifted via the arm 11 in the engaged and supported state, the upper end piece 10c of the engaging portion 10 comes into contact with the vertical lower end edge 5c, and further, the inner surface of the lower end portion of the gripping body 7 7 b presses against the leading edge of the support piece 6. Therefore, the storage case 1 tries to rotate in the counterclockwise direction (M direction) around the gripping body 7 as shown in FIG. 3 due to the vertical load F, but the holding portion 8 moves up the entire outer surface of the upper end portion 5. And the upper end piece 10 of the engagement portion 10
c engages and supports the lower edge 5c of the vertical piece 5b from below,
Furthermore, since the lower end of the holding body 7 supports the support piece 6 in the horizontal direction and the entire side wall 4 is effectively supported in each direction, the counterclockwise rotation thereof is reliably prevented.
That is, at this time, the vertical load F and the rotational moment M of the storage case 1 are particularly affected by the inner wall 8 b of the holding portion 8 with respect to the inside of the upper end 5 of the side wall 4 and the lower end of the gripping body 7 with respect to the support piece 6. It acts as an upward supporting force on the storage case 1 by the supporting frictional force, and is distributed and supported as a whole by the supporting force from below by the upper end piece 10c of the engaging portion 10 with respect to the upper end portion 5, so that it is reliable and stable. The support is obtained, and the rotation in the counterclockwise direction and the falling down can be reliably restricted.

In particular, since the engaging portion 10 supports the lower end edge 5c of the vertical piece 5b from below vertically by the outer piece 10a, strong support is obtained. Further, it is formed in an isosceles triangle, and the lengths L1 and L1 between the respective edges of the side pieces 10a and 10b from the top 10d are changed from the top 10d to the upper end piece 10
Since the length L2 is longer than the length L2 to the center of the upper case 10c, when the storage case 1 is lifted as shown in FIG. A strong engagement support state can be obtained while being locked to the lower end edge 5c and further rotation is reliably restricted.

Next, the storage case 1 supported by the cantilever hanger is conveyed from one place to another by an electric hoist or the like, and is arranged and arranged in another place. To remove from 1,
As shown in FIG. 6, with the storage case 1 placed on the floor,

Next, by holding the operating handle 15 with the other hand and lifting and rotating the entire cantilever hanger, the fitting of the holding portion 8 to the upper end portion 5 is released. As described above, since the release can be easily performed simply by rotating the release lever 14 and the operation handle 15, the release operation efficiency is improved.

FIG. 7 shows a second embodiment of the present invention.
This is a type in which the supporting piece 6 is not formed in the storage case 1, and a supporting portion 16 that is bent inward is integrally provided on an inner surface side of a lower end portion of the holding body 7. Therefore, when the storage case 1 is lifted, the distal end surface 16a of the support portion 16 supports the lower end of the side wall 4 of the storage case 1 from the horizontal direction. The other parts are the same as in the configuration of the first embodiment.

The present invention is not limited to the configuration of the above-described embodiment. For example, the release lever 14 is formed in a simple elongated plate shape and the lower end is formed on the outer piece 1 of the engaging portion 10.
0a, and the upper end portion is extended upward along the outer surface of the outer wall 8b of the holding portion 8, and the engagement is released by holding the upper end portion and operating forward. Is also possible. Further, the upper end portion 5 of the storage case may be formed in a horizontal U-shape with an open outer portion.
