Each of the handle portion upper plate 53 to the handle portion partition plate 58 is made of a synthetic resin integrally formed with the top plate 7, and is provided only on the top plate 7. For this reason, since the joint surface between the synthetic resin and the metal disappears from the left rear handle 51, the rigidity of the left rear handle 51 is improved. Since the top plate 7 of the outer case 1 is fastened to the rear plate 3 of the outer case 1 on the left and right sides of the left rear handle 51, the left rear handle 51 is connected to the left fastening pieces 63 and both left and right of the rear plate 3, respectively. Reinforced by each of the screws 66. In addition, the distance Wll from the inner surface of the handle left plate 56 of the left rear handle 51 to the center point of the left left screw 66 is set to be equal to or less than “½” of the width dimension Wl of the left rear handle 51. The distance Wlr from the inner surface of the handle right plate 57 of the rear handle 51 to the center point of the right left screw 66 was set to be “½” or less of the width dimension W1 of the left rear handle 51. For this reason, since the rigidity of the left rear handle 51 is further improved, when the operator inserts fingers into the left rear handle 51 and carries the outer case 1 as a whole, the top plate 7 is deformed to deform the front plate. 2, the rear plate 3, the left side plate 4, and the right side plate 5 can be prevented from floating.

  A left handle receiver 61 for supporting the handle lower plate 54 of the left rear handle 51 in a contact state from below is provided on the rear plate 3 of the outer box 1. For this reason, it is possible to prevent the left rear handle 51 from being tilted and deformed when the operator inserts fingers into the left rear handle 51 and carries the outer case 1, so that the top plate 7 is deformed. It is possible to prevent the front plate 2, the rear plate 3, the left side plate 4, and the right side plate 5 from being greatly lifted locally. The left rear handle 51 is provided with a left rib 69 and a right rib 70. For this reason, when the operator inserts his / her fingers into the left rear handle 51 to carry the outer case 1, the left rib 69 of the left rear handle 51 comes into contact with the left handle 61 from the left side. The plate 7 is prevented from moving to the right with respect to the rear plate 3, and the right rib 70 of the left rear handle 51 contacts the left handle 61 from the right so that the top plate 7 contacts the rear plate 3. On the other hand, since it is prevented from moving to the left, the top plate 7 is moved in the left-right direction so that gaps are generated in the front plate 2, the rear plate 3, the left side plate 4, and the right side plate 5, respectively. Can be prevented.

  Since the horizontal handle part partition plate 58 is provided inside the left rear handle part 51, when the operator inserts fingers into the left handle part 51 and carries the outer box 1, the handle part upper plate 53 and the handle part are provided. Both of the partition plates 58 can be gripped. For this reason, since it becomes easy to put force into a finger when an operator carries outer box 1, it becomes possible to carry outer box 1 easily. An upper rib 60 is provided on the handle upper plate 53 of the left rear handle 51, and the handle partition plate 58 is formed on the upper upper rib 60 in a natural state in which the handle divider 58 of the left rear handle 51 is not elastically deformed. It was made to oppose through a clearance gap, and when the operator carried the outer case 1, it was made to contact the upper rib 60 by making the handle part partition plate 58 elastically deformed upward. For this reason, compared with the case where the handle part partition plate 58 is not elastically deformed, the feeling transmitted to the fingers when the operator carries the outer box 1 becomes flexible. The above effects are the same for the right rear handle 52.

  In the first embodiment, both the handle part partition plate 58 and all the upper ribs 60 are eliminated from each of the left rear handle part 51 and the right rear handle part 52, and the left side when the worker carries the outer box 1. A configuration may be adopted in which the fingers are hung from below on the upper plate 53 of each of the rear handle 51 and the right rear handle 52.

  In the first embodiment, all the upper ribs 60 of the respective upper portions 53 of the left rear handle portion 51 and the right rear handle portion 52 are eliminated, and the left rear handle portion 51 and the right rear handle portion 52 are respectively removed. An upper rib that protrudes upward may be provided on the handle portion partition plate 58. The upper rib is opposed to the upper handle portion upper plate 53 through a gap in the natural state of the handle portion partition plate 58, and contacts the upper handle portion upper plate 53 in an elastically deformed state of the handle portion partition plate 58. To do.

In the first embodiment, the thickness dimension of the respective handle part partition plates 58 of the left rear handle part 51 and the right rear handle part 52 may be set to the same value as that of the inclined part 59 of the top cover 41.
In the first embodiment, each of the left rear handle 51 and the right rear handle 52 has a handle upper plate 53, a handle lower plate 54, a handle front plate 55, a handle left plate 56, and a handle right plate 57. Each thickness dimension of the handle portion partition plate 58 may be set to the same value as that of the inclined portion 59 of the top cover 41.
