  FIG. 6 shows a device 13 which is a comparative example with respect to the present embodiment. When the left and right grips 21 and 22 are shaped so that they can be gripped by either the left or right hand as in the device 13, the right grip 22 can be gripped by the right hand and the left grip 21 can be gripped by the left hand. There is a possibility that the worker will try to work. On the other hand, in the apparatus 11 according to the present embodiment, by providing the obstructing members 25 and 26 in the vicinity of the grip portions 21 and 22, it is possible to perform work by two or more people.

  Next, a lock mechanism in the device 11 will be described. If the device 11 is inadvertently pulled out from the rack 1, the device may fall, resulting in injury to the operator or damage to the device. Therefore, when the device 11 is pulled out from the rack 1 to some extent, a lock mechanism is provided so that the device 11 cannot be pulled out further unless the lock is removed, thereby preventing the device 11 from falling off the rack 1.

For this reason, work can inevitably be performed by a plurality of personnel, and safety can be ensured.

  Further, the housing of the device 11 disclosed in the present embodiment can be prevented from falling by providing a lock mechanism. In particular, by providing an operation member on the side plate for releasing the lock, the lock cannot be released when a single worker holds the left and right gripping portions, so that two or more workers can perform the work. Can do. In addition, by providing a lock mechanism on each of the left and right side plates, it is possible to ensure that two or more workers are working and to further prevent fall prevention and avoid injury.

  In this way, by allowing multiple workers to perform work, for example, the center of gravity of the device is biased, and even if the worker does not know that the center of gravity is biased, the device can be safely stored and pulled out without breaking the balance. Can be performed.

  FIG. 12 is an explanatory diagram of an apparatus according to the second embodiment. The device 12 according to the second embodiment is different from the device 11 according to the first embodiment in the shape of the lock fitting 42 and the shape of the side plate and the bottom surface portion. Other configurations are the same as those of the apparatus 11 of the first embodiment. That is, the device 12 is housed in the rack 1 and has left and right grips 21 and 22 on the surface member 20. The left grip 21 is defined to be gripped with the right hand and the right grip 22 is gripped with the left hand according to the dimensional relationship between the left and right grips 21 and 22 and the left and right side plates.

  FIG. 13 is an explanatory diagram of the shape of the lock fitting 42. The lock fitting 42 includes a fixing member 54, a guide member 63, a lock member 72, and an operation member 59. The fixing member 53 has a slide hole 57. The lock fitting 42 is slidably fixed to the outside of the side plate of the device 12 by inserting a screw, a rivet or the like through the slide hole 57.
