A pair of support members 4, 4 that are long in the vertical direction are installed on the back surface 1 </ b> A of the cabinet body 1 so as to face each other on the left and right. Further, a butterfly is provided on the right support member 4 so that the wiring covering cover 2 can open and close a space for covering the wiring of the electrical equipment housed in the cabinet body 1 by a one-side opening operation with the vertical direction as an axis. It is worn. The wiring covering cover 2 is a rectangular metal plate that is long in the vertical direction, and is provided with bent portions on the upper, lower, left and right edges.

  In addition, on the upper part of the left support member 4, a one-sided straightening member 3 which is a main part of the present invention is installed. Even if the left side of the wiring covering cover 2 is lowered by its own weight or the like when the wiring covering cover 2 is opened compared to the right side when the wiring covering cover 2 is opened, For correcting the left side of the covering cover 2 to a position where it is not lowered, it has a synthetic resin head 11 and a metal barrel 12 to which the head 11 is fixed. Become. The head portion 11 has a main body 13 formed in a cap shape that opens only downward and can be fitted into the upper end portion of the trunk portion 12, and a tapered portion 14 that projects integrally from the main body 13 forward. ing. And the upper surface of the taper part 14 is formed as the taper surface 14A which inclines and descends as it goes ahead from the upper surface of the main body 13 in series. A concave portion 15 is provided on the upper surface of the main body 13, and a screw hole 16 for screwing the head portion 11 to the upper surface portion 12 </ b> C of the trunk portion 12 is provided on the bottom surface of the concave portion 15.

  According to the cabinet having the above-described configuration, the one-sided straightening member 3 provided with the tapered surface 14A that gradually descends from the upper surface to the front is installed at the position described above on the cabinet body 1 side. Yes. Then, when the wiring cover cover 2 is rotated in the closing direction, the bent portion 2A of the wiring cover cover 2 comes into contact with the tapered surface 14A and moves upward on the tapered surface 14A, and finally the one-sided straightening is corrected. By riding on the upper surface of the member 3, the wiring covering cover 2 is closed in a state where it is not lowered. Therefore, even if the wiring cover 2 is lowered, the wiring cover 2 can be reliably closed.

  Further, a permanent magnet is housed in the trunk portion 12 of the one-sided straightening member 3 so that the front surface portion 12A of the trunk portion 12 is attracted to the rear surface of the wiring covering cover 2 when the wiring covering cover 2 is closed. It has become. Therefore, it is possible to maintain the wiring covering cover 2 in a closed state, and a rational structure that does not require a separate member for maintaining the wiring covering cover 2 in a closed state. can do.

  Instead of the one-sided straightening member 3, for example, one-sided straightening member 20 shown in FIGS. 6 and 7 can be employed. Similar to the one-sided straightening member 3, the one-sided straightening member 20 has a synthetic resin head 21 and a metal body 22 to which the head 21 is fixed. The head portion 21 has a main body 23 formed in a cap shape that opens only downward and can be fitted into the upper end portion of the trunk portion 22, and a taper portion 24 that protrudes forward integrally from the main body 23. ing. And the upper surface of the taper part 24 is formed as a taper surface 24A which inclines and descends from the upper surface of the main body 23 toward the front. However, screw holes 26 and 26 for screwing the head portion 21 to the upper end portion of the body portion 22 are provided on the left and right side surfaces of the main body 23.

In the space S2 surrounded by the front surface portion 22A and the left and right side surface portions 22B and 22B, a permanent magnet can be accommodated as in the case of the one-sided straightening member 3. The left side surface portion 22B is provided with a fixing piece 27 protruding outward (left side), and the fixing piece 27 has fixing holes 28 and 28 for fixing the one-sided straightening member 20 to the support member 4. It has been drilled. Further, screw holes 29 for screwing the head 21 are formed in the upper ends of the left and right side surfaces 22B and 22B, respectively.

  The one-sided straightening member 20 is assembled by fitting a head portion 21 into a body portion 22 in which a permanent magnet is housed, and integrating the head portion 21 and the body portion 22 with screws 10 and 10. Similarly to the one-sided straightening member 3, the upper portion of the left support member 4, that is, when the wiring covering cover 2 is closed, the taper surface 24 </ b> A faces the open side of the bent portion 2 </ b> A of the wiring covering cover 2. Furthermore, the upper surface of the main body 23 and the hinged side of the bent portion 2A of the wiring covering cover 2 are installed at the same height in the vertical direction.

  Since the one-sided straightening member 20 is installed in this way, when the wiring cover cover 2 is rotated in the closing direction, the rear end of the bent portion 2A of the wiring cover cover 2 contacts the tapered surface 24A. Then, after sliding on the taper surface 24A and moving upward, the bent portion 2A finally rides on the upper surface of the head 21 of the one-sided straightening member 20, and the front portion 22A of the trunk portion 22 The wiring cover cover 2 is adsorbed on the rear surface of the wiring cover cover 2 and is closed in a state where the wiring cover cover 2 is not lowered, so that the same effect as the above-described downward movement correction member 3 can be obtained.
