  However, in the outlet system 10 as described above, the position of the outlet unit 12 is indefinite. For this reason, the power cord 11 may be repeatedly bent at the position of the opening hole H on the floor surface F, resulting in disconnection.

  Further, the outlet unit 12 has a smaller height H in a direction perpendicular to the length L and the width W of the surface on which the plurality of power outlets 13 are located. For this reason, the outlet unit 12 movably disposed on the floor surface F is stable in a state where the power outlet 13 is positioned above. However, since dust easily enters the power outlet 13 in this case, for example, a fire may occur due to accumulation of dust.

  In order to solve the above-described problems, the outlet unit 12 may be fixed to the floor surface F in a state where the power outlet 13 is positioned forward. In such a case, for example, as shown in FIGS. 6 to 8, the outlet unit 12 is fixed to the floor surface F by the outlet fixing jig 20.

  The outlet fixing jig 20 is formed in a shape in which a bottom plate 21 and a rear plate 22 are continuous in an L shape. An opening hole 23 is formed in the rear plate 22, and a bolt 24 that is a screw member inserted through the opening hole 23 is fastened to the outlet unit 12.

  An opening hole 26 is also formed in the bottom plate 21, and a bolt 27 inserted through the opening hole 26 is fastened to the floor surface F. Further, a through hole 28 separate from the opening hole 26 is also formed in the bottom plate 21, and the power cord 11 is inserted into the through hole 28.

  When the outlet fixing jig 20 as described above is used, the outlet unit 12 is fixed to the floor surface F. For this reason, disconnection due to the power cord 11 being repeatedly bent at the position of the opening hole H of the floor surface F is prevented.

  Furthermore, since the outlet unit 12 is in a state in which the power outlet 13 is located on the front surface, it is possible to prevent dust from entering the power outlet 13. In addition, it is easy to connect the plug P of the power cord C of the electrical device to the power outlet 13.
