  On the other hand, the closing body 14 includes a held portion 14a held by the screw portion 13b and a closing portion 14b that closes either one of the two through holes 12a and 12b. The closing portion 14b extends upward in accordance with the shape of the countersunk portions 12c and 12d, and a substantially cylindrical base portion 14g inserted into the through hole 12a or 12b is continuously provided at the lower portion thereof. Then, a held portion 14a having a substantially C ring shape (substantially C shape in a plan view) protrudes from the side wall of the base portion 14g. The holding portion 14a side of the closing portion 14b is rolled into a mortar shape to form a countersink surface 14c of the head portion 13a of the screw 13, while the opposite side of the base portion 14g to the holding portion 14a is cut into a stepped shape. The recess 14f is formed by being omitted.

  The closure body 14 is formed by molding an elastic body having elasticity (for example, resin or the like) into a predetermined shape, and the held portion 14a formed in a substantially C-ring shape has a screw shape as shown in FIG. The vicinity of the boundary between the portion 13b and the head 13a is held by elastic force. At this time, a ring-shaped or spiral groove or protrusion that substantially fits the screw may be formed on the inner peripheral surface of the held portion 14a to suppress the dropout.

  Further, a pair of end portions 14d facing the cut portion of the C ring of the held portion 14a is provided with a tapered chamfer 14e. In the present embodiment, the chamfer 14e is formed in a tapered shape that expands toward the shaft end side of the screw portion 13b, and the cut portion of the C ring is inclined so as to face the head portion 13a side of the screw 13, By pressing the chamfer 14e against the side surface of the screw portion 13b, the interval between the cut portions of the C ring is widened so that it can be easily attached to the screw 13.

  As shown in FIG. 10, in the state where the closing body 14 is inserted into the through hole 12, the closing portion 14b is placed on the counterbore portion 12c and closes the through hole 12a, while the held portion 14a. Is inserted into the through hole 12b below the counterbored portion 12d. Therefore, the side surface 13c of the head portion 13a of the screw 13 directly comes into contact with the countersink portion 12d formed in the fixing portion 2. At this time, as shown in FIG. 10, the countersink surface 14 c formed in the closing part 14 b is substantially continuous with the countersink part 12 d of the fixed part 2 to form a mortar-shaped countersink shape as a whole.

The floor plate 4 and the frame 5 are positioned. A through hole 12a is formed inside the cylindrical protrusion 4b. Therefore, the protrusion 4b is formed in a substantially C shape in plan view by cutting out the portion of the through hole 12b. Here, the base portion 14g of the closing body 14 is cut out so as to be continuous with the peripheral wall of the protrusion 4b to form a concave portion 14f, whereby the floor outlet device 1 is placed on the box cover 17B. Further, the interference between the opening 19B of the box cover 17B and the closing body 14 is suppressed.

  According to the above embodiment, since the closing body 14 can be held by the screw 13, the closing body 14 rolls unintentionally, falls on the floor, or falls from the opening 19 </ b> A or the like to the lower floor side. There is an advantage that the handling becomes easier.

  Further, according to the present embodiment, it is possible to prevent the closing body 14 from intervening at least between the head portion 13a of the screw 13 and the countersink portion 12d of the fixing portion 2. It can be made smaller in plan view.

  Such a configuration is particularly effective in the case where the through hole 12 is covered by the top plate portion 10 as in the present embodiment, since the concave portion 11 and the top plate portion 10 can be made smaller.

  In addition, when screwing via a bushing as in the above prior art, durability of the bushing that can withstand the high pressing force associated with tightening of the screw is required. However, in the case of the present embodiment, the above-mentioned conventional structure is used for the closure body 14 by directly contacting the head portion 13a of the screw 13 with the fixing portion 2 (the countersink portion 12c or 12d). It is possible to prevent a high pressing force such as technology from acting. That is, in other words, according to the present embodiment, the pressing force acting on the closing body 14 by tightening the screw 13 can be reduced as compared with the related art, and the durability of the closing body 14 can be improved accordingly. .

  And when elastic bodies, such as resin and rubber | gum, are selected as a material of the obstruction | occlusion body 14, there exists an advantage that the sealing performance in the through-hole 12a or 12b by which the screw | thread 13 is not penetrated by the obstruction | occlusion part 14b can be improved.

  Further, according to the present embodiment, since the closing body 14 is elastically fitted to the screw 13, the state where the closing body 14 is held by the screw 13 can be obtained more easily.

  In addition, according to the present embodiment, since the held portion 14a is formed in a substantially C-ring shape, the screw 13 can be inserted through the cut portion of the C-ring, and the screw 13 is held by the held portion 14a. The state can be obtained more easily.

  Further, according to the present embodiment, since the pair of end portions 14d facing the cut portion of the C-ring of the held portion 14a is provided with the tapered chamfer 14e, the screw 13 can be more easily inserted into the cut portion. Thus, the state in which the screw 13 is held by the held portion 14a can be obtained more easily.

  Further, when the tapered chamfer 14e is expanded toward the axial end side of the screw 13 as in the present embodiment, the closing body 14 is inclined and moved along the axial direction of the screw 13. The screw can be inserted more easily into the cut portion of the C ring, and the state where the screw 13 is held by the held portion 14a can be obtained more easily.
