As a result, it is possible to inexpensively provide a socket device i1J with a cover from the outside of the socket device 1 to the inside. (3) The socket device i with a cover according to the present embodiment is configured such that the flat portion 85 of the second cover body 80 and the fourth flat portion of the periphery of the ground electrode insertion hole 12 of the rear surface 13a of the front wall 13 of the outer casing 1 are formed. 17 forms a surface contact. According to this configuration, the contact area between the flat portion 85 and the fourth flat portion 17 can be increased as compared with the case where the planar portion of the second cover body and the fourth planar portion are in line contact. Therefore, it is possible to suppress the foreign matter from invading the inside of the socket device 具 through the cover electrode via the ground electrode, in particular, by the torsion coil spring 83 as the biasing unit, toward the fourth plane behind the front wall 13 of the outer casing 10. Since the second cover body 8 is biased by the second cover body 8 , the flat portion 85 of the cover 2 is in contact with the fourth flat portion 17 while being pressed. Therefore, the gap between the plane portion and the plane portion 17 of the 19th 201021308 32063pif 4 can be reduced, or the gap can be eliminated, so that the foreign matter can be more reliably suppressed from being inserted from the ground electrode by the outside of the socket device 1 with the cover. The hole 12 intrudes into the inside through the above gap. (4) Preferably, the socket device J with a cover of the present embodiment is mounted in a water treatment circulating house such as a washstand or a system kitchen. When the socket device 1 with a cover of the present embodiment is mounted on a washstand and a system cabinet, it is difficult to assume that a large amount of liquid such as water is directly washed onto the socket device 1 having the cover, but it is conceivable that the self-cleaning is performed. The liquid splashed in the sink of the table or the sink of the system cabinet is attached to the socket device 1 with the cover. In this case, by providing the ground electrode insertion hole 12, even if the operator inserts the plug of the electric device into the socket device 1 with the cover with a water-soaked hand, the electric shock can be suppressed. Further, by providing the first cover body 70 and the second cover body 80 in the blade insertion hole 11 and the ground electrode insertion hole 12, it is possible to suppress the intrusion of liquid into the cover without using electrical equipment. Since the inside of the socket device 1 is provided, it is possible to further suppress the electric shock of the operator. (5) The socket device 1 with a cover of the present embodiment is configured as follows, and is provided with a fixing reed 50 for connecting electric wires to the blade receiving portions, respectively. According to this configuration, as shown in Fig. 8, when the socket device 1 having the cover is attached, the socket devices 1 having the cover can be connected to each other by the electric wires 5 to W8 which can be wired in the switch case 4. Therefore, it is possible to reduce the power supply side of the trim wire in the building material (inside the wall) (4): 2 = line W2 and the socket device with the cover! The connection part. As a result, when the construction of the house equipment (wall surface) such as the washstand is carried out in the building materials, the implementation of the power supply project for electrically connecting the 20 201021308 32063pif power supply side wire wi and the ground side wire W2 to the socket device with the cover can be reduced.

The flat portion 75 may be in surface contact over the entire circumferential surface of the peripheral edge of the tab insertion hole u. Therefore, the flat portion 75 may not abut against a part of the inner side in the longitudinal direction of the third flat portion. In the socket device 1 with a cover according to the present embodiment, the flat portion 75 of the first cover body 70 and the first flat portion 14 to the third flat portion 16' of the outer casing 10 are provided so as to extend perpendicularly to the front-rear direction. The shape is not limited to the shape of the flat portion 75 and the first flat portion 14 to the third flat portion 16. As long as the first cover body 70 is in surface contact with the peripheral edge of the front wall 13 of the outer casing 10 of the outer casing 10, the flat portion 75 is provided to protrude toward the rear of the front wall 13 of the outer casing 10. The protrusions are provided with concave shapes that are fitted to the projections of the plane portion 75 in the i-th plane portion 14 to the third plane portion 16. This point is also the same for the contact structure between the flat portion 85 of the second cover body 80 and the fourth flat portion 。. In the socket device 1 with a cover according to the present embodiment, a leaf spring 9 is used as a biasing means for biasing the first cover body 70 toward the outer casing 1a, but the biasing means is not limited thereto. As long as the first cover boat 21 201021308 32063pif 70 can be applied to the outer casing 10. Therefore, for example, a coil spring (e〇ilspring) may be used instead of the leaf spring 90. In the socket device 1 with a cover according to the present embodiment, the blade insertion hole 11 and the ground electrode insertion hole 12 are provided in the casing 1A, but the insertion hole provided in the casing 10 is not limited thereto. For example, only the blade insertion hole 11 may be provided in the outer casing 10. Although the present invention has been disclosed in the above embodiments, it is not intended to limit the invention, and those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
