Claims

[Scope of utility model registration request]

A box body to which electric wires are connected and which are buried in the floor concrete is connected with an electric wire conduit, and is provided with an extraction pipe whose upper surface is located on the same plane as the upper surface of the floor concrete and which takes out the electric wires from the box body. 1. A floor box for taking out electric wires, characterized in that a blind plug is attached to the pipe, the top surface of which is located approximately on the same plane as the top surface of the taking out pipe.
