PURPOSE: A rail road type insertion hole outlet capable of selecting a plug insertion hole and adjusting a gap is provided to freely adjust a gap between plugs. CONSTITUTION: All plugs located in an upper case of an outlet are inserted into a rail road type insertion hole. A U-type electrode circuit board safely holds a plug contact rode inputted through a rail road type insertion hole located in the upper case. Both upper parts of the U-type electrode circuit board are formed in an arc shape so that the plug contact rod is easily inserted into the U-type electrode circuit board. The U-type electrode circuit board is safely fixed in a lower case. A wire is safely connected to the U-type electrode circuit board.
