PROBLEM TO BE SOLVED: To make a circuit body so as to be monthly expanded or contracted with the opening or closing the door. SOLUTION: A circuit body 24 is stored in a circuit body storage space in a door as in a nearly S-shaped manner. A protector 27 with a connector 28 in succession to this circuit body is made into being free of advance or retreat, while a circuit l:>:>dy stationary part 26 is installed in front of the circuit pbody storage space, a guide roller is installed in a rear part of the protector, and the circuit body is set up in the protector by way of a roller from this stationary part 26. In brief, the. stationary part 26 and the guide roller 23 both are installed in front of the circuit body storage space, and this roller 23 is situated on the inside of the protector 27, holding the circuit body down with the roller 23. In succession, a pinion 34 is installed in the roller 23, then a rack 39 is installed in the protector 27. In addition, a support roller 35. is installed in the roller 23, making it pinch the circuit body. In this case, it will do that the roller 23 may be energized in the circuit body pinching direction with an elastic member. The stationary part 26 is provided with a curved surface in contact with the circuit body 24. Since the circuit body storage space is a circuit body storage case 21, a circuit body roping groove is installed in this storage case 21, thereby locking the circuit body 24 at the case rear part.
