PROBLEM TO BE SOLVED: To provide a conductive joint device enabling stable conduction without enlarging a sliding side conductive material and a fixed side conductive material more than necessary.SOLUTION: A contact part 23a of a sliding side conductive material 23 is exposed to a tip of a spherical part 21, and a led out part 23b is electrically connectable to other part. A conduction part 28a of a fixed side conductive material 28 is exposed to a central part of a bottom of a recessed part 26 and electrically connected to the contact part 23a all the time, and a connection part 28b is electrically connectable to other part. Thus, without enlarging the contact part 23a of the sliding side conductive material 23 or the conduction part 28a of the fixed side conductive material 28 more than necessary, electrical connection can be easily obtained. Regardless of a turning angle, a contact area between the contact part 23a of the sliding side conductive material 23 and the conduction part 28a of the fixed side conductive material 28 is not changed, so as to enable stable conduction between the sliding side conductive material 23 and the fixed side conductive material 28. |
