An electrically connectable joint mechanism is provided to heighten the reliability of control signals by having no necessity of separate electric wiring, and to control a joint movement only with mechanical combination by not making the mechanical movement of a joint mechanism interfered with electric wiring. An electrically connectable joint mechanism comprises a first frame(10) and a second frame(20) provided with contact terminals(15,25) to transfer electric signals to fastening portions(11a,21a) where a fastening joint is fastened to be transmitted with electricity, and a fastening joint(30) connected to the frames mechanically and provided with a signal line(33) to contact with the contact terminals and to connect a pair of the frames electrically.
