PURPOSE: To aim at the promotion of miniaturization and lightweightiness in a female joint part and the omission of a slip ring mechanism. CONSTITUTION: An output shaft 16 is projected out of a driving device to be composed of mounting a motor or the like on a holder to be supported in an irrotational state on a support member, while a tubular female joint 20, where a male joint 34 is to be fitted and vice versa, is clamped tight to this output shaft, and a lock member 25 is supported so as to make it retractable in a direction engaging or disengaging to or from a lock groove of the male joint inserted into the female joint from a window 24 pierced through a tubular wall of the female joint. An operating ring 28 consisting of a magnetic member to press directly or indirectly the lock member to being engaged with the lock groove is supported on an outer boundary of the female joint free of reciprocating slide motion to a lock member pressing position and a pressing releasing position, and then a slide motion driving solenoid coil 32 of the operating ring is supported on an irrotational holder. |
