PURPOSE:To join easily and surely split barrels as well as between them and with a main body barrel, by using a frictional force as well as an electro-magnetic force in the joining method of split resin barrels for a camera. CONSTITUTION:An inserting projecting part 4 is inserted into an inserting recessed part 5 along a spigot projecting part 7 and a spigot recessed part 8, and the spigot projecting part 7 is turned to a fitting completion position. In the fitting completion position, a pair of power supply terminals 14 are brought into contact with each other and electricity is conducted and when a current is flowed to coil wires 11 of electromagnets 6 through a conductive line 13, electromagnets 6 act, and a unifying force is generated between electromagnets 6 facing each other on the junction face. Thus, split resin barrels are joined easily, and a sure unifying force is attained together with the later action of the electromagnetic force. |
