A compact twister and a method for producing a twisted wire that can efficiently produce a short twisted wire that satisfies performance requirements, as well as a ply and a pneumatic tire twisted using the twister or the method for producing a twisted wire, are provided. The twister includes a rotating body 30 for twisting plural filament wires that are fed thereto to form a cord 20 and for applying a feeding force to the cord 20. The rotating body 30 includes a feeding mechanism 58 within a housing 31, and the cord 20 is discharged from the rotating body 30 by the feeding mechanism 58. The twister carries out twisting operation with one of a cord side of a twisting point or a filament wire side of the twisting point being free. Thus, a compact twister, that can form a cord 20 with excellent rotating property and straightness, can be accomplished.

The present invention provides a bobbin fixing device capable of fixing a bobbin easily with a simple structure and also provides a bobbin removing device capable of removing a bobbin readily with a simple structure. Stoppers 35 project from the level of the outer surface of a rotating shaft 23. Sloping surface of each stopper 35 is pressed by a bobbin 10, so that the stopper is moved to an inner position P2. The bobbin 10 is attached so as to position on a positioning member 25. When the bobbin 10 is brought into contact with the positioning member 25, each support 34B upwardly moves together with a release button 32 biased by a spring 33, so that one end of each arm 34A on the associated support 34B moves upward and the other end thereof close to the associated stopper 35 moves downward. Thus, each stopper 35 outwardly moves and projects until a restricting face 35C of the stopper 35 is brought into contact with the bobbin 10. At that time, a retaining face 35B of each stopper 35 is in contact with the top surface of the bobbin 10, thus restricting the movement of the bobbin 10 in the direction (Y direction) in which the bobbin 10 is removed from the rotating shaft 23.
