And the inclined surface of the movable member are in contact with each other, the elastic O-ring is expanded in diameter to make frictional contact with the inner peripheral surface of the sleeve of the bobbin, and the inclined surface of the fixed member and the inclined surface of the movable member. The elastic O-ring is configured so as not to contact the inner peripheral surface of the sleeve when the surface is separated from the surface.

て設けられるが、その形状は固定部材と同形状である必
要はなく、たとえばリング状のものでもよい。The cylindrical movable member is provided corresponding to the position and the number of the fixed members, but the shape thereof does not have to be the same as the fixed member, and may be, for example, a ring-shaped member.

る。[Operation] In the present invention, when the inclined surface of the movable member is separated from the inclined surface of the fixed member by the operating means, the elastic O-ring is deeply fitted into the inclined surface to reduce the outer diameter. Therefore, it does not come into contact with the inner circumference of the sleeve of the thread winding bobbin, and the thread winding bobbin can be inserted into and removed from the rotary shaft without any resistance.

い。When the action of the operating means is released with the thread winding bobbin inserted on the rotary shaft, the inclined surface of the movable member approaches the inclined surface of the fixed member due to the biasing force of the elastic means. As a result, the diameter of the elastic O-ring is increased by the inclined surface, and the outer peripheral surface of the elastic O-ring and the inner surface of the sleeve of the bobbin bobbin frictionally contact each other. By this frictional action, the bobbin is held so as not to slip out from the rotary shaft. Since the inner circumference of the sleeve of the thread winding bobbin is held in contact with the outer peripheral surface of the fixing member, the core of the thread winding bobbin does not swing during rotation.
前記弾性Ｏ−リングは摩擦係数が高いので、高速回転時
においても糸巻きボビンのスリーブ内周面との間にスベ
リが生じず、糸巻きボビンの空まわりを生じさせること
がない。Since the elastic O-ring has a high coefficient of friction, slippage does not occur between the elastic O-ring and the inner peripheral surface of the sleeve of the bobbin even during high-speed rotation, and the bobbin does not run idle.

A mechanism for (a) inserting a sleeve of a thread winding bobbin into an outer circumference of a rotary shaft to detachably mount the thread winding bobbin to the rotary shaft, and (b) fixing the rotary bobbin to the outer circumference. A cylindrical fixing member whose surface is in contact with the inner peripheral surface of the sleeve to support the bobbin, and one end surface of which is an inclined surface, and (c) is movable in the axial direction with respect to the rotating shaft. A cylindrical movable member that is inserted and has an end surface facing the inclined surface of the fixed member formed into an inclined surface; and (d) the movable member so that the inclined surface of the movable member approaches the inclined surface of the fixed member. (E) an elastic O-ring wound around a V-shaped groove formed by the inclined surface of the fixed member and the inclined surface of the movable member; and (f) the elastic force. The fixed member is moved by moving the movable member on the axis of the rotating shaft against the biasing force of the means. (G) the elastic O-ring expands in a state where the inclined surface of the fixed member and the inclined surface of the movable member are in contact with each other. The elastic O-ring is in contact with the inner peripheral surface of the sleeve when the diameter of the elastic O-ring is frictionally contacted with the inner peripheral surface of the sleeve of the bobbin and the inclined surface of the fixed member and the inclined surface of the movable member are separated from each other. A bobbin attachment / detachment mechanism that is configured not to.
