In addition, voice coil motor 5 need not be provided with the coil yoke in addition, and substitutes with Sewing machines head frame 2, so the coil 55 of the amount of thickness that has more the coil yoke of can reeling in coil shuttle 54.Thus, can increase voice coil motor 5 exportable thrusts.Therefore, when producing the voice coil motor 5 of the identical thrust of output, the voice coil motor 5 of present embodiment can be realized miniaturization.And, by realizing that miniaturization can realize lightweight, can realize the raising of the response of voice coil motor 5.And then, by making voice coil motor 5 miniaturizations, it can be built in Sewing machines head frame 2, can realize the miniaturization of Sewing machines.In addition, owing to can save, therefore can realize the reduction of cost voice coil motor 5 being arranged on the disposal that Sewing machines should carry out when outside (for example, protective cover etc. being set) for the voice coil motor 5 that the operator can not touched generate heat.
In addition,, can cut down number of components, therefore, can realize that the production cost of voice coil motor 5 descends by substituting the coil yoke with Sewing machines head frame 2.
In addition, though coil 55 can generate heat because of energising, but heat can promptly be delivered to Sewing machines head frame 2 with the degree that the coil yoke is not set, Sewing machines head frame 2 contacts with extraneous air, therefore, the heat of transmitting can be discharged into extraneous air, just can cool off Sewing machines head frame 2 immediately.Thus, the radiating efficiency of voice coil motor 5 is improved.
In addition, though voice coil motor 5 is arranged in the Sewing machines head frame 2,, can be implemented in the facilitation of the operation when voice coil motor 5 is assembled in Sewing machines head frame 2 by reducing number of components.
In addition, can shorten the interval of tension disk 3 and voice coil motor 5, support the drive rod 4 that is connected with them with bearing 56, therefore, can alleviate the load that acts on drive rod 4, the decline of the response that deflection, bending that can prevent drive rod 4 etc. causes, the reduction of mobile accuracy.
