Abstract:
There is provided a sewing device comprising a needle and a looper, the sewing device including a rotation shaft that rotates the looper, and a set bolt that has a conical distal end and positions the looper in an axial direction relative to the rotation shaft from a radial direction of the rotation shaft, in which the looper includes a through screw hole into which the set bolt is screwed, the rotation shaft includes a groove recessed from a peripheral surface of the rotation shaft, and the groove includes an inclined surface that the distal end of the set bolt contacts. In one aspect, in the sewing device, a cross section of the groove viewed in a direction along an axis of the rotation shaft has a V shape. As a result, a relative position between the needle and the looper can be positioned with significantly high accuracy.
