Abstract

To suppress noises, wear, breakage, or the like by reducing a load on a lower shaft gear to prevent the gear from swinging. A bearing mechanism of a lower shaft is equipped with a drive gear driven to make reciprocative rotations by a rotating upper shaft and a lower shaft gear which is provided on the lower shaft in a manner to be spaced a prescribed distance from one end of the lower shaft in parallel to the upper shaft to the inside and rotates the lower shaft by engaging with the drive gear. The bearing mechanism of a lower shaft is also equipped with a first bearing part which is located inside the lower shaft gear on the lower shaft and is mounted on a frame of a sewing machine by rotatably supporting the lower shaft to adjust the position of the shaft center of the lower shaft gear and a second bearing part located outside the lower shaft gear on the lower shaft to rotatably support the lower shaft. The second bearing part is mounted on the frame of the sewing machine to correspond to the position of the shaft center of the lower shaft gear.
