PROBLEM TO BE SOLVED: To provide a cloth feed bar device of a post-bed type sewing machine permitting easy replacement of the device without requiring push-down of the sewing machine. SOLUTION: A rotating shaft is mounted at the upper end of an arm on the bottom of the feed device including a cloth feed bar, and a semicircular recess tub is formed at the lower end of the cloth feed bar. The axis of the rotating shaft and the center of the semicircle which face each other are superimposed and jointed to each other. A clasping projection fixed on one side of the lower end of the cloth feed bar clasps the outer periphery of the rotating shaft to restrain the vertical and horizontal movement of the rotation shaft. An upper/lower separation type cloth feed bar is adopted as the cloth feed bar, and an overlapping part is formed in the upper and lower cloth feed bar portions. As an eccentric shaft is disposed in the overlapping part, the cloth feed bar can be moved upward/downward and the minute adjustment is possible in the sewing. COPYRIGHT: (C)2006,JPO&NCIPI
