ABSTRACT:
A sewing machine includes a mounting member, a needle bar driving mechanism, and a needle thread take-up driving mechanism. The mounting member has two sides mounted on the left and right of the needle bar driving mechanism and the needle thread take-up driving mechanism, respectively. The mounting member is supported on one of the sides by the main shaft, a rotating shaft rotated with the main shaft or a bearing member for the main shaft or the rotating shaft so that the mounting member is rotated relative to the machine frame and the main shaft or rotating shaft. The mounting member is supported on the other side by the main shaft or a supporting shaft substantially concentric with the rotating shaft and extending in a same direction as the rotating shaft so that the mounting member is rotated relative to the machine frame and the main shaft or rotating shaft.
