Cam adopted in the lateral position adjustment mechanism for the rotary hook base allows easy fine adjustments for clearance between needle and rotary hook point can easily be made, which greatly increases the efficiency of replacing gauge parts. Furthermore, a needle drop correction function (sideways) is provided, so that the needle drop position can still be adjusted to the center of the needle hole even if using commercially-available gauge parts. The gauge parts for previous models can still be used without any changes.
