Abstract
The presser foot for a sewing machine is provided with a pair of aligned rollers arranged near the needle dropping hole. The lower end portion of the presser foot holder is connected to the presser foot between the pair of aligned rollers, so that a sufficient downwardly pressing force may be applied on the sewn materials even in the region near the needle dropping hole.
