Abstract

In a sewing machine, a feed dog feeds a workpiece placed on a throat plate. A presser bar has a lower end portion on which a presser foot is mountable. A presser bar spring urges the presser bar downward. During a first prescribed period of time in which a top of the feed dog is above a top surface of the throat plate, an adjustment part of an adjusting mechanism is spaced apart from a restricting part of the adjusting mechanism to cause an urging force of the presser bar spring to be transmitted to the presser foot. During a second prescribed period of time in which the top of the feed dog is beneath the top surface of the throat plate, the adjustment part is in contact with the restricting part to prevent the urging force of the presser bar spring from being transmitted to the presser foot.
