Abstract
The sewing machine includes a sewing machine motor, a needle plate, a feed dog, a presser bar, a presser bar holder, an adjustment portion, a presser spring, a restriction portion, and a change member having a first member and a second member. In a first period in which a feed dog upper end is above a plate upper surface and the adjustment portion is spaced apart from the restriction portion, the adjustment portion contacts with the presser bar holder to cause the urging force of the presser spring to be transmitted to the presser bar. In a second period in which the feed dog upper end is beneath the plate upper surface and the adjustment portion contacts with the restriction portion, the adjustment portion is spaced apart from the presser bar holder to prevent the urging force of the presser spring from being transmitted to the presser bar.
