Abstract
A sewing machine includes a drive shaft rotated by a motor, a cam member fixed to the drive shaft and including a first cam and a second cam, a forked member including a main body member and an auxiliary member, an urging device, and a presser mechanism. At least one of a first cam surface of the first cam and a second cam surface of the second cam is inclined with respect to the drive shaft. The main body member and the auxiliary member are disposed to face each other such that the cam member is clamped between them. The urging device urges the main body member and the auxiliary member in a direction to clamp the cam member. The presser mechanism drives a presser member to hold a cloth, by swinging of the forked member caused by the rotation of the cam member.
