The lock mechanism includes a support member configured to rotatably support the second frame such that a posture of the second frame with respect to the first frame to clamp the sewing object is switchable to a first posture and a second posture. The first posture is a posture in which a first surface of the second frame faces the first frame. The second posture is a posture in which a second surface of the second frame faces the first frame. The second surface is on the opposite side to the first surface. The lock mechanism is configured to press the second frame in at least the first posture toward a first frame side with respect to the second frame.

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.
