Abstract
A presser device for a sewing machine is disclosed. The presser device includes a presser bar; a presser foot provided at a lower end of the presser bar; a presser spring elastically biasing the presser foot downward; a presser-foot lifting lever moved between a lifted position and a lowered position for lifting/lowering of the presser foot; a speed restraining element producing resistance capable of slowing down the movement of the lever; and a speed-restraint switch mechanism that slows down the movement of the presser-foot lifting lever by allowing the speed restraining element to produce the resistance when the presser-foot lifting lever is moved from the lifted position to the lowered position, and that does not slow down the movement of the presser-foot lifting lever by not allowing the speed restraining element to produce the resistance when the presser-foot lifting lever is moved from the lowered position to the lifted position.
