ノイド。In a drive solenoid that pulls up and drives a presser bar that elastically presses a cloth presser downward against the throat plate of a sewing machine through a motion transmission means, one end of a plunger that is attracted to a coil is slidable in an airtight and axial direction. The rod speed adjusting mechanism is configured such that the plunger chamber is configured to accommodate a plunger chamber, and the plunger chamber is exposed to the atmosphere through an air communication passage having an orifice having a needle valve that allows the plunger chamber to be adjusted forward and backward. Presser foot drive solenoid for sewing machines.
