にホルダ主体１に連結する。 When the locking pin e engages in the groove 4, the left and right elastic divided pieces 3, 3 close the cut groove 2 to the old position by their elasticity, so that the lock pin e does not come out of the cut groove 2 unnecessarily. To securely connect a presser foot main body d to a holder main body 1.

次に指先にて押え金主体ｄを押し下げつつ引き
