ABSTRACT:
A presser device for a sewing machine includes a first lever having a cloth pressing portion which is swingably mounted on a presser foot, the cloth pressing portion being swung so as to be switchable between a cloth pressing position and a raised position, a second lever having a support portion where the second lever is pivotally supported on an upper part of the first lever and an abutment which is normally in abutment with a needlebar assembly moved up and down, a first biasing member which biases the first lever so that the first lever is caused to pivot in such a direction that the cloth pressing portion becomes a cloth pressing position, and a second biasing member which biases the second lever so that the second lever is caused to pivot in such a direction that the abutment of the second lever is abutted against the needlebar assembly.
