Claims

[Scope of utility model registration request]

A holding member configured to removably hold a cloth support holding a cloth from above on a sewing table, and move the cloth relative to a seam portion to form a seam on the cloth. A cloth support attachment/detachment device for a sewing machine that supplies the cloth support to the holding member, wherein the cloth support has a plurality of engagement projections protruding in the thickness direction of the cloth support at its peripheral edge. and a corresponding engaging part that is removable in the front and back direction and movably engages with the cloth support locking part of the extrusion means disposed on the edge of the sewing table, and the holding member is The engaging portion is provided with a positioning recess on its lower surface that fits into the engaging protrusion, and the positioning recess is continuously opened toward the fabric support supply side with a difference, and is opened toward the fabric support supply side. is formed with an inclined guiding groove so that both inner walls thereof are opened wider than the engaging protrusion, and the cloth support is advanced toward the holding member on the sewing table by the extrusion means. The engagement protrusion is introduced into the positioning recess through the guiding groove, and after the engagement protrusion and the positioning recess are fitted, the extrusion means is retreated, whereby the corresponding engagement part and the cloth support are moved. A device for attaching and detaching a fabric support in a sewing machine, characterized in that it releases engagement with a body locking portion.
