Abstract

To secure a thread cutting mechanism having no projection from a needle plate, dispensing with the formation of a side swelling part on a cylindrical bed, easily and smoothly inserting a cylindrical portion in a cylindrical bed, performing a predetermined sewing, distributing a cutting load, and constantly providing superior cutting performance for a long period of time. A blade edge 16a of a fixed knife 16 and a free end 17a of a thread clamp plate 17 constituting a thread cutter 18 are formed diagonally linearly long along an inclination direction gradually separating from a cloth feed groove 14 toward the rear side of the cloth feed direction (a), so that the swinging across the full reciprocating drive swinging range of a movable knife 15 is clampedly guided between the fixed knife 16 and the thread clamp plate 17 while changing the contact point with the movable knife between a tip thread hanging part 15a and its base end part according to the reciprocating drive swinging of the movable knife 15. The fixed knife 16 and the thread clamp plate 17 are fixed to the rear face of the needle plate 5 in a state not to outward project from one side of the needle plate 5 having both sides 5a parallel to the cloth feed direction (a).
