  • Figs. 7(a) and 7(b) show a partial cross-sectional shape and a side shape of the lower support receive part 51 a and the upper support receive part 51g provided on the sinker 51 in Figs. 5(a) and 5(b) , respectively.
  • Figs. 7(c) and 7(d) show a side shape and a partial cross-sectional shape of the lower sinker support part 45d and the upper sinker support part 45g provided on the needle plate 45, respectively.
  • Fig. 7(a) shows a cross section cut along a cross-sectional line A-A in Fig. 7(b).
  • Fig. 7(d) illustrates a cross section cut along a cutting-plane line D-D in Fig. 7(c) .
  • the upper support receive part 51g is formed by offset bending process so as to be deviated from the lower support receive part 51a in the thickness direction as the direction of the axis line 51i.
  • the upper sinker support part 45g can be formed on the thin thickness part 45b of the needle plate 45. If the offset bending is not performed, the upper sinker support part 45g should be also formed on the thick thickness part 45a and manufacturing of the needle plate 45 becomes complicated.
