請求の範囲第１項記載の振巾調整機構。[Scope of claims for utility model registration] (1) A zigzag cam that rotates in conjunction with the main shaft,
In a zigzag sewing machine that has a follower that engages with the cam and is configured to transmit the movement of the follower to the needle bar, the zigzag cam 2 moves radially inward from the high surface 2b toward the low surface 2a. A swing width adjustment mechanism having a regulating means that can be engaged with a follower and whose engagement position can be adjusted in the radial direction by a manual operation mechanism. (2) The swing width adjustment mechanism according to claim 1, wherein the regulating means is a swing width control cam 5 concentric with a zigzag cam rotated by a manual operation mechanism. (3) The swing width adjustment mechanism according to claim 2, wherein the swing width control cam is a grooved cam whose groove width gradually changes. (4) The swing width adjustment mechanism according to claim 3, wherein the minimum groove width portion is formed to such a groove width that the fitted follower cannot move in the radial direction. (5) The swing width adjusting mechanism according to claim 1, wherein the regulating means is a tongue piece 19 projecting from a slide plate 18 that is movable only in the radial direction. (6) The swing width adjusting mechanism according to claim 1, wherein the regulating means is one end surface of a bell crank-shaped lever 21 pivoted by a manual operation mechanism.
