本发明提供一种缝纫机的穿线装置及缝纫机，可从针孔更确实地抽出线。穿线装置包括：针杆支撑部，安装着针杆，所述针杆保持具有针孔的针；穿线轴，可上下移动且可转动地被支撑；线保持机构，由穿线轴保持，在针孔的前表面使线以成为水平的方式绷直；及穿线机构，由穿线轴保持，且具有穿线针钩，所述穿线针钩利用穿线轴的转动而在针孔中出没；且穿线针钩于前端部分具有捕捉线的捕捉部，捕捉部包含供线出入的线通路、及保持线的线保持空间，且线通路是以变得最窄的部分的宽度窄于线保持空间的宽度的方式形成。; a threading axis which is vertically movable and can be rotatably supported; a thread holding mechanism held by the threading axis and horizontally tenses the thread at a front surface of the needle eye; and a threading mechanism held by the threading axis and having a threading hook being in and out of the needle eye by rotation of the threading axis. Moreover, the threading hook has a catching portion for catching the thread at a front portion, and the catching portion includes a thread passage for the in and out of the thread and a thread holding space for holding the thread. The thread passage is formed in a manner that the width of the portion becoming the narrowest is narrower than the width of the threading holding space. |
