Abstract
A thread end holding unit of a sewing machine employs a needle thread gripping puller driven so as to be positioned either at a thread catch position or a return position. The puller has a hook portion at a tip end thereof adapted for catching a needle thread extended from a needle when the needle thread gripping puller is positioned at the thread catch position. The needle thread is caught and held by the hook at the return position. First and second holding members are respectively fixedly mounted on a supporter fixed to the arm. These holding members have press portions forcibly pushed elastically by both sides of the needle thread gripping puller for pressing and holding the thread end of the needle thread caught by the hook when the hook portion is positioned at the return position.
