Sewing machine equipped with needle threading device
In a sewing machine equipped with a needle threading device, a thread holding tool includes: a thread holding surface part that guides and holds a thread; a thread pressing member that presses and sandwiches together with the thread holding surface part the thread; and a thread detachment preventing part that is provided to cross the thread which is sandwiched between the thread pressing member and the thread holding surface part. When passing the thread through the needle hole, a thread detachment preventing part regulates the thread so that the thread, which is sandwiched between the thread holding surface part and the thread pressing member of the thread holding tool, passes in a predetermined direction without deviating from a thread holding state.
