A threading apparatus for threading a thread guide of a sewing machine includes a moving member, a pivot arm, and a hook member pivotally mounted on the moving member and coupled to the pivot arm so as to be operated in synchronization with the pivot arm. The hook member has a threading hook and performs a first rocking switching the hook member from a standby position where the threading hook is not threaded to an operating position, based on action of an operating force upon rotation of the pivot arm. The hook member further performs a sliding movement in which the hook member is slid from the operating position together with the pivot arm and the moving member to thread the thread guide and a second rocking in which the hook member is rocked to be returned to the standby position after having threaded the thread guide.
