A threading apparatus for a sewing machine includes a moving mechanism for moving a threading member between a first position where the threading member is close to a needle eye and a second position where the threading member is away from the needle eye. The moving mechanism includes a moving actuating member, a transmitting actuating member, a transmitting string-shaped member, and a moving string-shaped member. The transmitting string-shaped member is moved in such a direction that the moving actuating member is moved from a non-operative position to an operative position when the operating member is operated so that the transmitting actuating member is moved. The moving actuating member is moved from the non-operative position to the operative position so that the moving string-shaped member is moved in such a direction as to draw the supporting member.
