である。According to the first aspect of the present invention, there is provided a rotating portion (such as a hand pulley shaft 2, a hand pulley 4 and a hand pulley gear 6) for performing a predetermined rotation, and the rotating portion has the rotating portion. A rotary shaft operating unit (hand side) which is connected to an operating shaft (pulley shaft 2 at hand) serving as a center of rotation of the sewing machine and a predetermined rotating shaft (upper shaft 14) of the sewing machine to rotate the rotating shaft by rotating the operating shaft. A pulley gear 6) and a handle portion (hand pulley 4) for manually rotating the operating shaft are provided, and a convex portion (hand pulley roller 7) extending from the rotating portion and the operating shaft are A locking portion (hand pulley metal 3) having a concave portion (notch 12) with which the convex portion engages at a predetermined rotation angle and locking the rotation of the rotating portion by the engagement; An elastic member (hand pulley return spring 9) for urging the moving part in the axial direction of the operating shaft, and the rotating shaft is a needle. Alternatively, the elastic member is connected to a predetermined needle bar driving mechanism to reciprocally drive the needle bar, and the elastic member urges the rotating part in a direction to release the connection between the rotating shaft operating part and the rotating shaft. The concave portion is formed on a surface of the engaging portion in the radial direction of the operation shaft, and the convex portion rides on the surface of the engaging portion against the biasing force of the elastic member. The rotary shaft operating portion is connected to the rotary shaft when the rotary shaft operating portion is engaged, and the rotary shaft operating portion and the rotary shaft are disconnected when the convex portion is engaged with the concave portion. , Manual rotation device for rotary shaft of sewing machine (1)
It is.

より異音が生じることはない。According to the rotating shaft manual rotating device of the sewing machine of the first aspect, the predetermined rotating shaft and the rotating shaft operating portion are connected, and the convex portion is engaged against the biasing force of the elastic member. Even if the rotating shaft rotates due to the activation of the sewing machine while riding on the surface of the part, while the rotating part makes one rotation in conjunction with this rotation,
By the biasing of the elastic member, the convex portion falls into the concave portion, the rotation of the rotating portion is locked, and the connection between the rotating shaft and the rotating shaft operating portion is released. As a result, the rotation of the rotating shaft immediately stops the rotation of the handle without rotating more than one rotation. Also,
When the connection between the rotary shaft and the rotary shaft operating unit is released,
Since the rotating portion is locked by the engagement of the convex portion and the concave portion, no abnormal noise is generated by the vibration.
