Claims

[Claims for Utility Model Registration] An outer hook having a rotating axis, an inner hook that is housed in the outer hook, and an inner hook that has a protrusion that fits into a recess formed in the inner hook and prevents rotation of the inner hook. a rotation preventing member, of each pair of opposing surfaces of the protrusion and the recess;
A pair of opposing surfaces that come into contact during rotation of the outer hook are formed parallel to the axis of rotation, and the other pair of opposing surfaces are formed parallel to each other and inclined in a direction away from the axis of rotation, A full-rotation hook for a sewing machine, characterized in that the inclined opposing surfaces are spaced apart from each other at intervals during rotation of the outer hook.
