To provide a bobbin fixing device having a simple structure and capable of easily fixing a bobbin.
Inclined portions of pressing pieces 35 projecting to outside of a rotating shaft 23 are pressed by the bobbin 10 and the pressing pieces 35 are moved to inside positions P2. The bobbin 10 is inserted to a position where a positioning member 25 is arranged. When the bobbin 10 abuts on the positioning member 25, support members 34B are moved upwardly together with a release button 32 by a spring member 33. Along with the upward movement of the support member 34B sides of arms 34A, the pressing piece 35 sides are moved outwardly, so as to be protruded outwardly to positions where regulating faces 35C abut on the bobbin 10. At this time, the pressing faces 35B abut on the upper face of the bobbin 10, and movement in a direction (direction Y) in which the bobbin 10 comes out from the rotating shaft 23 is regulated.
