A lower thread winding device is structured such that it comprises: lower thread supply means for guiding a lower thread out from a lower thread supply source and also for supplying the lower thread to a bobbin through an opening formed in a bobbin case; bobbin rotate means including a rotary body disposed on a bobbin within the bobbin case in such a manner as to be contactable with and separatable from the bobbin, the bobbin rotate means being capable of rotating the bobbin due to mutual contact between the rotary body and bobbin to thereby wind the lower thread around the bobbin; and, a thread handling member, after completion of winding of the lower thread around the bobbin, for handling a lower thread extended from the bobbin case to the lower thread supply source to thereby guide the lower thread from the opening of the bobbin case up to a slit formed in the peripheral side surface of the bobbin case. The lower thread winding device is characterized in that, when the thread handling member guides the lower thread, the pressing forces of the rotary member and bobbin against each other is weakened to thereby set them in a half-clutch state.
