A bobbin of a motor is provided to prevent a liquid filler from leaking outside by coupling a connection part of separated members through ultrasonic fusing. A bobbin of a motor includes a coil winding member(110) and a housing(120). The coil winding member is wound by a coil at the outer circumference thereof, and has coupling flanges(112) at both ends of a hollow winding part(111) into which an arm is inserted. The housing has a U-shaped cross section to have the coil winding member inside thereof, and forms a space for filling a filler by coupling both open sides thereof at the coupling flanges of the coil winding member with ultrasonic fusing.
