PURPOSE: A single phase vibrating motor is provided to easily determine a stopping position of a rotating member due to interaction between a magnetic member and a permanent magnet by preventing the rotating member from being inclined to one side by magnetic force between the magnetic member and the permanent magnet. CONSTITUTION: A floor member(110) includes a shaft(130) and a permanent magnet(140). A rotating member(150) is rotatably coupled at the shaft. A coil member(160) is arranged in one side of the rotating member. A mass member(170) is integrally formed at the coil member and increases a size of the weight eccentricity of the rotating member. A magnetic member(180) is arranged at the rotating member and determines a stopping position of the rotating member.
