PURPOSE: A motor having a noise reducing housing is provided to reduce noise rather than the prior mass production product, by using a simple work introducing a rugged structure on the shape of a bottom surface of the housing. CONSTITUTION: A housing (1) has a cylindrical shape whose top is open. A stator core is fixed and combined to an inner space part of the housing, and forms an inner circumference of the housing. A rotor is constituted with a rotor core and a magnet, and is installed in the stator core as being able to rotate. When a current is applied to the stator, the rotor is rotated by electromagnetic interaction between the stator and the rotor, and a rotation axis rotates by being linked to the rotation of the rotor. A noise prevention part (100) is formed to be protruded with a certain height on the bottom surface of the motor housing, and is arranged at a position facing with a coil winding part.
