A yoke structure of a radial core type motor is provided to prevent the degradation of output and efficiency and the increase of an outer appearance and weight of the motor, by using a ferrite type magnet with weak magnetic force, in installing a magnet in a rotor rotating in the outside of a radial core. In a radial core type motor, a stator is installed along the circumference by being wound with a coil forming a magnetic field by being fixed to a body frame. A rotor(30) is installed with a magnet(54) rotating by interaction with the magnetic wave generated in the stator. A body part(52) has an installation groove where the magnet is to be installed. An air gap part is formed between the magnet and a magnet in an inner surface of the body part. A connection part(70) is used for connecting sides of the body part where the air gap part is formed.
