PROBLEM TO BE SOLVED: To provide a small-sized motor which materializes damping and silencing by contriving the structure so that the vibration from a stator core may be hard to be transmitted to a bearing holder. SOLUTION: This small-sized motor is equipped with a cylindrical bearing holder 3, a radial bearing 7 retained within the bearing holder 3, a rotary shaft 8 supported rotatably by the radial bearing 7, a rotor 10 including the rotor case 20 fixed to the tip side of the rotary shaft 8, a rotor magnet 21 attached integrally to the rotor case 20, and a stator core 5 fixed opposite to the rotor magnet 21. This motor has a core holder 25 which holds the stator core 5 by pinching it from both sides in axial direction, and the core holder 25 is fixed to the periphery of the bearing holder 3 by elasticity. The core holder 25 has a plurality of pressure contact parts 26 which pressure-contact with the bearing holder 3 by elasticity, and a coupling part 40 which connects each pressure- contact part 26 with the next.
