<p>PROBLEM TO BE SOLVED: To provide a small motor which eliminates the need of a through hole at the rotor center, increases motor output with a smaller diameter structure, shortens an axial length, and reduces the number of components to improve the productivity.SOLUTION: A small motor includes: a rotor 10 having a magnet; an output shaft 20 which is connected with the rotor 10 so as to integrally rotate with the rotor 10; a connection member 30 which is located between the rotor 10 and the output shaft 20 and connects the rotor 10 with the output shaft 20; a coil 50 which is provided around the rotor 10 and through which a current may flow; and a housing 60 which covers peripheries of the rotor 10 and the connection member 30. An outer peripheral surface of the connection member 30 is formed so as to be larger than an outer diameter of the rotor 10. The outer peripheral surface is rotatably supported by an inner peripheral surface of the housing 60.</p> |
