PROBLEM TO BE SOLVED: To provide a cylindrical motor capable of attaining high output, and slimness, especially in the radial direction. SOLUTION: This cylindrical motor comprises a magnet which is formed into a cylindrical shape and at least, of which an outer periphery is divided in the circumferential direction and polarized alternately for different poles, a first bobbin wound with a coil, a second bobbin wound with a coil, a first outer pole energized by the coil wound around the first bobbin and facing an outer periphery of one end of the magnet, a hollow and roughly-cylindrical first inner pole facing the inner periphery of the magnet, a second outer pole magnetized by the coil wound around the second bobbin and facing an outer periphery of the other end of the magnet, and a hollow and roughly-cylindrical second inner polar part facing the inner periphery of the magnet. The magnet is formed with a hollow fitting part fitted so as to be slidable on a fitting member provided on the first or second inner pole.
