To provide a motor capable of preventing a damage to a coupling part of two coil bobbins disposed on top of each other, while securing a relative position accuracy of these coil bobbins.SOLUTION: A motor comprises two coil bobbins each having a circular shape. Each coil bobbin includes: a cylindrical trunk part on which a wire is wound; and a flange part provided at opposite ends of the trunk part. The two coil bobbins are arranged so as to vertically overlap, and a pair of opposite flange parts of the two coil bobbins has a coupling part expanded outwardly in a radial direction from one part of its periphery. In the coupling part of one coil bobbin, a boss part projecting to a coupling part side of the other coil bobbin is formed, and a boss hole corresponding to the boss part is formed in the other side coupling part as a coupling part of the other coil bobbin.
