PROBLEM TO BE SOLVED: To provide a single-phase claw pole type motor for realizing increased productivity.SOLUTION: A single-claw pole type motor comprises: a stator 2 configured with stator core 4 including a first and second claw magnetic poles 4a, 4b to have an annular coil therebetween; a rotor 3 facing the stator 2 having an interval therebetween in a radial direction, and including a plurality of magnetic poles in a circumferential direction thereof. The interval in the radial direction is even in the circumferential direction, and density of magnetic materials in the first and second claw magnetic poles 4a, 4b is also even. The first and second claw magnetic poles 4a, 4b have a surface (a claw part 42) against the rotator 3 (a permanent magnet 32), and the surface has a pair of sides 420 and 421 extended in an axis direction. At least a part of the paired sides (in the axis direction) are formed in parallel. |
