Abstract (en)
[origin: EP2261946A1] To reduce the number of parts and reduce the price by forming an armature support portion (4a) integrally with a stator (4), and secure a sufficient magnetic attractive force by making the support portion (4a) a cantilever structure so that no magnetic path forms across a fulcrum portion. By providing a support portion on a stator (4), the fluctuation in the size of a gap between an armature (6) and the stator (4) is reduced, and the magnetic property is stabilized,
