Abstract
A stepping motor includes a first plate; a second plate having a side facing the first plate and a reverse side; a stator held by the first plate and the second plate axially; plural band connecting portions equipped in the first plate, disposed at a side surface of the stator, extending toward the second plate and having an engaging portion at an outer side thereof; and a band portion contacting the reverse side of the second plate, extending toward the first plate and having plural arm portions engaging respective engaging portions of the band connecting portion. The band portion is connected to the first plate while holding the second plate and the stator therebetween by engaging the plural arms with the engaging portions, the band portion is elastically deformed, the deformation causes tensile force in which the arm portions pull the band connecting portions toward the band portion.
