A stepping motor type indicator provided with unambiguous stable points having a holding force in a non-excited condition sufficient to suppress undesirable movements of a pointer. The stepping motor type indicator includes a stepping motor (,) having a rotor (,) with an output shaft (,) and stators (A, B). Yokes (,) have a plurality of pole teeth (,) extending toward curved outer surfaces of the rotor. The pole ends of a specific pole tooth (,) chosen from one of the plurality of pole teeth is made to have a pole end area different than that of the remaining pole teeth. This structure produces unambiguous stable points (&ldquo;a&rdquo;-&ldquo;l&rdquo;) and produces strong holding forces so that an attractive force exerted by the stable point (&ldquo;a&rdquo;) on the pointer (,) toward stopper pin (,) is increased to positively suppress undesirable movements of pointer (,).
