造。[Scope of claim for utility model registration] (1) In a fixation structure with a rotating member such as a pinion gear or a rotor magnet, a hole drilled in the rotating member has a pinion outer diameter equal to or outside the pinion. A pinion shaft portion that is smaller than the tooth diameter and larger than the tooth bottom diameter is fitted into the hole of the rotating member in a loose fit or interference fit, and the pinion shaft portion is on the opposite side of the rotating member from the pinion portion. A fixing structure for a rotating member in which the outer diameter of the ring is fixed by welding the outer diameter of the rotating member to a hole of the rotating member that is in contact with the outer diameter. (2) A fixing structure for a rotating pinion and rotating member according to claim 1, wherein a portion of the pinion shaft and the rotating member hole that are not in contact with an outer diameter portion of the pinion shaft is melted. (3) The pinion rotating member fixing structure according to claim 1, wherein the cross-sectional length of the shaft portion of the pinion shaft portion is equal to or smaller than the cross-sectional length of the hole portion of the rotary member.
