MOTOR SHAFT GEAR, MOTOR UNIT AND IMAGE FORMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To solve a problem that when displacement (rocking) of a motor shaft gear in a radial direction can not be inhibited only by the rigidity of a motor shaft, there is possibility that failure of a motor itself, gears arranged near the motor shaft and the like will be caused.

SOLUTION: A motor unit 40 has: the motor shaft gear 163 provided with a stud tubular part 163b rotatably supporting a gear stud 53 which is arranged coaxially with the motor shaft 63; a flapper motor 62 with the motor shaft gear 163 fixed to the motor shaft 63; a flapper motor frame 61 supporting the flapper motor 62; and a drive frame 51 having a gear stud 53 and fixed to the flapper motor frame 61.
