Claims

[Scope of utility model registration request]

A part of the rotational power transmission shaft is eccentric, an output member is assembled to the eccentric part, and a member is provided at both axial ends of the output member for holding and positioning the output member. An unbalance correction device for an electric motor, characterized in that the center of gravity of a holding and positioning member is shifted with respect to the axis of a rotating shaft to correct an unbalance between an eccentric shaft and an output member.
