Abstract
A rotary member inspection method of inspecting a rotation operation of a rotary member configured to rotate about a rotation shaft includes: causing the rotary member to perform forward rotation and thereafter perform reverse rotation; acquiring one or both of a difference value between a rotating torque at a time of the forward rotation of the rotary member and a rotating torque at a time of the reverse rotation of the rotary member, and an inertia force at a time of switching from the forward rotation to the reverse rotation of the rotary member; and determining whether a rotation failure of the rotary member is present based on one or both of the acquired difference value and the acquired inertia force and a threshold set in advance.
