Abstract

Provided is a technique for identifying a lubrication state of a contact unit in an actuator (10) including a motor (14) and a speed reducer. An actuator (10) including a motor (14) and a speed reducer (16), includes: a contact unit (60A to 60F) including a plurality of contact members, in which during an operation of the actuator (10), the contact members adjacent to each other come into contact with each other with relative movement; a plurality of energization members (66A, 66B) provided separately from the contact unit (60A to 60F) and configured to cause an electric current to flow through an energization path (64) configured by a plurality of actuator constituent members via a contact location between the plurality of contact members; and a measurement unit (62) configured to measure a lubrication state between the plurality of contact members in the contact unit (60A to 60F) by causing an electric current to flow through the energization path (64).
