摘要

PROBLEM TO BE SOLVED: To reduce the time required for maintenance by cleaning and lubricating a door rail of an elevator stably for a long period, in a device for cleaning and lubricating the door rail of the elevator.SOLUTION: A device for cleaning and lubricating a door rail of an elevator slides a cleaning/lubricating member 1 on the door rail 5 in a manner of being operatively connected with opening and closing of the door. The device includes: a flat spring 22 arranged with its longitudinal direction parallel to the slide direction and extending in the slide direction so that an elastic force of the spring can act in the direction perpendicular to the slide direction; a fixed part 21 arranged continuously from an end part of the flat spring in the slide direction and fixed to a moving body 4 operatively connected with opening and closing of the door; and a cleaning/lubricating member holding part 24 arranged continuously from a free end of the other end part of the flat spring to hold the cleaning/lubricating member in a space between the flat spring and the door rail.
