<P>PROBLEM TO BE SOLVED: To provide a device for oiling of a guide rail for an elevator, allowing reduction of soil by oil, reduction of oil consumption, and reduction of a maintenance working time taken for cleaning and an oil feed by preventing a surplus oil feed to a guide rail guiding upward/downward movement of a car of the elevator or a counterweight. <P>SOLUTION: The device includes: detection rollers 2 abutting on the surface of the guide rail 1 guiding the upward/downward movement of the car of the elevator or the counterweight and rolling; and a movable oil feed part 8 allowing a changeover between contact and non-contact to the guide rail 1. The guide rail oil feeder detects whether an oil feed to the guide rail 1 is necessary by the rolling of the detection rollers 2 in time of upward/downward movement operation of the elevator, and performs the oil feed based on detection results thereof. <P>COPYRIGHT: (C)2012,JPO&INPIT |
