<P>PROBLEM TO BE SOLVED: To provide an elevator guide rail oil feeder which can simplify a configuration while reducing the change of a quantity of oil supplied to the guide rail generated by a change of a temperature. <P>SOLUTION: The oil feeder 3 which is prepared in a car 2 of the elevator to supply oil to a guide rail 1 guiding the car 2 includes an oil storage reservoir 31 which stores oil, a fixed wick 32 which is dipped in the oil stored in the oil storage reservoir 31 to touch with the guide rail 1, a movable wick 33 which is dipped in the oil stored in the oil storage reservoir 31 to displace between a touch position touching with the guide rail 1 and an alienation position separating from the guide rail 1, and a displacement device 35 which displaces the movable wick 33 depending on the change of the temperature. The displacement device 35 has a deformation member 353 composed of bimetal which deforms according to the change of the temperature to displaces the movable wick 33 accompanied by the deformation of the deformation member 353. <P>COPYRIGHT: (C)2013,JPO&INPIT |
